Can you even buy replacement LCD panels outside USA for consumer LCD/LED TVs along with the board controller and replacement remote controls in single units without ordering 25-50-100 off them from a vendor in china ?
I have a question I need help on fixing my Samsung tv it truns on the shows a white screen and turns black it has sound but no pic we got this out of a old lady's house that got caught on fire but this tv was in the far back room can u try and help plz
Hey friend, how thick is the metal sheet, that is used as the backplate in TV? Are all of those same thickness or bigger TVs have thicker plate? I mean, does a 43 inch LCD TV has a thinner metal backplate than a 65 inch LCD one?
Hope you see this, just want to personally thank you for teaching me how to do TV repairs, After finding a 42 inch TV dumped by the bins in my local area i decided to take it home and try to fix it myself, after watching alot of your videos i finally found out what the issue was (it was faulty LEDs) so found a site that did replacement LEDs for the model i found dumped, im glad to say after following your steps i now have a TV that works and for $30 (cost of LEDs) instead of the original price of a new model which was $399
@@TampaTec that would be awesome! Do you know of any tools that would help removal of a panel to service the LED's below? It's fairly difficult to service a larger TV.
@@davidbasara6162 If you are talking about the main front panel.. Suction cups are the best way I've found to pick it up without a lot of flexing and not as much risk of breaking it lol
I just want to say that you are the best in explaining how to fix just about any tv. I love watching your youtube videos. Keep posting them. They do help a lot.
I just want to say thank you. We have five kids and was gifted a 65 inch Samsung tv just before Christmas. It wasn’t new but boy my kids love it. It was a dream to have such a nice tv for family movie night. Just last week the picture went dark. I was lucky to find this video and by following the simple instructions I fixed my tv. I was so proud of myself because I’ve never fixed a tv before. Thank you again and my kids thank you too it’ll be movie night once again this Friday. PS it’s kinda hard to find parts these days
My husband & I are going to try & replace the T-con board. Will have to find a parts source here in Ontario, Canada. This tutorial you made is an enlightening& sobering knowledge that simple folks like us (well my hubs is an industrial maintenance millwright) can fix it for less money that some tv electricians are charging here ($180 to $300 CAD). Will let inform you if successful. Thank you.
well thanks to you, i fixed my tv! tv started getting washed out, then finally when totally white... found a t-con card on ebay for 20 bucks, installed it and good as new! not bad for a 10 years old tv!
I always watch your video's and always enjoy them, I learned to fix TV's back in the 70's ,there so much different now, these days I restore old TV's & Radio's,, I love your work.
Hello. I couldn't see where you were putting your probe on the input side of the TCON board. Could you tell me which pin you were testing for power? Also, how much power do you expect to see? Thanks, Michael
I'd like to see the installation of the replacement t-con board just so I can can get the "satisfaction" of seeing it turn on and function as intended. Love your videos !
I have a black screen on my Samsung curve 55” and trying everything except for taking apart and still not fixed. After looking at your video I’m going to try to take it apart. I only bought it 3 years ago. I’m very disappointed it didn’t last longer. Do you it could be something simple? I have a background in electronics engineering but never worked on a tv before. Thanks for your help.
Hi great video's, I'd like to see more on trouble shooting surface mounted pcb's and fixes please. keep on with the great video's. yours is the only go to channel for me learning a lot.
Great video and thanks for sharing. My tv is has a black screen and sound, but not 100% black. If you look close in low lighting it blinks about every 2 seconds. Could this be caused by the Tcon board? Thanks and kind regards, TJ
Yes but turn off the lights in your room then use a flashlight on the LCD screen to check if you have a dark image. Press menu or vol to display something to see. Get tv parts at shopjimmy.com or Electropartsonline.com
Howdy, I have a 60inch Samsung that for some reason is kicking my butt. I have no LED’s coming on at all after changing two of the three boards…power supply and lower center with two ribbon connectors “T-Con”that go the LCD screen. I didn’t think they needed to be connected to at least have the led’s on…I did change those as well. The only board I didn’t change is the source input board. Any ideas? Thanks, Rafael
This is helping me understand the inside workings. Just to get some clarifying, my screen on my Samsung UN55H6350 is super dim. I still have a very low lit picture that you can barely see. Sound is fine and all functions appear to be functioning. I have not opened up the TV yet (it scares me to a little) but I cannot afford a new TV. I am thinking it could be the tcomm board. Your thoughts would be really appreciated
Thanks for the tutorial. I have repaired many tube televition but about to repair my first Led LG television with sound but no picture. Thanks from Nigeria.
