Someone got rid of a broken 4K 55" TV (TCL 55S405) that was under warranty. Their repair guy couldn't figure it out why there was a blank screen. They gave it to me and I tracked down the problem and fixed it with a small piece of tape. Now the image looks great! Stay tuned for part 2 where I explain more of why/how this type of solution works.

What was the best thing someone gave you because they didn't want it any more ? It could be broken or working. If broken, what did you do to fix it?
I got a $1400 laptop for $250 because it took 4 minutes to load windows. You'd click on start and it took 5 seconds to bring up the menu. They replaced the hdd in it and still same issue. It ended up being sold as "parts". Turns out the optane was dying. Replaced that with an m.2 nvme and boom! 10 second window load times. Great gamer and only $350 spent total. (technically not free, but $1050 in my pocket is pretty good)
Got an old smashed up iPhone that would have been thrown out. Did a lot of repair work on it, replaced the screen, and voilá - an awesome phone that I can use whenever there's a risk I could break the screen (a cheap replacement screen is 8$, a replacement for my normal phone is 80$)
Can a torn ribbon be fix with tape?or did need new ribbon?
A MacBook Pro. I ended up doing a workaround to avoid the faulty video card. Works great now!
Some one did give this flat screen TV the screen was broken and I place the screen another screen,not the screen for it,but when I check it was a bit shorter but the connection was good
I am a 67 year old woman who has always loved (since my childhood) to repair appliances. I had a 55" TV that was not working after only 3 years. I discovered this video and started to repair it. My TV is working great after a few hours to find the tiny little part to put the tape in. Thanks for sharing your genius!
Wow, that’s great to hear that you got it working again! Congratulations!
I too like repairing my own.... trying, I have sound now but still no picture :(
You and I have kindred spirit! I'm 62- my sister was getting rid of a 50inch TV because the picture unstable- the cost to fix was not favorable so I Google TH-cam did repairs and would you believe I came across a repair video same as this now I have a fully functioning TV like brand new! Fixed it in under 15mins! I have a Samsung 55 inch just like this one in the video to fix- the tech i took it to said that it can't be fixed but he wanted to buy if from me for parts but I declined- thank God I didn't - so I'm going in and try again to fix it for myself again...
@@debdavenat I replaced the t-con board (simple job) in my D32x-D1 Vizio and it fixed the problem. Also, I had a fuse go out on the power board on my niece's 43" Vizio. I replaced the fuse and she now has a great picture again.
I have a smart tv that lost sound it connects to the internet fine but it doesn’t get any service… what would would recommend ?
at last someone who actually explains whats going on. from one old tv engineer to another .respect
Thanks! Did you watch part 2? I explain it a little more (if interested)
What happens when some of those pins are black?
This guy really has a passion for what he does. He doesn't just look at the major parts for issues, he dissects the parts until he finds the issue that is creating the problem. That is a rare find in, any field of prepare work. Great job guy...,!!👍🙂
Thanks for the encouragement!
@JENASIDE
It's called troubleshooting. Like he said, it's a step by step process. It's how a real, trained technician of any discipline is supposed to diagnose the problem. There's no guessing and just changing out parts.
If they're doing that they're NOT a technician.
@@FrugalRepair I'm still unsure how to know which cable strip to apply tape to
I definitely agree. He should be teaching our students at any good school!!👍
Yes indeed he shows us the cause and how to go about
Well,,,,that was amazing how you went through those lines and found the problem, you make it seem so simple and easy. Thanks EJ
I been fixing TVs for a while and this was one of, if not the easiest fixes ever. Thanks a million. You definitely learned a subscriber.
Thanks!
My Samsung TV had half of the picture white, just reconnected t-con ribbon cables And works like new. This was easiest fix 😁
It's not exactly a fix, more a workaround. Not a bad one if the result isn't very noticeable.
This method revived my 3-year-old Skyworth TV. Two technicians said that it was beyond repair. Saw your video and proceeded to place the tape on the ribbon. After about 30+ tries, the 2mm tape saved my TV. Thank you from Malaysia!
Congratulations on fixing it!
