The t-con board usually fails on this model (Vizio E601i-A3 and e701i-A3) resulting in sound but no picture. Watch how I repair the t-con board with a $.54 cent transistor. The problem is noticeable when it seems like the tv is not turning on. You may hear sound but nothing is showing up on the screen.
Specs on the transistor replaced: MOSFET 60V 2.3A 1.66W 156mohm @ 10V

This reminds of an old joke about a repairman who was called in to fix a household appliance.
He said "It's a bad screw, it'll be $100 to replace"
The owner was in shock, $100 for a screw???
Repairman explained "well, it's $1 for the screw and $99 for knowing which screw to replace!!!"
It's $0.54 for the component, $15 for shipping, $150 for hot air rework station, $75 for solder station...

@@artgoat 50 bucks for new tcon board
@@artgoat that's the investment once you know you how to fix things you get things for the low and can resale them and make your money back ain't nothing too complicated 🤷🏻♂️
Exactly !!!!!!!!!!!!
Last week i bought and repaired a 42" Smart TV for $5. Is the first time in my entire life i'm having a decent tv
That is so amazing to hear! Thank you for sharing. Keep it up!
I repaired TVs for 22 years, starting with sets that still had tubes, later transister and finally IC chips. The new technology works great and has excellent features, but is too small for this old guy. It's a young man's technology these days. Bravo to you working with such tiny components.
Thanks! Working with a microscope makes it very doable. In order to record this video I couldn’t use my microscope and instead had to watch through the tiny screen camera which is partly why I had trouble holding the transistor steady. I just upgraded to a trinocular one so hopefully videos like these will be easier to record.
The good old days. Technicians back then used to do things like design and build their own Pay TV Decoders. My version, cost about $5. It did not require a power supply of its own, since It pulled only 15 mA, and thus you could just install it inside a TV converter and then tap the power from the TV converters 12 VDC line instead. The decoder PCB was 4.50" x 1.20". To install, you just had to cut the baseband video wire, the wire that leads from the demodulator to the modulator, and hook these wires up to the decoder PCB's input and output. Anyhow, it decoded the baseband video signal line by line, rather than use the complex frame by frame PLL method. Later on I tried to sell the design to a cable company. But they said that my design was too good. Meaning that it was far to easy for it to be copied, due to it having so few components, components that were also readily available to just about anyone.
Yeah i remember i was kid and a family friend come to us to fix our black and white tv....watching for hours searching the fault and the smell of the dust and hot tin i will have in my memory for ever.
Well I was wondering if you could help me with a problem I have a 55 in LG TV that I bought off someone and it had a picture perfect picture on the internet part you know show settings and all that but when I brought it home to hook it to my internet it kept saying put in passcode I put in Pasco says it again so I tried to hook a DVD player up to it and the screen turn white and fuzzy it has sound but you know it's white and fuzzy picture but when I unplugged the DVD player it just has sound and I don't know what it could be it doesn't have pictures you know of people or anything on it like it should have but it's perfect when you go to settings it's like nothing's wrong with it on settings
Paul, I come from the same background. When I started, my very 1st TV that I repaired (yes I still remember it) was a 1955 RCA Color roundie) LOL
'Same as you, tube sets, hybrids, transistor, chips and modular.
Parts are in fact so much smaller now. I actually stayed away from SMD stuff because of concerns of being able to work with such small components.
But then, I just said to myself... SELF, get off your duff and just do it! LOL
So I bought all the toys... I MEAN... TOOLS (cough)... electronic microscope, superman mag headset, SMD station and just recently, a vacuum solder sucker gun and an SMD oven... well... just a toaster oven that I modified using Arduino to use as an SMD baker. LOL
Now, I can say that I just love SMD work, even more than old-school, through board.
That being said, there are some boards that I have that have the SMALLEST PARTS I have ever seen. LOL Literally, you have to hold your breath around them (if not soldered on) because they will blow away.
But yeah, love it now. The electronic microscope was the best thing that I ever bought. Mind you, I don't use its own little display. Rather, I bought a nice 24" screen with HDMI input and it's just amazing.
“Need very steady hands for this”
*proceeds to demonstrate severe Parkinson’s*
Lmao
😂😂😂🤣🤣
😭😭
Hahaha got the giggles 😂🤣
He needed to use his right hand to hold the transistor, and his left to hold the heat gun, he would be more stable using the hand he is more used to using for small parts.
I recently fixed my 60" tv by replacing it with an 92" one
😄😄
@Eìon O'hInneirghe Get more triggerd plz
Eìon O'hInneirghe if u really think about it... nobodies idea is ever original
Hey man, you doing ok?