Need to check the voltages to tcon and backlight. It can be bad led backlight strips. If happens on all TV inputs and brightness flickers it's probably bad backlight circuit if the color picture flickers not backlight then can be tcon, or main video board or power board not sending proper voltages. Troubleshooting narrows down the possibilities.
If you were to unplug the TV is there any kind of stored energy somewhere/ capacitors that could still shock you? I'm supposed to open a computer tomorrow and I've seen people wearing a grounded bracelet that's clamp to the computer. I don't have one of these so I'm just going to go in and do it. I'm an electrician licensed but when it comes down to these microscopic TVs and computers I don't really mess with it. I am seriously just starting to get into it now so I know absolutely nothing about it.
Hello mate... If u remember back a month or two I commented that I had a Samsung with this problem but mine is not Backlot. I told u that my friend is giving me another Samsung with broken screen n good internals.. U said let me know what happens I still not collected it yet. Great upload.
My Samsung smart tv turns on but has a black screen, if I disconnect the right ribbon from the t-con board only half the screen works. Any suggestions?
Just liked and subscribe. I've got a Samsung and the screen flashed a few times and went black. I can still hear it. I took the back off and plugged it in and I don't see any back light like what you have in this video. Would that be the led strips bad and do you have a link to that?
I have a Samsung UN50H6350. Sound but no picture. If i disconnect the power board from the main board all of the led backlights come on. When I reconnect the power to the main the backlights go off. Do you think it's either the main or t-con board? What should I check next, voltages? thanks jeff.
Hello Bro, i just want to thank you for all the videos you have made. It is very helpful....please am having a vertical lines on my tv and i dont really know if my T-con Board need replacement. i will need your assistant in other to make the right decision. thanks
good video. i have a 65 inch samsung that is black. the back light appears to be working. can you give me more info on the voltage that should be present on the drive board for the leds? as well as i can tell i have 6 volts on pin 60 and 1.3 volts on pin 1. is this close to correct or does this not meet specs?
Dear Tamptec I have a 39" Samsung Model UN39EH5003FXZC tv. Tv had no picture it had sound. It had bad LED strips, so I replaced them.I checked the led strips and they are all working fine. What should I check for next?
hi tampatec , im writing to see if you can offer me some advice please? my samsung tv is now exactly in the same state of yours is, this has happened after i took my tv apart to fix the problem of the led lens caps had fallen off and i had the white circles, i was as careful as i possibly could be and after building back my tv back up im left with no display, very like what your describing on this tv, is it possible i have ruined my t con board? thanks david
A very good video and presentation, the information revealed is very important for us that don't know about fixing Tv's. Loved it, Thanks brother. New subscriber here. Lets stay connected. 🙂🙂🙂
I really your videos and am learning so many things. Well I have a Samsung 32inch. Only half screen is opening. Well I am thinking may be some problems with the strips voltage ⚡ is not going or some issues like this. Not yet open it. But will check it out soon. Thanks for sharing. 😊
Hey I do electronics as well and I've got a curved Samsung TV that I changed tcon and main board and still gets a black screen so My conclusion is the psu pcb and has an additional driver board on it for the tcon, have you ever worked on those tvs? The model number is un55h8000af
Hi thanks for your information about tv I have 60 inch LG tv two years old run out for warranty it has pictures and sound but from top to half on screen is darker than the bottom screen what you're suggesting thank you very much for your helping
Hi, i like your videos, i have a 5 year old Sharp Roku TV that has sound but no picture, it comes right in the beginning and goes off very quick, i opened the back, and turned it on the led lights go on and off very quick, i suspect the LCD logic Board T420HVN06.3 Ctrl BD 42T34-C03 (FT-5550T20C21-57L-000N6P-04701-04) What do you think?
My Samsung television (UN55KU6290F CJ05) does not have a visible T-Con board like yours. It has both other boards. I already swap the green board (main board) on the left and the issue still remains, Black screen, lcd works but no image. Suggestions would be great, i am thinking of changing power board but i dont believe that will fix the problem.