Just found you today. They gave me yesterday a 75" qled Samsung smart TV. Haven't repaired yet. Cause I'm also a handyman/concrete/carpenter. On my way to and from my jobs I pick up fridges, water coolers, dryers and etc. Either I fix or remove parts. Already have a year doing this. After watching you the tv has no chance. I'll lyk when I get it running. Or for some advice. I'm bartering electrical work on his home for the TV. But he didn't commit me to it. The tv is new. Lamp hit it. Also he introduced me to my favorite fishing spot. That I happen to be the master of now. Since 1995. Thanks for your video.
Great video!! I love that you not only fixed it, but you explained every part of it along the way. It’s nice to know what you’re doing, not that you just put tape on it to fix it. 👏
Thanks for the kind words!
I must say man, after 5 years of DIY TV fixing this might be the single most useful tip in diagnosing picture problems. I have never ever heard of anyone talking about clock lines in any video, literature or otherwise and 've done a lot of research and reading on TV repair. You got my vote, subscription and like. Keep up the great work!
Thanks for your comment! Glad I could help.
Same here!
My mind is blown. It was really educational.
Great tricks my man!!
Agreed repair information now is turn it of and back on, reset the device on call manufacturer for an rma if you're still under warranty
Thanks Rees, I fixed our TV today, with a tiny piece of sellotape. I didn't have a clue where the clock wires were, but I tried each wire one by one, and within 10 minutes I had isolated the shorting issue. The TV looks greatnow, thanks so much! I'm so happy and I learned so much about monitors from your videos and taking the monitor apart, priceless!
You did such a good job explaining exactly how you were doing everything then I'm 100% confident I could fix this problem myself
That was amazing. I have been fixing LCD TV's since 2010 and never have I ever been led to this repair method. Of course I am doing warranty repair so if the T-comm board is replaced and I still have the same symptoms whatever company just replaces the TV. However I just got for free a nice 70 inch Vizio that has back light and when the menu buttons are pushed there is a faint raise in luminosity on the screen where the menu would normally be but no text or pictures otherwise. The luminosity gain follows when I scroll through the menu blindly so I know the TV works - just going to be and issue with the T-comm board - but thanks to you if I pull out that one cable at a time and find it is not the T-comm board but something in the panel I will not have to take the time to part this beast out - I should be able to work through the clock connections and could be a quick fix almost free - thank you!
I was finally able to use your method for a Sony XBR-65C900C. Following your suggestions, I was able to block the ribbon lines causing the issues with tape and now all issues of the 4K TV are resolved. No more black lines on top of the screen and no more out of focus intermittent problems. It is just like new. I did some try and error and ended up blocking around 5 lines on the right side ribbon. When I saw that all symptoms disappeared, I did not try to unblock any more lines. Thanks again, you are a lifesaver.
Thank you, thank you, thank you Mr. FeugalRepair Man! You just saved me from having to buy a new TV! Even though I had to cover up a number of pins instead of 1 (not nearly as skilled with an exacto knife as you are) I don’t notice any difference in image quality. I am telling everyone I talk to that they MUST subscribe to your channel! I cannot thank you enough for all the work you put into your videos and teaching us how to repair instead of replace. You are incredible!
I had to come back to this video for a reason.. my Panasonic led tv had same flickering issue they sent a technician from Panasonic but he couldn't repair it and said ill have to go for screen replacement which was costing me price of a new tv...also he told me that this tv has absolutely no value now if I give it in exchange for new tv.. I denied screen replacement and started searching on yt for solution and came across this video. I'm glad to say I've fixed the tv myself just by watching this video..their technician failed to do this simple fix. Thank you for making this video you saved my $$
Great job fixing it yourself!!
@@FrugalRepair thank you ❤
That was an interesting diagnosis. I've never seen this kind of process of elimination to fix horizontal lines on a large lcd screen. I'll probably never see this problem in real life again. It seems like a rarity but it's nice to know how creative one can be in finding a creative solution to pretty much bypass the issue. Nice job FrugalRepair.👍
Thanks, and thanks for watching!
My son and I fixed his Sony TV today with your trick. We both were surprised that it worked in the end. We had a bit trouble finding the Clock lines because they were labelled on one connector but not on the other. Finally we managed it and are very satisfied.
Of course you can still see some lines but only if you are near to the TV.
That’s awesome! Congratulations!