Super valuable video for a common fix on the TCON board for these Vizio models. I can't thank you enough; Vizio is all my family uses. Thanks for the tool descriptions in the notes above as well, also valuable info. These are the fixes that never make it to any manual, and it's so cool you took the time to explain it.
If you don't have the tools you can also use a cheap soldering iron of around $25.
To remove the broken component, heat each solder joint separately and use a sharp knife to bend up the pin while the solder is heated, so it's not touching the solder anymore.
To solder on the new component, put the new component in-between some tweezers and lower the side with the single pin just a little, so this side touches the solder joint first.
Heat the solder while lowering the component in place. When the side with the single pin is soldered, the pins on the other side should slightly touch their solder-pads underneath,
then complete soldering by alternating between both left over solder joints. If you notice you are bending the pin on the other side a little to much, just reheat this side quickly to release the stress on this pin.
or you can use a lot of solder, just make a big glob that will get cold slow and take the part out with tweezers. Clean the pads with a wick, place component, solder 1 leg while holding the part and then solder the other 2. Much easier and cleaner.
The amazing thing is how little is actually wrong with these tv's. This is a wonderful channel to clarify exactly how you fixed these models. I can't wait to take another look into my bad tv because it could well be some very inexpensive part(s). Very helpful! I enjoy fixing stuff too.
Good job, thank you for teaching others this kind of skills.
I did the same thing with my 3k, 10 yr flat screen by replacing four capacitors for $1 plus $4 in S&H 2 yrs ago. It was the first time my adult son got the chance to watch what his mother use to do for a living when he was a toddler. It impressed the hell out of him, lol !
thats pretty cool.
Nice job on the video. Very clear photography. I really thought this would be a video about a bad capacitor. I have a ~15 year old LG 27" 1920x1200 monitor that I fixed many years ago. I learned what was wrong by searching the Internet forums. My search taught me about "capacitor plague." Ballooned cheap knockoff capacitors that caused many electronics to prematurely fail. I replaced the bad capacitor and my LG is still going strong today. I agree with you. The Internet is a wonderful resource for DIY'ers.
Thank you! Great to hear you fixed your monitor. Yes, so many tvs and monitors were hit by that "plague".
Awesome please keep making videos they are much appreciated
You're the man! I have a 60" TV in my basement right now waiting for me to replace some capacitors!
Keep us posted how it goes!
Great clip! I was a TV repairman (old analog TV). Your video is really good, especially for techs, but I doubt an average person could do such repair (mostly due to the lack of tools and patience).
Thanks!
@@FrugalRepair How it U know what to fix ?
I fix many touch screen 47" LG Using bypass method in different spareparts and it works but surely doesn't sure 100 % guarantee, beacause sometimes the value of the component is erase or none...Congrats to you bro!
Are you sick Mr Rossman? You sound funny today and you're fixing TV's instead of MacBooks
joblessalex Louis doesn’t solder that bad
Great how-to video. You explained it well enough so that I feel confident enough that I could do the repair on my own TV if need be. The link to Ali-express for the soldering iron and hot air combo was a nice touch because although it is cheap equipment, it would probably last long enough to make a few repairs and save me the cost of replacing the entire TV.
Thanks! I’ve been buying a lot more from AliExpress this past year and I’ve been happy so far.
Congratulations on the repair. It's a very rewarding feeling. Greetings from Arizona.
Thanks! Yes, this repair was a lot of fun.
OMG you a tech genius, u saved a tv that had the exact problem but different model my tv was model 43R6E3 and it worked! Thank you for the pointer as soon as I saw the video I knew we had the same problem.
Congrats on the repair!
First time I see this man.... I paused the video at 0:19
Because that's enough for me to subscriber
Coming back later to watch more...... I love people like this on TH-cam.

Turn on then turn off
The most important part you forget to mention, how did you find the wrong component? need to be tested all the components?
If you search online there are forum posts and even other videos that explain this transistor is a place to start your diagnosis. I didn't spend very long on the diagnosis since others had helped point it out. The internet is a great place to help solve problems.
Agree, this is just bs component troubleshooting, no instrument. Continuity is useless on on board/soldered component.
@@Sal112350 you are incorrect, sir... continuity is a great way to test... but, he failed to actually prove that the part was the issue. He should have tested the continuity on the board again AFTER the apart was taken out to show that the part was causing the short and not some other component on the board. THAT is the proper way to do a continuity check.
@Derp The answer to your question, Derp, is bad design. The transistor in the circuit is running "hot" (over 70% capacity) regularly and if the transistor quality is weak it will go again over time. But this knowledge has little barring on the propose of Frugal's presentation. He tested the part, it needed replacement, and he showed how to do it. If a person watching tests the part and it isn't shorted... they should find a different video to fix their problem :-) .