Ya think, this chode is hiding secrets that could possibly sink a LCD battle cruiser. Hmmmm....think of all that could have been done with this fragmented tutorial. Adding part 2 ,shows the depth of which this this"no. 2" will go to pull the shades down before you begin to succumb to the power of the blacklight. Something is controlling the weather causing a blackout. Ok, I'm out!
Thanks, I used your testing examples to try to see why my LED TV splash screen would come up then go black. Never lost sound and all buttons would work. So I figured the T--con board was bad but no one had the part in stock or knew when they would get one! So I trashed the TV.
Hallo can you help me: I have a Samsung UE55MU6179, that makes the same on/off and no screen. When I pull Ribbon 1 from Mainboard to screen, it keeps on with backlight but no picture. Wehen I put ribbon 1 back in and pull ribbon 2 from Mainboard its the same, tv keeps on with backlight but no screen... I think it is the Mainboard, what Do you think? Thanks a lot
i was recently given a Samsun 40" lcd hdtv ln 40a630-1080p. for about the first 20 minutes after you turn the tv on, there is no picture on the left side of the screen. after about 20 minutes it suddenly comes on. or if you put it into sports move you can see the whole picture for that 20 minutes. Any idea what could be wrong with the tv? thanks for your help
I wish I could post a picture, but I have a Samsung 65 inch, and I bumped into it and now there is one white line going down the middle of the entire screen. do you think replacing the tcon board will fix that issue?!
Any way I could ask you a question relating to the video? I have Samsung tv like the one in the video. My question is why does the black light not turn on when then power board and logic board connected? I unplug the cord running from the power board to logic board and all the backlights come on. Pls help!!!
Hello I did comment in another video today my TV the back lights come on then they flicker and go off I only have sound but to start with the TV is fine any ideas what this found be thank you
I've now had two Samsung TV's go blank on me (Black Screen of Death). I threw mine away. The screen going blank seems to be a consistent issue with Samsung products.
HI. What can cause same power problem, like blown capacitors? I have Bush 24" with flashing standby blue light ON, after every 40 flashes trying to reset, some time can get ON, then is fine, till get Tv OFF. Then again flashing. All capacitors are OK, power and main board is on same board
i had a problem with my kdl-60nx810 sony I couldnt determine weather the tcon or the mainboard is the problem. i tried removing the cable that goes to the mainboard and the tcon still has the supply then I turned it on, then the screen turns to like color mode testing which displays color such as red green blue and gray and some shadowing. now I'm confused which one to change the mainboard or the tcon.
I have many videos on component level repair please check my Repair playlist but this video is for everyone that just wants to fix their TV. I have another TV I'm working on that needs parts in a power supply, that video coming soon.
I subscribed a while ago just because I like how informative you are and I love learning. Just so happens after I got back from a deployment last night, my Samsung TV UN32EH5300FXZA went black after 10 minutes of turning on. I took it apart and noticed my backlight won't turn on but I have a picture on the screen. Any tips you could give me would be great brother.
Hey tampatec, I have a Sony kdl-46ex400 with no picture or sound, green light only when you power up. I followed your video and ordered the main board and swapped it. I got really happy to see the tv turn on and show me the language selection screen... a few hours later tv is back to no picture and no sound :(. Can you please help?
I've got a few flat screen LCD and LED tvs to take a look at. A long time ago, before I knew much about them.. I made a mistake. I took one apart... I'm talking about the whole screen to see how it worked and the connections to it. I must've got the panels or the connections wrong lol. before then the screen was just going dark on the edge, that's all. Now it looks like colored lines and distorted colors everywhere. But it does light up lol I haven't touched it since. Got any ideas?
@@TampaTec leaving one side of the t-con hooked up and then checking for a pic, then doing the opposite half would give you more idea if it is the t-con or panel. yes the panel can drag your t-con voltages down.
