Had the same issue as you, your guide for troubleshooting helped me repair my TV. Thanks a ton!

You're a gift from the sky bro! You have the closest idea that helps me save my TV. I used electrical tape to randomly cover 4-5 lines in the lower right ribbon cable. Thank you so much!

Thank you soo much! I already had electrial tape and was about to fork out for a new power board but after seeing this video you saved me money! I'm proud of myself for fixing it rather than getting a new one. mines the Samsung TU8000 and only 3 years old too! Thank you!

Great to see this. I had my Samsung 55" tv for about 4 years, when the tv started to shut down and not booting up anymore. I used a piece of tape to isolate 3 lines on the left Flex cable, and suddenly the tv started up without any issues. I also do not see any lines or faulty colors in the screen. Problem isolated👌🏼! Might sell it because I already bought a new tv when this one broke in 2021😂. Thanks!

This video saved me From buying a new TV thank you so much you are a hero

Great video. I scrapped a 55" only 2 years old because of this issue. Still got a 50" doing the same thing. Your video has given me hope that maybe I can get a better picture out of it before I give up. Samsung is not my favorite TV to repair as a hobby now. Thanks

My Scamsung TV is having similar issues. It suddenly keeps restarting. Already pinpointed to the strips below the LCD screen, so probably something shorted within the screen itself. It baffles me how many Scamsung TV's are having the same issue. Probably some sort of degradation of the substrate in the panel. TV is just over 3 years old. The way companies sell us stuff that break down juuuust after warranty is saddening. Thanks for the video, I'll give it a go tomorrow!

Great, thanks very much. It was fiddly, but I used a hand free magnifier and scalpel, It worked a treat.

Thank you so much for the video. I have similar TV and other videos on the internet weren't helping. I'm still figuring out the correct port to block but the picture is up with 95% clarity already.

Thank you so much, that video helps a lot. Had the same problem, but managed to fix it with your video👍

Great video! Thanks for the help!

Thank you so much for your video. Helped me to fix theTV :)

Thanks!!! Took a bit but was able to get my 70” functioning again. It just has a line that will always be there. The kids like the upgrade from a 42”. Trying LG this go around. The 70” had three boards on the bottom with two of those connectors. Took a while to figure out which one was bad. Use your phone camera zoom. Only way I could get a good view of those small pins.

I dont know much about what makes an issue become a recall. Samsung should definitely put out a recall for this. I bought from Samsung a 50in Q60 flat QLED on November 16th of 2020. Its just been sitting in my back room for a while. Your videos will be a huge help when i start to fix it this week. Thanks!

Really appreciate the walk-through. I got my tv working now. Only issue is the color red is slightly faint but it will do. Other than that no lines on the screen. I have a scamsung 70 inch as well. The problem is definitely a trend for this model. Thanks again and keep doing you Brotha!!!

Nice I fix a un55nu7095 model tv where ck2 on the driver board was causing the set to come on and off .thanks allot for sharing your information.

Greetings from Puerto, great video, thank you for sharing with us. When I saw this video, I thought this is the person that can help me out with my problem. I am replacing the LEDs and while removing the plastic sheets (a soft and a hard ones) I forgot the order in which they go the TV is a Samsung model UN5OM5300AF. Up to this moment 01/12/24 I still waiting for the LED strips to arrive home. If you can help me, I will be more than grateful. Respectfully, Wilberto González

Thanks for this video! I fixed my 50inch with normal tape over 4 lines. Only 3mm of the outer lines are not working.

Great video, thanks. My 70" Samsung failed the same way. I noticed over time, before it failed, that the picture was becoming patchy. Would only really notice this if there was a program where the screen was mostly white or one colour. It was getting steadily worse. Don't know if it's connected to the final failure. It's not the first Samsung TV I've had that's failed this way, gone patchy. Anyway I have no confidence in Samsung TV's anymore and will buy a different brand to replace it. It is only 3 years old.

Thank you for your sharing experience.I have Samsung 50 inche.When one of cable Led drive from T-con take out half of picture is there and half of other is white . I appreciate you send me some advice .If there are use both of cable led drive have connection all picture is white

Thnx!

Great educational video! I have a similar problem with a 65-inch Samsung TV. Cycles on and off with a Roku logo for about 1 to 2 seconds. I purchased the power supply board, however, the same issue. I followed your instructions on disconnecting the mainboard from the ribbon cable, however, the back LED lights do not turn on like your video shows. Any ideas of what I am missing? Mind you that the power supply board is a new board I purchased.