@Derp You sir, are correct. After doing this kind of work for around 40 years, knowing to check components on the secondary side (for the lack of a better term) of this transistor is a must. If another part is shorted, leaking, etc., it's pulling too much current through the transistor so it failed. Sometimes you get lucky. Lot's of times you don't. If that transistor popped, what does ''the internet'' say then?
Well done! This is a great help for DIYers like me.
Thanks!
Love it. Right to repair! Well done, Frugal!
Thank you!
Thanks for giving this knowledge.
this is your bread and butter, how reg joe gonna know that transistor is the culprit?
How didnt you see the moment where he is measuring that very component.... It isnt that far fetched that understanding its inner workings it is much easier to go and look for failed components. Because they are most commen to fail just hard to find if you dunno what is controling what. Just grab yourself some broken tv a multimeter and go have some great fun. But remember to stay away from the high voltage area...,if you dont you find out really fast why. Good luck! Stay safe!
Most issues like this can be quickly checked with under $150 in tools, and a quick google search of " common problems". I have done this numerous times for all sorts of various electronics and it has saved me not only thousands of dollars in repairs, but hundreds of hours of manual troubleshooting.
I fixed my visio for free. Found a bad fuse, a non-serviceable ceramic one. Took a single strand of copper wire and soldered to both pads right over the bad fuse and viola!!
Please don't do that
A viola is a musical instrument (much like a violin) and chances are something else will fry up now with that copper wire. Remember that fuses blow for a reason - if you don't find the reason it will happen again and just cause more damage elsewhere in the unit.
It's been working fine for years
Thats amazing, my brother did this to his TV and got it to work just fine, thank you for the video and pointing people in the right Direction!
That’s great to hear!
I know this is old but you just gained a new sub, i have 2 65" tvs that were replaced by LG a 2016 model and the other a Vizio 2018 model by Best Buy...i followed this Video and fixed both now i have 2 new 65" Vizios and a decent LG..THANKS
Great job fixing those tvs! By chance, did you have a problem with the power supply on the 2016 LG 65"?
@@FrugalRepair no i actually swapped out the tcon board and the Visio had a bad conduit on its tcon board
I fixed our Samsung a couple of years ago - replaced a couple of transistors on it. Great tutorial! Looks like you’re channel is doing great! Thanks for subscribing to mine. 👍
Awesome to see you've got a YT channel with some great content! Way to go fixing your tv too. Did you perhaps mean replacing capacitors?
FrugalRepair Right, capacitors. Thanks for that correction! Good to hear from you.
I don't bother fixing it just wait for exchange replacement program and get rip of it...
Congrats fixing your big screen TV it's nice, a big thumbs up 👍and shared.
Wow, I'm honored! You made my day. Love your channel. Thank you!
Screen is tore half an inch not cracked can we fix it
You mean that there is a scratch in the screen? You probably can't fix it but you can minimize the damage a little bit. The part you touch on the lcd panel is the front polarizing film. That is glued on to the lcd with clear adhesive. Its been a while but depending on what kind of scratch and how deep, I've used a pencil eraser or a black permanent marker to mask some of the imperfections.
But now he end up with Vizio...... Not sure that a good thing...
please send me the T-con number for JVC MODEL LT- 55N875 smart tv
As an EE, I salute you for the knowledge of an appliance, plus the incredibly small working parameters. I've never thought of using a heat gun in lieu of an iron, however small.
Thanks! I studied computer engineering, all those EE classes have definitely helped me understand what components are and what they do.
@@FrugalRepair so when the screen is black it's most likely the T.comm board and not the main board,I'm asking for a friend. .....
Thanks for this.. had the same problem.. now fixed.👍👍👍
So great to hear!
Hi Fugal, thanks for the video. I suggest you adjust the air flow on your hot air gun as surrounding SMT components may be blown away, and you can notice that in the video when the diode above the transistor started sizzling, and if they don;t get blown away their soldering will dry out hence making it a dry joint. The trick is to use a good heat with less low air flow, that way the heat contact is precise on the bad component.
I agree. This is not my best work. I was excited plus I couldn’t really see what I was doing since my camera was so close and covering the board. I have a microscope camera now so that won’t happen again (hopefully).
Good job. Give us some diagnostics, so we can "learn" error tracing of broken components. Keep up your great work! :)
Thanks! I'll bear that in mind for future videos.
That was a very good and professional repair
I got my Tv from This guy and it still works perfect. Thanks man.
That’s great to hear!
Have the exact tv and the same problem. Your fix worked great! Thanks!!
Cool! Thanks for letting us know.
@Enoch Pedersen I put the specs in the description so anyone can hunt down online for a good price/option. I'd would first check on aliexpress if you can wait for it to arrive from China. Otherwise, check with any of the US suppliers.