Hi, thanks for the video. I changed the tuner setting in the secret menu to auto and changed EU to Switzerland. Since the restart I have the smart TV logo then I get the same blue screen and then the TV turn off after few second and turn back on. I can't go to the menu or source. The screen is exactly like yours after the smart TV logo. I did all hard reset I found but can't find a solution. Thanks for your help. I have the Ue40f6400aw smart TV.
so whats the output voltage from the t-con board supposed to read? you didnt show that. otherwise i have every issue that this tv in the video has.........
hi . i have a samsung 50 inch and half screen works when i disconnect one side of the ribbon cable to the panel. when i plug both of them in no picture at all on the whole tv. backlight is fine. what could be the problem? please leave a message. thanks
I have a tv where the entire back light is out. I can see the picture if I use a light to look through the screen so I know the logic board is good and the con board is good. I am now wondering if just one leg of the power supply is bad. Do they ever do the led strips in one line my series? I just n Ed to pull the thing apart and troubleshoot the power supply.
hi i have Samsung UN48J520DAFXZA (Version ED04) the problem no picture but has sound no light behind the tv no led light but in dark room i put flash light i can see menu display and video any solution
I have a 50 inch Samsung where the picture just dropped out one day as I was watching -- like a curtain dropping on a stage. Then everything was black. I tried replacing the T-Con board, but that didn't make a difference. Then I read one of the comments here about trying the output ribbons from the T-con board one at a time. I got one side of the screen (the right side) to work when I had the right-hand ribbon attached along with a white screen on the left side of the screen. When I had only the left-side output ribbon attached, the left side of the screen was black and the right side of the screen had black lines on white background for a short while, and then it, too, faded to black. I interchanged the ribbons to test the ribbons and got the same result, so I don't think it's the ribbons. Also, I tried both the new and the old T-Con boards with all variations of connections and they worked the same way. What else can I check? Thank you!
see tcon ribbon connections to buffers near the bezel, buffer boards are hard wired to the LCD panel check that, sometimes freeze spray can help locate problem areas.

Any idea what could be wrong with the tv? thanks for your help
I wish I could post a picture, but I have a Samsung 65 inch, and I bumped into it and now there is one white line going down the middle of the entire screen. do you think replacing the tcon board will fix that issue?!
Thank you sir my tv is back to life
Congrats fixing your TV
good information. keep it going
Any way I could ask you a question relating to the video? I have Samsung tv like the one in the video. My question is why does the black light not turn on when then power board and logic board connected? I unplug the cord running from the power board to logic board and all the backlights come on. Pls help!!!
Another great video. This was very helpful. Regards
I’m gettin a backlight, but no picture, I’m not sure I sound works. Any idea what I should do?
Hello I did comment in another video today my TV the back lights come on then they flicker and go off I only have sound but to start with the TV is fine any ideas what this found be thank you
nice video ,,very informative
I've now had two Samsung TV's go blank on me (Black Screen of Death). I threw mine away. The screen going blank seems to be a consistent issue with Samsung products.
HI. What can cause same power problem, like blown capacitors? I have Bush 24" with flashing standby blue light ON, after every 40 flashes trying to reset, some time can get ON, then is fine, till get Tv OFF. Then again flashing. All capacitors are OK, power and main board is on same board
THANKS BROTHER, saved me money again!
i had a problem with my kdl-60nx810 sony I couldnt determine weather the tcon or the mainboard is the problem. i tried removing the cable that goes to the mainboard and the tcon still has the supply then I turned it on, then the screen turns to like color mode testing which displays color such as red green blue and gray and some shadowing. now I'm confused which one to change the mainboard or the tcon.
Is there ever a time you will attempt to repair components on a board?
i.e. the power board might have a bad capacitor?
I have many videos on component level repair please check my Repair playlist but this video is for everyone that just wants to fix their TV. I have another TV I'm working on that needs parts in a power supply, that video coming soon.
I subscribed a while ago just because I like how informative you are and I love learning. Just so happens after I got back from a deployment last night, my Samsung TV UN32EH5300FXZA went black after 10 minutes of turning on. I took it apart and noticed my backlight won't turn on but I have a picture on the screen. Any tips you could give me would be great brother.
Hi can you interchange tcon ribbon cables on t con board. Switching them left to right and vice versa
If I have a black screen, no lines streaking, can I just skip to the ordering of that part? Is it like 80%-20% chance? I hope it's higher lol.