Hello, my 58" TV turns on/off. I went ahead and disconnected the motherboard above power supply. The backlight are good and power supply is good too. Now if I disconnect the white strip connection from the motherboard, the backlight stays on but no picture and no sound. If I reconnect the strip and unplug 1 drive (right/left) , the backlight stays on aswell. If I disconnect the middle "power button" from motherboard, it does the same thing as the beginning. You mentioned that no sound from speaker after disconnecting the white connecter from m/b could be the reason?

Is there a way to change the driver boards and what is the part i look for? So i changed the ribbon and it stopped cycling and i can hear all sounds and the background voices however, is still a dark blue screen. Before it started cycling i did notice faint lines in the screen and unplugging and plugging worked until it didn't.

Thanks for the video, managed to get my 75" UN75NU800 working again by taping off just pin on the left flex cable connecting to the left two LCD driver boards. Howver now there is a horizontal line running across the entire screen. Is it something that can be fixed by covering more pin or it's probably the best result already? Thanks.

HELP ! Great video, , I have the same tv, I have found the side that is shorting, I can get the back lights to stay on and I get sound, but no picture at all ? I would have thought that with the bad side disconnected I would have half a good picture ? but nothing

Hi could you not scope at the test points or check with a multimeter to find the faulty line/s. Excellent video, subscribed.

Thank you.I have the same tv and did what you recommended but now the color is purplish on the repaired side. Do you have any recommendations. Thank you for your help.

So if you buy I new cable pin conector resolve the problem?

I have had a similar fault issue. Unfortunately the faulty clock line was on the left (when looking from behind the TV) only one cable and a smaller one going to the right hand side. Managed to get the picture to come on but after several seconds the TV goes into continuous starting up loop without any buttons being pressed. Have you come across a similar fault and if so how did you rectify it? Love watching your uploads very informative, many thanks. 👏👍🏴󠁧󠁢󠁷󠁬󠁳󠁿👏👍🏴󠁧󠁢󠁷󠁬󠁳󠁿

I have almost exactly the same television except mine is a 75 inch. Not sure if you know the answer to this (or anybody who knows about this TV) but my symptoms are that when you go to turn it on, the (Samsung) logo comes on solid at first… and then these horizontal lines develop (which chops up and dims the picture a bit)... and then the TV shuts off and goes through that cycle again. Usually for 10 minutes or so, it reboots, over and over again. When it's just about to turn on and work - and I do hear that tone from the speakers, once it gets to this point, - (which it does usually in less than 15 minutes of letting it cycle like this) you start to see the main menu screen, etc. and then the horizontal lines develop and then it shuts off ... and restarts and then FINALLY, it comes on for a few seconds (with the sound of whatever the TV show is that's playing or whatever) then, it usually goes through one more cycle... and then it stays on (and works perfectly from that point on unless you turn the TV off again). I'm wondering if that's a power board issue (rather than a main board issue). According to the seller who sold it to me, It did start occurring, just after a lightning storm. Do you think replacing the whole power board would do the trick in fixing it? Short of that, is there a particular part (or two) on the power board that would usually be the culprit that I could replace for a lot less money than replacing the whole power board? Even if I have to pay about 125 bucks for a new board, I think it would be worth it. It's a great TV once it stays on. Thanks!

Hi, I followed your technique, tv would restart and boot then restart , looping. I taped over 3 clock signals on the left hand side ribbon. Now the tv boots up, I can hear the chime and tv turns off and on with remote , backlight on , etc. But no picture , just I hear sound via the hdmi input . Backlight is on and tv does not boot loop anymore. Do you think my main board tcon side of it faulty or is my screen itself faulty and no matter what I tape up on the ribbon signals , still no picture but audio only! Hope you can help ?

Hi! Will this fix work on qe50q60aau?

My 2019 55" 4k Qled Q80r keeps rebooting every 5 to 6 seconds. The picture comes on and then fades away before restarting all over again. I posted a video of it in my videos. What could be causing this? Sonetimes this issue goes away but always comes back. The backlights are fine and if i unplug cables from main board, the backlights stay on. Thoughts?

Hi please help, i have same situation, but no sound when i turn on the tv, i found the short contact and i isolated but still screen is black with a backlight on, and nothing else, after isolating that contact is not restarting anymore but as i said its stays black screen with backlight on, the red light from tv its showing that responding to remote because when pressing some button from remote the red light from tv is blinking, and also i can turn tv off or on from remote! What could be the problem? Maybe motherboard? If yes what to do? (I have programmer) myabe to install the firmware to the chip! Thanks a lot! Tv samsung ue50tu8000k

where can I buy that kind of tape ? can I just use scotch tape or eletrical tape ?