@@FrugalRepair i have the same tv model but the 70 inch .....e701i-a3 with the same exact problem. so this will work with the exact part u replaced with?
@@MrHontas83 The tcon board would be the same. You would need to either test the tcon board for other failures in addition to this transistor to make sure or you can replace the transistor and see if it worked. It is very possible that there are more bad components on the tcon and it is possible that your lcd is bad and thus not repairable. You can also simply buy another tcon board on ebay for like $17 and pop it in quick to see if it fixes the tv.
@@FrugalRepair where do I get the machine to test and what's it called
Hmm...you too can fix a flat screen TV for $0.54...if it happens to need this particular transistor, never mind how we diagnosed the failure, and you have a hot air rework station. I once saved a stereo receiver with a $1 capacitor, too, but that was the only lucky shot I’ve had. The other jobs took a lot of troubleshooting and had more involved failures.
he coulda fixed it with just a soldering iron. but I understand what you mean. my mate fixed a four-year-old 60inch telly using NO parts. (just squeezed up a screen connector). but I think it's worth having a look if you have a few tools and basic skills - if you can't fix it, there's nothing lost. if you can it's a result
Thanks for sharing, in this day and time we need to change our way of thinking. With the pandemic that has arrived there's going to be a point where there will be issues of being able to afford the luxury items that we have been accustomed to buying. We are definitely going to need to repair what we once threw away, or the option will be to do without. If one thinks that the Great Depression was only a thing of the past, you're in for a surprise. You've earned a new subscriber.
Thanks! Great perspective.
Thank you for this great info! I replaced the culprit mosfet with a random mosfet I desoldered from a random board. The tv turned on for a few minutes before blacking out again. This confirmed your suggestion that the mosfet is burnt. I can now go look for the correct spec mosfet to repair my tv. Tv is a SONY KDL-70R550. It’s an old dog but if it costs 50cents and a bit of sweat to repair I’m happy to continue using it.
That model uses the same tcon? Keep me posted.
FrugalRepair it’s using the 5348 board but the layout is identical. I’ll keep you updated with further developments
I couldn’t find the mosfet of the exact spec that you specified so I tried my luck with a SI5328DS mosfet rated for 100v. It works and the tv is back working
Fix the car
Most solder has flux in it and also I would never use hot air station its risky and for repairing one thing its pointless.
Just use a soldering Iron it's cheap and it works well and its safe if you use it right.
My thoughts exactly.. For a 3 pin component it's useless. Just pump the solder from the board, put the transistor on place, and solder it with a simple iron..
@@freeeflyer Did you mean: suck the solder from the board...? I have a solder sucker...never heard about solder pumps... :)
@@bror8228 If you need to desolder lots of connections, you can buy a solder station fitted with a vacuum pump and nozzle.
Who needs a solder suction pump for a job like this? Just use solder wick. Should have cleaned off all that excess solder so the new part leads are in contact with PCB with minimum solder in between. That huge pile of solder this guy used is more likely to crack than if it were minimal.
Also soldering one leg to tack it in place with an iron is easy and then you only have to touch the other pads after you have cleaned and added new solder to the pads.
Newer TVs are easy to fix now even if you do not want to change a transistor you can buy the boards cheaper than buying a new TV and just replace the board. I have fixed a few TVs over the years. The old tube TVs were easy you just pulled the tube out, took it to Radio Shack and got a new tube and replaced it lol.
Exactly. Swapping out boards is pretty easy and you only really need a screwdriver.
No doubt the TV repair chains lobbied for tv's with no tubes so you'd have to pay a technician an outrageous fee to replace a 5 dollar circuit board. I remember fixing my own TV many years ago by testing for those burned out tubes. Cars were owner repairable also.
@@kenjsr1 Valve TV's?? you still in the 60's? LoL. Music was good, TV's were rubbish.
I enjoyed watching this video, especially the soldering works for the new transistor. It s like watching man landing on the moon.
Than you for the encouragement! I think I did a better job explaining the soldering process on the 65” 4K TV video. Did you get a chance to check that one out?
I myself loves to tinker alot with electronic stuffs. I hope to learn the troubleshooting skills you have, not just the visual check. So, with this, you got a new subscriber! 😁😁
Such a coincidence, a friend of mine was about to do that same, same exact model. Took it apart and pulled out the board. Did a multimeter test and the results were the same. Now I just need to put in an order for a new one. I really hope this works because my Xbox is lonely. Ill let y’all know what happens when I get my transistor. 07 salute!
Glad to hear you are fixing it!
replaced the transistor and it works! thank you for making this video, 07 salute!
Wow, that is great to hear! Way to go replacing it.