Hey tampatec, I have a Sony kdl-46ex400 with no picture or sound, green light only when you power up. I followed your video and ordered the main board and swapped it. I got really happy to see the tv turn on and show me the language selection screen... a few hours later tv is back to no picture and no sound :(. Can you please help?
I've got a few flat screen LCD and LED tvs to take a look at. A long time ago, before I knew much about them.. I made a mistake. I took one apart... I'm talking about the whole screen to see how it worked and the connections to it. I must've got the panels or the connections wrong lol. before then the screen was just going dark on the edge, that's all. Now it looks like colored lines and distorted colors everywhere. But it does light up lol I haven't touched it since. Got any ideas?
🤔Bad tcon ribbon cable connection maybe 🤷♂️
@@TampaTec I was thinking somewhere along those lines.
Hot hot hot. Thank you for all you share.
You said near zero Volts to the LCD, is it possible the ribbon cable to the lcd or the lcd itself might be shorted to ground?
hopefully not but it would read short to ground not a voltage usually.
@@TampaTec leaving one side of the t-con hooked up and then checking for a pic, then doing the opposite half would give you more idea if it is the t-con or panel. yes the panel can drag your t-con voltages down.
No answer?? How much voltage?/ In and out of TCon board?? Thanks=)
Please make this kind of Videos thanks 👍🇵🇰
Hi wondering how do you set up a wireless-nap/repeater/router
Hi, thanks for the video. I changed the tuner setting in the secret menu to auto and changed EU to Switzerland. Since the restart I have the smart TV logo then I get the same blue screen and then the TV turn off after few second and turn back on. I can't go to the menu or source. The screen is exactly like yours after the smart TV logo. I did all hard reset I found but can't find a solution. Thanks for your help. I have the Ue40f6400aw smart TV.
How much are theses boards and what the name of the company that sakes them one more thing who sales those testers are they just fir TVs ?
Tcon board controls TV LCD screen. Shopjimmy.com or electropartsonline.com
Lucky I found this. My Samsung has sound no pic. I only see the pic of I shine a flashlight close to it. I assume it's the Tcon board?
so whats the output voltage from the t-con board supposed to read? you didnt show that. otherwise i have every issue that this tv in the video has.........
Grandmas tv Samsung model number un39fh5000 sound and little red light comes on but all dark. Flash light test nothing can be seen. Any suggestions
Thank You so much
hi . i have a samsung 50 inch and half screen works when i disconnect one side of the ribbon cable to the panel. when i plug both of them in no picture at all on the whole tv. backlight is fine. what could be the problem? please leave a message. thanks
I have a tv where the entire back light is out. I can see the picture if I use a light to look through the screen so I know the logic board is good and the con board is good. I am now wondering if just one leg of the power supply is bad. Do they ever do the led strips in one line my series?
I just n Ed to pull the thing apart and troubleshoot the power supply.
Check my repair playlist I have a few videos on led backlight repair.

Is it possible to find which smd is blocking the power to the wire?
I have a 50 inch Samsung where the picture just dropped out one day as I was watching -- like a curtain dropping on a stage. Then everything was black. I tried replacing the T-Con board, but that didn't make a difference. Then I read one of the comments here about trying the output ribbons from the T-con board one at a time. I got one side of the screen (the right side) to work when I had the right-hand ribbon attached along with a white screen on the left side of the screen. When I had only the left-side output ribbon attached, the left side of the screen was black and the right side of the screen had black lines on white background for a short while, and then it, too, faded to black. I interchanged the ribbons to test the ribbons and got the same result, so I don't think it's the ribbons. Also, I tried both the new and the old T-Con boards with all variations of connections and they worked the same way. What else can I check? Thank you!
see tcon ribbon connections to buffers near the bezel, buffer boards are hard wired to the LCD panel check that, sometimes freeze spray can help locate problem areas.
make sure tcon board is correct version and from reliable source like shopjimmy.com or electropartsonline.com
@@TampaTec What should I check on the buffer board? Also, Freeze Spray? Never heard of it...
Nice bro... but why not to repair the t-con it self to reduce the repairing cost, thanks
The tcon board costs only $17. electropartsonline.com
@@TampaTec thanks for reply👍
bro pls show the meter reading thanks, continue video bro.
Thanks!!
I love electronics.
Part 2 please