@@FrugalRepair I’m sorry, but I can hear your voice in your video but can’t see anything going on in it. Is there a function that went wrong in your video?
Donna the video has been up for years without issues. I'm sure by now you've realized it's a problem on your end @@donnahughes8409
I love how much clear info you gave in 10 minutes...this same amount of info in other videos takes 55 minutes with intros and people trying to display all aspects of their personality...and by the time you're done watching...you're exhausted and you decide to just buy a new TV and be done with it.
Thanks for watching and your encouragement!
never seen anyone explaining something with so many details. you are an amazing person thank you so much for your help.
Thanks for watching!
I am happy to inform you that I followed your steps and was able to stick the tape to get the picture back. The issue of fine lines was still there but I did not have your patience to find which was the faulty line to cover it with tape. The way you took out time to showcase the issue and resolution is commendable. I had 3 engineers who told me that the TV's screen was gone and it would be replaced by paying 50% of the TV cost, a small piece of tape did what these engineers could not do.
Finally, someone that speaks English explains with detail, what causes TV LCD panel issues. Louis Rossman would be so proud of you. Thank you and God bless you Sir!!!!
Thanks! Glad it helped.
Haha so true
One of those so simple I can't believe it works things. Spent an hour with a multimeter trying to find a short and failed. 5 minutes cutting tape and sorted. Thanks a lot, very intuitive solution.
Glad to hear you got it working!
Hi Lance
Is it still working good till date?
So glad I found your page! The material you cover is so interesting and I love the way you go about diagnosing and determining the issues. My dad used to repair TVs back in the 70s and he would include me and ask me to hand him a tool or something and I have good memories of that as a little girl! He would also use a mirror in front of the TVs so he would not have to keep flipping the screen around, which I thought was a really cool idea! Thanks again for the great info!
Thanks for watching and your note!
Thank you 🙏🏾 so much for posting this repair video. This fix worked on my Samsung UN55KS8000FXZA that kept boot cycling. You saved me a lot of $, and I feel so accomplished.
I did this initially and it did not work. I knew I had a good power supply, but was not sure about the main board and led panel. I went ahead and installed a new main board and no change. I did not find any burned resistors on the led panel. Went back to scotch taping along the 2 connectors on the main board. Tried a few different sections and then all of a sudden, voila!
For anyone out there with a Samsung and who has tried almost everything, try the scotch tape method again on various sections. You may get lucky! It’s worth a shot and costs zero dollars!
Brilliant. Just found you via the solar panels. Quality, like how you point out what is on the circuit boards BC I have no idea
I garbage picked a Toshiba 50” 4K with built in Firestick manufactured in 2018. I followed your video because the entire screen had horizontal lines. One side was good. I used the scotch tape on the other side slowly removing tiny strips with a exacto blade until I had a beautiful picture. The tv works fantastic now.
Thank you for your help.
Wow, that’s a great story! Congrats.
same here, 55 Hisense. Gonna try the tape tomorrow morning. Mine was alternating good to bad every second. I think it changes direction every second?
Wow, I learnt so much in so little time. Thanks allot. I used to say it next to impossible to be fixed when the screens get like that but now I have a different perspective.
Thanks man.🤜🏾🤛🏾💯💯💯💯
You are one smart guy! Makes me wish I was still in the trade and learning more!
Dude you are amazing. I have never seen anything like it.....I have learnt so much from this video. What an eye-opener.
Thank you for your kind words!
I've recently subscribed to your channel and really enjoy your content. You are very good at giving education on how to fix different projects without spending a lot of money.
Thank you for watching! Much appreciated.
Thank you very much for this informative and precise education.
I nearly gave out a huge amount of money for a replacement of my 55" WebOS LG Tv screen.
I got it fixed following the information and guide.
Thank you very much and God bless you.
This is fantastic, exactly how DIY TH-cam repairs should be, easy to understand and undertake. Thank you for sharing
Thanks for watching!