Thank you for the encouraging comment!
I just picked up a vizio 47" tv for free the seller described it as the backlight went out on the right side, so I brought it home (this is my 5th tv I've fixed from my crona quarantine away from school for the past months thanks to you! Btw lol)well I decided to plug it in to see if they where correct and all the sudden I hear it squeal and smoke comes out of it!!😂 well I take it apart and look at the backlight inverter on both sides sure enough the right side was burnt from the capasitors smoke and the left side capasitors where bulging so I ordered 5 new ones I only need 4 but why not have extra lol for $6.99 and now it's running perfectly strong and has been for a week. Sorry for the long read but I figured I'd put my story if it might inspire someone to get after there broken tv and fix them.
That’s so great to hear!
If you prepare the lands as you did, plenty of flux and use a soldering iron to make each land. DON'T use hot air to place the new component in!
Right. This was almost like a "how not to" video for SMT soldering. I was cringing the whole time.
Any problem with hot Air? I mean some do solder set with hot air right any reason to avoid it?
Jon C. - unnecessary for this particular component with three leads. If it was a chip with lots of leads, then a soldering iron won’t be the tool to use.
Sweeeeet!
Now maybe I can Fix the 60” Flat Screen I pulled out of the Transfer Station/Dump!!!
Is it the same model as this one? As long as the lcd isn't cracked you have a very good chance of fixing it.
Thanks man I appreciate your efforts.
Just found your channel, the issue with my vizio is all the input ports stopped working so we cant plug anything into it. Lots of great stuff on your channel, I also try to help people save money by fixing thigs. Thanks for sharing.
the upscriber
I fixed a 60" flat panel that I paid $50 for at Goodwill. I'm not as skilled as you so to diagnose which board needed replaced I just looked at all the boards for a burnt mark left where it let the smoke out. A new board cost $27 and only required a screwdriver to install.
That is awesome to hear! Great job!
Oh,, your tv is dreaming inside a dream..😱😱
Hi, i just want to thank your video, mate. I repaired a Sony 60'' with the same symptom. But in addition in my situation, i had to cut the left cof tabs. The MOSFET used in my case was the Si2308BDS.
...to me, it is very good news to watch during the lockdown of COVID-19 ...
Touch a 300v capacitor and it'll enlighten you to the dangers of home TV repair.
That being said its a miracle my heart hasn't exploded over the years.
I mean... we got taught that if we ever wanted to open anything with big capacitors we should wear protective gloves and prioritize discharging of the capacitor.
Yeah, but not as bad as touching the high voltage contact on a CRT ... I’ve seen that knock someone flat on their back side...
Yes, I fixed several LCDs just by replacing a visibly leaking capacitor!
It's repair 101... (1) look the board over with a magnifier, are there any burn marks (change the burnt stuff) are there any dry joins (reflow them) are there any board cracks or scratched traces (bridge the gaps with wire), are any caps leaking shit (change them) (2) Check voltages Mains, DC voltages at chips etc (3) test shorts/continuity on fuses (should be), transistors (shouldn't be), caps (shouldn't be) etc etc... most of it is common sense...
What were the symptoms your tv was showing was it not powering up by any chance.
There I no such as a visually leaking cap...wives tale extension there is no leak you can actually see in a leaking cap It just means the cap is leaking voltage not leaking a substance so...you have never fixed anything by finding a leaking component since there is nothing to leak out of it. b.s. called you shant recover back peddling not allowed it's just a bad lie but why did u lie there's a deeper reason me think
Lie no such thing as a visually LEAKING CAP there isn't anything TO LEAK OUT only voltage drops that what leaking means ya moron not like a substance leak so I gues you have x Ray vision I f you can see leaking voltage lol ....I hate b.s. liars
kirk watstien - you ain’t seen nothin’ yet if you haven’t seen a visibly leaky aluminum electrolytic capacitor. They have a discharge vent on the PCB end, and the leaked electrolyte is often visible on the board. And they will also pop their lid, which is quite visible. No BS to this, you just haven’t had enough experience with all sorts of varied devices to have seen those.
Absolutely awesome. Love your channel!
Thank you! What a great comment to wake up to in the morning.
I did tv and radio servicing C&G 224 many many moons ago, it was all analogue back then everything was solid state..... very easy to fix compared to these smd's you deal with, respect to you.
Thanks! The biggest hurdle I find is lack of schematics and board views. It takes a lot longer if you have to reverse engineer stuff to figure out the problem.
It’s the skill of finding that failed part that makes the repair bill, plus your soldering station, access to schematics, multimeter, etc.
schematics.... many of electronicians don't use schematics for fixing boards, we uses them 20-30 years ago, now theire not avaiable for the most of them. So, we tests, we try, and maybe we fix...