Ok, I don't know why Samsung "Crystal" tv's line is so bad, but there's nothing else I can do than to try this method, thanks, i hope I can just fix it like you did, it's my mom's tv and it's less than 2 years old lol, and my 12 years old Sony TV is still going strong, so sad btw...

Sir ho we can change t-con board when it comes (alone) between the pannel and main board? that we need to consider?

After you fixed the other two, was the same spot being taped?

Nice video, tried what you did and it worked but that distortion is the issue at the end of the dsy. i actually figured out what the solution is without the tape and blocking of the lines and still get the fullm clear picture.

I have the same problem. TV Restart again and again, also I have these issues -- The TV is connected with Setup box via HDMI, so when I turn on the TV it shows the video and audio from the dish setup box. Also the samsung smart consoles what i mean is the menus that samsung have is not working. Means like when the tv is on when i click settings button some other buttons like volume the samsung UI doesn't shows any consoles. Will it be a same problem ? Would be great if you help me. Can you please guide me ?

My Samsung ua65nu7100 backlight comes on and off by itself in a loop. I have 2 Tcon ribbons. I removed one ribbon at a time. Backlight stays on but no image on the tv. I do hear the boot up chime. Suspect main board issue

I have horizontal lines. How to block here?

I was able to find the short but when I turn it on the screen is still blank. The backlight I can see is on, I can here it do something when I press around on the remote. Is the panel just broken? Can I do more to get a picture?

So how do you know which lines are the clock signal lines on the ribbon itself ??

I have a 2013 40" Samsung Tv it comes on an works perfectly for about 20 minutes then the screen blanks off. for a while mt game is still running in the background as you can hear the game play. Then the Red light starts to blink it will only turn off by unplugging it then it works fine again for 10 minutes or so. Could it be the LED lights? I didnt think power cause it's still running. I do get the Samsung Sound when it starts. Love your vids. Thanks

Show me what pins you taped? 

So i've got 1 single pin blocked off now that makes the tv staying on, but there is still no picture. Do I have to block more off? I can see a little bit of the apps at the edge in the bottom corners, but when i "move" around through the apps they doesn't move. It's almost like it's burned in. You've come across that before?

If you see qled tv samsung on the sreen is the panel defect??

I tried to fix the tv and put the tape in the ribbon and its working it stopped the on and off but the screen appears only white..can you give me some advice??thank you by the way i have the idea now where exactly the problem of my tv

So my tv was constantly power cycling, narrowed down the pin and put the strip of tape on. Now it powers on and can hear sound, but no image just the backlight. Any ideas?

Followed your diagnosis on this tv. On mine the display seems to work fine if I leave the power cord unplugged and unplug the large white ribbon cable from the motherboard to the display, then plug the power cable in and while the backlight is on, plug the ribbon cable in and then everything works fine until I turn the tv off. Then have to repeat that all over again anytime I want to watch tv. Any ideas what could be the issue? Hope that makes sense

I finally found the correct clock signal pin to cover with my tape. The tv turns on now and does not power cycle anymore but I still have no image. Just a blue screen. I hear the menus and the different command s from the remote but no image. At this point im thinking it's game over ?

Every tu and nu Series at at fault cut clock pin 2 and 4 with a razor

I followed your steps however there's no charming sound that means the board is defective?

Hey, i tried this method myself and it worked! I blocked the pin that was broken but now the other problem that i have is that there are relative loads of black lines in the screen, anyone knows how to fix this?

Maybe someone here can help me I don't have the exact problem with it being stuck in a bootloop. My problem is it starts up fine works for about 5min then freezes turns off and then is stuck in a bootloop for a couple min then works fine again so it's basically a bootloop but the looping stops for about 5 min every couple min. I've replaced the powerboard which was my first idea which didn't help so I'm also thinking it's a problem with a shorted led but the long bootloop makes it harder to diagnose. If you have any idea what else it could be please let me know 🙏 :)

I think those black things you talk about are 0 ohm resistors 1 of each clk signal you can just desolder the one malfuctioning and no need to use the capcon tape

this is my last Samsung tv

I have a 4 tv all tv is samsung qe50q60tau has a same problem but I taped the lines the backlight is stable but no picture on the tv the VSS measuring point not arriving the -4,11V whats the problem?

My TV samscum works for about 45 mins an hour then starts power cycling...

I think this is the problem but I'm still suck on how to fix it

can u just buy and replace with a new cable ribbon

This is a temporary solution, after about 2 months the problem will reappear.