Great instructional video. Excellent and Intelligent troubleshooting skills. One of the best I've seen on youtube. The prior tech; as most people, have no such wisdom to isolate the problem to the suspect board onto the component level. They swap boards to no avail. then discard the entire system into our landfills creating a toxic disaster. Nobody takes their time to analyze the problem, research online of known defects, recalls and/or engineering flaws let alone a circuit roadmap or schematic for your specific brand and model We are a throwaway society as we would rather replace than repair. Pay for things twice out of convenience rather than DIY. The steps in this video are priceless: cause and effect, isolation, disengage, test one side by elimination, abnormal heat dissipation by thermal imaging, etc....just brilliant. I can relate with the author of repairing things that are practically new. I'm more into the "old school" vintage electronic goods of yesteryear unlike the throwaway electronics we have today. You buy a new TV. It goes out in less than a year. Its absurd as a consumer but great for our economy. Back when America meant quality, those golden years are long gone !! . . ,
Another example of technology mover backwards. I'm glad that I'm not the only one that finds it totally unacceptable to litter landfills with our disposable toys? E-Wastes are buried or incinerated in landfills where their toxins pollute our land, air and water. Most of the time, they are sent to developing countries where workers extract the precious metals from the discarded electronics. Workers on E-Waste sites are paid an average of $1.50 per day. No wonder the Planet is rebelling and hitting us with powerful storms, earthquakes and volcanic eruptions, trying to get rid of this cancer called "Humans".
Whaoooooooooh amazing.
Didn't know that.
Learn it today.
May I know how these knowledge come to your mind.
Or how you figured out these tricks.
Thanks for sharing. 😊
Great video i love watching people that explain everything and understand it all im so happy that u have a part 2 that goes more in depth cause i love that stuff heading to it rn thank you very much keep up the great videos !
I will definitely try your tricks repair in our tv when i go back to philippines. Our tv had the same problems. Thanks in advance..new subscribers here from bahrain 🇧🇭
Thank you for doing this and for a great detailed video on these kinds of issues. My TV (Vizio m502-b1) seems to do similarly to the darkening screen, only the vertical lines appear all in the middle, and by the bottom left corner (where the TV power button is), it seems brighter in that corner. I actually tested the ribbons and it seems like it's one of the ribbons causing the problem, so I tried taping (though I don't have a way to test which prongs nor have an exacto to trim precisely). It helped a bit but still has some glitches (much better now though than it was). Do you think that this is due to a bad T-Con board, or bad pins on the ribbon? I guess my question is, would you replace the T-Con board, the seemingly bad ribbon, or the other chip where the ribbon connects to the panel?
It was great bro! Nice demo! Watchiing here from phillipines! God bless!
Thanks for watching!
Excellent information and knowledge. You were able to help me restore a 55 inch Vizio that I thought for sure was a goner. It had an array of red, pink and black vertical lines covering the whole screen. I was worried both panels might be out. But following your detailed steps, I was successfully able to diagnose the faulty clock line and block it.
Thank you! Money saved and felt good being able to fix it and also learn something new.
Congrats, that is great to hear!
Thank you so much! My TV was a bit different, so I had to do a little bit of trial and error for how many pins in the tape went, but it eventually worked and saved me a lot of money that I absolutely did not want to spend!
Cool repair, Rhys! Can’t wait for the next part!
Thanks, I'm working on it! =)
You, Sir, are a freaking legend. A friend of mine wanted to get rid of his 55inch Samsung-TV and gave it to me. I just taped it and it's working like a charm, even without any lines or loss of color etc.
Congrats on the repair!
I wish I would have seen this video a year ago when my 70" samsung did this. I knew I could fix it but couldn't find any info. I came across another video of a guy doing this and tried it. I tried it an it worked although I didnt have much info on narrowing it down or any details like you shared. I appreciate the info and need to take the tv back down and do further diagnosis now that I have the info you shared.
Pretty cool. I wish I had found your channel before I threw out a TV a year back. It kept popping a chip on the TCom boards I put in. I suspect one of your videos would have helped me find the culprit... alas, I gave up. Nice video explanation. Thanks.
many thanks i fixed my LG TV today with your great help , thank you so much
That’s so great to hear! Congratulations.
Excellent work and explanation, hopefully you are inspiring individuals to TRY and fix electronics/ merchandise instead of adding perfectly good and fixable products to landfills. Thank you very much.
Thanks! I hope that I can help give others the encouragement to give it a try.
After 2 hours of work with this perfect video a fix my horizontal line problem on a lg led tv. You teach one more thing to an engineer. Thanks a lot.