And more modern boards with macro smd's no chance repair for diy .....
@@leso204 1206 SMD models (and biggers) are not so hard to tests and replaces, but for the tiniests ones (402, 201 and smaller), i'm ok with you, what a pain to try to test and even more to replace :/
A popular question I have been asked is: "Are you making more videos?" Yes! I took a break from making repair videos to design and install a 15.6 kw solar system on my house, (more on that to come) but for now, here is the latest video: th-cam.com/video/fesJGOLurBg/w-d-xo.html
Thanks for the video and repair tips. First time i have seen the inside of a flat panel. Good job.

I like fixing stuff (cars, Electronics, i.e. whatever breaks around the house) and nothing compares to the feeling of knowing you just saved your self big bucks or, even better, now can sell something that was worthless yesterday. I've got a couple of flat screens that you've encouraged me to tackle now. Cheers

Less than $1 if you have tools ready
And schematicvs of the module, probably not less than $20.
No chance he weould get the right transistor type from that marking alone...
@@BB-ce3bj making he looked in an online forum where someone had the same problem
Wilcon Barro Yes. As with most repair jobs of any type, you will need tools. They probably cost a lot less than the repair shop or the price of a new TV though.
Multi meter is like 20 bucks at Walmart.
Soldering iron 10-15
Flux 3-4 bucks or free with soldering iron
"Fume extraction" get a house fan
Hot air shit not necessary and most likely you'll damage something else if you don't know what your doing not worth the risk
Les then 40 and you'll have useful tools in the future just in case.
Way too much flux. But good job fixing it!
The bigger the glob, the better the job - Louis Rossman - 2017
You didn’t clean the flux residue off. At least wipe the area with a flux cleaner pen as a final step.
Enough FLUX to do a plumbing repair and far too much SOLD ER.
I really like your channel personally .... You provide very good content...

@@FrugalRepair I just watched it. It's amazing all of the tricks you have picked up repairing these TVs. I actually have a 50" Samsung Plasma TV that has one green vertical stripe. It started doing that at 1 year of age and I just quit using it. Since I never throw anything away, I still have it. I'll have to peruse your channel to see if I can look for pointers on repairing it. Of course, it was replaced with a 4K LED TV that blows it away, but it'd still be fun to repair it. I originally came to your channel to show a friend how to look for lightning damage to his TV. Thanks for putting out such useful content and taking the time to help so many. You're banking a lot of positive karma.
Thanks, that’s encouraging for me to hear! Lines on a plasma maybe a relatively easy fix. It is possible (but I don’t really know in your case) that the ribbon cable needs to be cleaned and/or re-seated. You need to have the tv unplugged then locate the ribbon that controls that section where the line is. I bet there are videos about it. Those ribbon cables are usually at the bottom after you take off the back cover. Usually they are connected to the Z-board. You can google that.
Very cool. How about when the tube has blown due to an apparent lightening strike ?
Thanks! I have a video about what to check after a lightning strike. Check it out and let me know if you have any more questions.
That's GREAT! I have to same problem, just one question, WHAT IS THE PART NO, SPECS, HOW DO I GET ONE?!
Good job. I just use an iron and solder wick to remove and flux and solder and iron to replace. Though your biggest challenge was holding it steady while recording and you did good considering.
No longer apprehensive about purchasing a Vizio again. Thanks.
You probably can't know ahead of time who makes the TV until you open it up. Vizio doesn't make the TV's actually. Usually the manufacturer is LG, AU Optronics, or even FoxConn (who makes iphones). I've even seen the same exact vizio model made by different manufacturers.
As an experienced electronic maintenance engineer I don’t use hot air in this big transistors but tiny tip soldering iron. Also you use too much flux. If you want to do this, just get desoldering wick like Soderwick which is the best brand, and tiny tip soldering iron. Then remove the transistor using the wick and soldering iron. Do not buy too narrow wick as wide wick coolens the soldering point and protects the board. Then put a little amount of flux (which is usually not needed in this large components) and solder the transistor with the iron. Don’t keep the tip more than a second. If it does not work, you have too cold tip. Do NOT use leadfree solder but old fashioned 60/40 tin.
mattikaki I wick the pads, put a small blob on the collector pad, place the part heating just that one then solder the B & E.
Too much flux? With that attitude you couldn't survive 2 minutes of a Louis Rossmann video. Just gotta throw your TV in the ultrasonic pool in the back after done.
As you're never going to re-use that old transistor anyway, I just cut off the pins with a tiny side cutter, then pick up the individual pins with the soldering iron. No risk of damage to the PCB pads and works equally well for all but the smallest chips.