That's awesome to hear! Congrats on the fix.
Thank you so much for being so dedicated and kindly giving us your wisdom
That is one to bypass the panel issue. Good Job!
Thank you!
wow...thank you very much for this hack. i was about to give my 55 inch Iffalcon smart tv as scrap. i did just liek you and put tape on specific lines like yours...even though the picture is not sharp and has soem lines still it works well. thanks again...
Great job! That’s encouraging to hear
Your advice saved my TV! 13 month old 55" TCL Roku went black on Christmas Eve of all days, 28 days out of warranty. I tried all the resets to no avail and was looking at replacements. Then I followed the isolation procedure outlined and found by disconnecting the right cable half the screen came back. While the clock lines wern't identified with anything like "clk", I isolated lines 2 - 9 on the left side and one by one exposed the connections. When I exposed the connection on pin 4 the full screen came back. Pin 4 was the only one I had to leave tape on and the TV is saved! I can't find any visible issues with the picture or performance. Thanks so much!
Wow, that’s great to hear! Congrats on getting the picture back.
Frequently in my city we have facebook curb alerts. it’s pretty common for neighbors to put free items at the end of their driveways. I was running errands and I saw this LG 4K 75 inch TV at the end of my neighbors driveway, It was free.I saw that the LCD wasn’t cracked, immediately knew that whatever was wrong with it had to be small. Took it home, watched this video. Understood everything that was said. Followed these exact steps and I now have a working TV. Your information is extremely helpful, didn’t need to take it to a technician, I became the technician. Thank you so much!!!
That’s a great story and congratulations!
thank you again. its working like it just came from the store! LOL! @@FrugalRepair
You are a genius!! WOW awesome job
That was a surprisingly awesome process, bud. In stead of thinking outside the box you just taped it up! Kickass never considered that technique. Subbing and studying the wys of your force.
Haha, thanks!
Thank you for this tip! After some trial and error, I found the corrct pins on the ribon cables chaining the 3 seprate lcd PCBs together. Saved my 65" TCL from the recycle bin.
Congrats! That's awesome to hear.
I am not a technician... but i love to know more about the process of tv repairing that i can be done.... thank you for this tip...
I've learned a lot from this video. Thank you sir!
Glad to hear it!
Where have you been man? We miss your great content!
I had some family health situations I needed to help with over the last year. But thankfully things are much better now. Thanks for the encouragement! I’m working on part two right now. Let me know if you want to see anything else in particular. I’m planning on some videos about solar after this next tv video.
Wow, that was an amazing diagnosis Dr!
Thanks for sharing! I enjoy watching people like you solve problems!
My LG tv has a dark shadow on the left side of the TV!
Lemme know if you have any possible solutions!
Thanks a million!
It’s easy to tell that you really enjoy what you do!
Thanks again,
Your friend,
Barry
Thanks! A dark shadow likely indicates a faulty backlight. Try turning the brightness down on your screen to like 5-10% and restart the tv. The backlight might come on in that area. It also might not and you have to go in and repair it.
🎉Hi, Keshi from Nigeria, just fixed my scanfrost 55in tv after watching your video. You are the best. Thanks
Congratulations!
I have a 75” TCL that had this same problem. It has two 60 pin connectors so it took a little trial and error but I was able to fix the TV and save buying another one! Thanks for posting! Worked perfectly. I wish I had a pair of magnification glasses to assist in repair but I was able to muddle though. Thanks!
Wow, that’s awesome you got it working!
Gary i cant even find the clock lines. Im lost. I have a 55” tcl tv 2017 half of the screen is dark and fuzzy. I also have two 60 pin connectors. Any advice
Hi do you remember what pins you taped up i have rhe same issue with my 75 inch tcl thank you much appreciated
Gary any chance you see this and can respond? I have a 75 inch TCL 6 series with no picture but can’t find the clock lines on the board. Are they labeled something else?