My TV has no fanspin now. Thanks. :(
I was taught how to use solder wick in the Navy and found the same thing as you, it rarely works well on small electronics, but on some of the tube-era gear we worked on it sometimes worked, otherwise I agree is just never worked well for me, solder-sucker is my go-to method.
Well but if you don’t know where to look, its an awfull amount of transistors and capacitors to test.
Frickin awesome man! Will subscribe and thumbs. Can’t wait to see something that applies to me in the future.
Keep on truckin
Thanks! More videos like this one coming soon. Let me know if you have any suggestions.
I have a 60 inch LG plasma that needs a similar repair. But I’m so scared To break it even more and I’ve never seen the tools you’re using before in my life other than just a basic solder gun. The TV is 600 W to run but it’s bright as the sun and crisp as a rainbow. I repaired it once by replacing the motherboard but accidentally gouged a little piece of solder.. stopping it from Booting up all together. I’m very confident that your technique will allow me to repair this incredible plasma. Just need to know more about the tools to get me there
Oh man! I could beat this guy at a game of Operation!
Heck yeah!
HAHAHAHAHAHA!!!
I pickup tv,s like this all the time and fix for pennies.
Sweet, thanks for sharing the knowledge.
Thanks for your comment!
You make it look so easy because you don't show your methodology in fault finding. You certainly are a showman rather than a tutor.
Smartass guy... 0.54 cents for a transistor, 2 hundred bucks for the tools... knowledge, practical work and warranty are priceless...
Vanderlei Oliveira yeah but you could do it with $30 - soldering iron, solder, and desolating pump/wick
@@ericrann but that requires more than 54 cents worth of common sense ;-)
Can you help me fix my flux capacitor I’m stuck in 2018 need to get back to 2055 😁
Haha! One of the best comments on this video. =)
No wonder your flux capacitor failed. It says "made in Japan".
good electronics only come from Japan :)
Just add new flux.
Did back to the future fuck the time line? Do we ever get flying cars?
I learned something new today.
I don't know if you couldn't use the hot air gun due to camera constrictions but it works a lot better if you can circle all the joints and not just focus on one side. Great video!
Impressive, but how did you diagnose it was that actual transistor? There was a lot of stuff on that board.
Testing multiple things, then put back together, then make video.
Or.... research issue on model and see it is very common failure, then make video hoping it works ..
Probably read up on it on a repair forum online ...
Oh, he answered that same question in another comment - watched a different TH-cam video!
It was painful to watch you trying to work with those tweezers lol
I would be the same way. That is a small transistor. I get the shakes when soldering small stuff also. :(
yeah i cant bear to watch him using those tweezer
Same feeling
Oh the perfect people can't stand it. Must be nice to be so flawless. Douchebags.
@@MasterMolded, No one is claiming perfection. It's simply about avoiding damage to the board. Rocking a component like that before the solder reaches it's melting point, can rip the pad right off the board.
Definitely not a fun situation to deal with.
You are marvelous, awesome. A congratulations
Thanks!
Impressive. Especially the Visio mind meld when it told you which part was hurt.
Ha ha! That’s called TH-cam.
I repaired my 10 year old $2400 Samsung LCD for $3.50 by replacing 2 bad capacitors on the power supply
I find that the longer I live, the more capacitors I have to replace!
Yeah i had a pretty similar case once, where i just had to replace one cap.
Kinda funny how easy it is *some times*
Samsung TV's from 8-10 years ago were notorious for a bad batch of electrolytic capacitors. The company did a great job of repairing as many TV's as possible within a reasonable warranty period but you can only do so much. I repaired one 2 years ago that was out of warranty, for a friend. Capacitor kit was $12, shipping was $8. I volunteered my time(less than 2 hours) For $20 she had a functional 46" TV. Still works great today.
I did the exact same thing! Always check to see if what ever you have has a fixable problem.
Great job fixing it!
Question is how did you know out of all those components that one transistor was bad? Did you test all the components on the display board or something?
He literally explained that this was just a suspicion before testing. Many repairmen work like this. You don't have the time to check everything so you just move down a list of parts that have a high likelihood of failing. If this TV is known for a particular part failing then why even bother with the other parts?
He watched another TH-cam video on this common issue..
You help really help me to fix horizontal lines
I like your mood sir when u are repairing, your follower from the Philippines
Thanks!
May I please ask you a few noob questions, I am not criticizing you but honestly try to learn from you:-)
3:22 why do you choose hot air instead of bent thick copper wire wound around your soldering tip?
why do you not use something like capton tape to shield the other components from the hot air?
Hope you please will teach me, so I better understand.
I hadn't thought about bending coper wire on a thicker soldering iron tip. That is a neat suggestion if you don't already have one with a fine tip. It still might be hard to solder in a small component in a tight spot with that setup. I'll have to try it sometime. I didn't feel the need to add kapton tape since the nozzle is small enough and the hot air can be directed to the one component. It depends on what work you are doing though. When working on an iphone board, for example, I may use kapton tape and place a metal coin nearby to help absorb some of the extra heat.
@@FrugalRepair Thank you for your great answer. About the copper wire, I find a thickness that I seems to fit the task and then start to bend it until it sits nice around the chip and let the tweezers and heat do the rest:-)
Also wary nice and hard to reach places, like under a capacitor, in the corner near some plastic. You can always put an insulating tube around the 4 inch long copper, if necessary. :-)
Your explanation about the heat gun, do make a lot of sense, I do just not have enough confidence and knowledge yet to dare that. It takes a bit of knowledge as you clearly have!:-)
How did you determine which transistor to get?
model number on the trans maybe ?
It was probably a common issue with this set.
@RS2002 He checked online for people with the same issues as his TV.
He said in another comment that he watched it on a different TH-cam video!
Last December, one of the sales guys where I work was tossing a Hisense 50H7709 4K 50" LCD HDTV. It was still under warranty and after a tech tried troubleshooting it, he authorized it being replaced, so he got a brand-new replacement. I asked him if I could take it instead of tossing it and he said yes. It would power up, show the Hisense logo, then shut off again. I looked at the power supply board...BLOWN CAPS! Easy fix! How the tech didn't see it I'll never know. Anyway, ordered 4 caps (2 for the fix, 2 just in case), replaced the blown caps, powered up and worked beautifully! I gave it to my daughter as a Christmas gift. The shipping on the caps cost more than the caps themselves. Just over $8 Canadian in total.
(I may have posted this before, but I can't remember. Please forgive me but I love to brag about this one.)
Good instructions thanks. This might be the repair needed for one of my two Vizio's crashing in the same two weeks. I'll explain both situations and hopefully you can share your thoughts on diagnosis. TV. #1, Backlight certainly works but losing color, contrast and brightness as the picture is starting to blacken out in top left corner and bottom right...almost is rectangle shapes in each corner. Picture is good after a rested restart and the problem quickly creeps back in. TV. #2, our oldest Vizio maybe 8 years, 50". First sign of a problem was the quick App start brand bottoms at the bottom of the modern FireStick would change the TV input to an unused port. Next problem it would blackout and flicker back on with clear white horizontal lines. Then it flickered until it don't come back. After long rests it worked again a couple times, V logo came up, with sound, and was back out within 10 minutes. Now it's out-out with no sound of the FireStick clicks changing the Apps, no V logo and all black screen...no backlight. With was a 2 month fading experience from beginning to end.
forgot to tell that you put _i dunno how many years of study_ your knowledge under 1$ price.
but well done.
Thanks. I think you give me too much credit though. I don't think soldering in one component takes years of study and knowledge.
@@FrugalRepair :) ty. Maybe not many years but you have a background to do this. I understood the real meaning if this vídeo. I didnt meant to be rude...
@@fshimage No problem, thanks for your comments.
@@FrugalRepair at all. Actually I think using a heat gun was the hardest part. For one component with three leads you could of even used just solder and a soldering iron and popped one lead or leg at a time. But doesn't matter the job got done and the set now works.
ive been fixing TV'S for a long time, and its the first t-con board failure such as this ive ever seen. the title and info in this video is very misleading. lets not forget the shipping for the part at least $7.00. also, this part is UNIQUE to this sets T-CON board. don't run out and buy the transistor listed thinking it will fix your set. you can have the exact same model TV and have a completely different T-CON board inside. He shows us nothing of what it takes to trace down SMD transistors that have next to no identifiers on them.
Was wondering how the "This is a common fault with this set" is known. In my day, OK it was with valves :-) the schematic diagram was rather simple. Other than using a LOT of flux, an example of changing surface mount components is shown. I do like the video, and must admit it's the first one from this chanel I've watched. Time to check out a few others....
Yeah too much flux and he cant move his hands for shit..
By the title alone I knew it was gonna be a transistor or a capacitor, you can fix a tv just by replacing one of those but you have to be lucky.
Mea Tter It’s usual to use a lot of flux when using a hot air gun. Finding the problem is up to you as an experienced technician, the transistor was just an example. Also if you work with these types of T.V.’s (vizio) as you would have seen that he has in his previous videos, then the transistors are kept in house. I keep quite a large stock of components for repairing P.C.’s.
This is just a “give it a go at fixing it yourself” before trashing T.V..
Too much? Just enough or even too little flux, and it would have been easier if he didn't pre-tin his pads.
Good job I have a few led tv that need fixing will have a go