@@martinnoah9716 if you watch the video he shows you where to look. As I recall it looked just as shown it video. The clock lines are marked on the board and lead to the ribbon cable plug in. I did just as described in video and unplugged one at a time and determined which side was causing problem. Then tapped ribbon cable and started removing tape one click line at a time. Very tedious and time consuming but I did determine which pin was the problem and the TV is still working. At times I can see the line that is not illuminated . Only when the background is light colored. Hope you figure it out. As I stated it’s not hard to do just very hard to see do to the ribbon cable pins being so small to the naked eye. If I did it again I would use magnifying glasses.
Thank you sir! I love learning from you.
Thank you for your encouragement!
This was the best idea I ever got on fixing a TV. I was able to fix a Samsung 70 inch my mom gave me before she threw it away. Thank you so much!!
Thanks for watching!
That’s what we all did living in the Soviet Union, we fixed things. 👏👏👏 bravo! We need more of the fixing and less if throwing away things
That's really clever, i wish i could find a TV to attempt my luck.
Here's hoping to more of these videos in the future
Thanks for watching! My wife found this one for me in a local Facebook group she is in.
Man I just fixed my tv following what you did the shit really worked.. I was about to send it with the trash truck.
Thanks saved me a lot of money..
That’s awesome! Great job.
Thanks for this tutorial you helped me save my 8K tv. All that is wrong now is a small line in the top left corner of my tv, every where else looks amazing again
Glad it helped!
Great detail seen many videos but this explains perfectly now I understand what to do and I am ready to fix my tv.. Thanks.
Thank you very much for sharing your in knowledge. I used this to “repair” a 60” Sharp TV. I had already replaced the power board and thought it was the light strips. I prices replacement by a pro at $350, so I went to TH-cam to see how to it myself. There I found your video. Long story short, there was no jumper map so I just went to town. Saw varying results. After 4 hours, I was wrapping up for the night and took all the tape off. Somehow, everything works perfectly. No tape! Went from a dead screen with sound to tv that seems brand new. Any idea why or how that could be? Thank you again.
Thanks! No, I don’t know why. It may be heat related or pressure on a cable or a connection issue.
Corrosion on a loose connection. Sometimes with lots of electronics you can reconnect plug and it scrapes off the corrosion for a fresh new copper connection.
wow, thanks for the sharing.
Thanks, I just followed your video and solve my tv issue!!, still working on the horizontal lines and I hope will find the short-circuit else live with that, thanks a lot and keep up your good work man.
Your tape trick worked like a charm on a 75" tcl tv that I was given. I had put money into the tv before I came across your video. Would it be a problem with the t-con board if the tape worked?
No, most likely if the tape trick works then the issue is on your lcd panel.
I have nothing to say.sir nice interpretation.god bless..
Wanted to come back to this video and say thank you. Was able to fix the tv. Great job.
awesome, thanks for letting me know!
Awesome! I have been trying to figure out what's wrong with my Samsung after 1 year of use. That black cloud is what's happening and now I will try to repair it. Thank you!!!
I'm starting to get horizontal lines which are flickering across the top and bottom of my screen 😔 hope I can gather the courage to open it up and check it based on your advice 🙏
hello, sound like you having the same problem as mine. Did you fix it?
Sounds like a faulty tcon flickering lines are usually caused by tcon but solid horizontal lines as shown in this video are lcd/led panel issues
Blessings,,thank you I will have to try that one
Let me know how it goes!
My TV just went blank don’t know what to do 1 year any advice please
Did this trick and it worked for me. Ended up with three pins blocked. Now the picture isnt 100 percent but it’s a useful tv again. I’ll probably put it outside on the porch.
Congratulations!
I can't believe it, but this worked. We changed out the main board and T con board due to sudden vertical lines that appeared on the screen, but nothing worked. When I followed the instructions on this video, the TV suddenly started working. Thanks Frugal Repair!
Congratulations on getting your image back!
Therefore the problem is the ribbon jus asking.
That's so interesting! I'm always learning stuff related to electronics and you are one of my new founds! Thank you!
Thanks for your encouraging comment!
Successfully fixed my 55''sony led TV flickering problem
Thank you sir.
I am from Kerala, india
That’s awesome to hear! Congratulations.
Could you please share your fixing experience with us
Great explanation. Having an issue with thin color horizontal lines on my TV. I actually had this same TCL TV with the same issue. Wish I would have found this video before trashing it after trying to replace all three board in the TV....
Thank you thank you thank you I fixed my TV all because of your videos all❤💯💯
Would this technique work on Sony X9507G Bravia? Because my tv isn't showing any display/pictures but has backlight, it turns on, it also produces sounds and audio. The only problem is display/pictures.
I don’t see why not. Give the isolation technique a try and see if it points you to a screen issue or if both sides behave the same, a tcon board issue
Thanks for all these tips! I'm facing an similar issue. My lcd monitor has some horizontal lines (on top the windows taskbar) that appear with a periodicity of about 6s (3s with lines, 3s without) . Do you think you can give me an extra tip before I unscrew everything up? I ran an autotest and the source of the problem is the monitor for sure, not from the cables or the PC.
You might only have one video cable to the lcd which would make the isolation technique difficult. This hack requires redundant gate (row) signals on the lcd design. I probably can’t help you much further without being there in person to explain how it works.
@@FrugalRepair Yeah. I don't think I'll find a redundant gate on this device, but I guess I'll still open it up when I can spare the time. Thank you for your kind response. Cheers from Brazil.
@Frugalrepair I love DIYing ever since I was a kid, I just don't have a lot of time for it anymore and the space to work on stuff to dig deep into some of the repairs I attempt. ( family life happens if you know what I mean 😆 ) I hit like and subscribe as soon as you started schooling us 🤗😆
Holy shiiiit this really works. OMG. Thank u so much🎉🎉🎉trying for 2 hours and it worked. Amazing. Never saw anything like this on TH-cam.
Congrats on your fix! And thanks for letting us know.
Dude, subbed just because of the fact your face is mesmorising in a good way
I'm to the point you're showing us, but this set up is a little different.. we need people like you on call! Lol sure would help
That was wonderfully instructional. Thank you for posting it.
Wow! Among the chaotic plethora of DIY television repair videos, there is a diamond in the rough. A simple 👍 is a tragically oversimplified accolade for the numerous things done right in this how to video. From the omission of unnecessary prologues or title intros created on a win 98 video editor to the excellent walkthrough narration (that clearly reveals strong ethos and logos without completely losing the novice in a sea of jargon), this video is a welcomed reprieve. Although my TV was suffering from different symptoms than the one in this example, I was captivated by the level of professionalism on display. This is a shining example of what a DIY TH-cam video should look like. It is a benchmark. Furthermore, it should also appear under the category for "How To Make Your Own DIY TH-cam Vid." Did I mention that I gave it a 👍?
Thanks for your kind words!
Simply excellent!
Thank you!
Ive got a TV with very slight lines at the top visible on brighter images. I can't wait to give this a go.
Let me know how it goes. If this video doesn’t help you hopefully the next one (part 2) will.
Great video! Thank you for sharing! We have a TV with a black screen that we've been holding onto for over 4 years and now I'm going to open it up to check things out!
Hope you can figure it out!
@@FrugalRepair Thank you sir!
That was awesome
So many tvs are disposed of and can be easily fixed. I'd like to see more of when the actual LCD is damaged
Thanks! Do you mean if the lcd is cracked? Unfortunately, if it is cracked you can’t fix it. If the polarizer is scratched or damaged there are some tricks to mask the damage.
That is amazing!! I do have a 55 "TCL tv also ao far so good.
Thanks !
Great job 👍 where did you learn that trick from?
Thanks! I learned about how lcd signaling works and this concept of blocking a clock line from a bunch of different places. Important clues came from an ebook on lcd repair, I did some online research on how lcds work, and some deduction (my degree is in computer engineering).
@@FrugalRepair Hello, great Content.. Can you us given the link from this ebook? Thanks so much
@TampaTec - your channel has similar issue vdo and you too fixed this issue with masking tape :-)
Thank you sir!it's really a big help..God bless.more power...
he learned from the benjamins 💸💰💰💰
I am soooooo happy that I found your video. You taught me how to fix my tv. I really think the tape made the color look more vibrate. Thank youuu for doing this video
Congrats on the repair! Great to hear.
Holy cow this totally just worked on my Visio M50- C1!!
I wasn't as precise, just put a small piece of tape on the side showing a blank screen, and had to move it around a cpl times before it worked. But I'm back to a perfect picture now. Thank you so much for posting!! Saved me a lot of money.
Congratulations!
