My 8 month old samsung from costco doing this. Junk...no more samsung refrigerator...washer dryer.. cell phone S23 is junk now TV. LG no better. All crap. Buy the warranty from costco i guess

Excuse me, about the blocking method of the right y-axis failure, stv ckv1-8 vss vgl vgh lc1 lc2, about 14 points, corresponding to the right metal dots, should they be shielded? Can’t you just cover a few? I have tried full occlusion and it can be turned on normally, but the color on the right seems to be a little colorless. I just want to know if there is a perfect way to fix it. Find the problematic part inside. Some people also have the application of sharing the short-circuit killer, but I don‘t know if it is suitable.

can't watch anymore camera all over the place,learn to take a video.

Thanks for the help! The power cycling has stopped and the TV works just like before with one small issue. The left side of the screen does not have red colors anymore it seems. Is this due to the tape blocking the signal or might it be something else?

It really works, Thanks a lot😍

Those small lines you have at the bottom after typing... what do you think if that small lines on the whole tv screen instead of just the bottom like yours?

I don't see how you practically solve the problem, how did you do it to stop restarting?

Good morning if I buy a new driver ribbon would I still have the problem

Fk, here goes my whole day tomorrow, I’m having the same issue and narrowed it down to it’s gotta be one of these 😒

✌️✌️✌️✌️

Thanx. I fixed my tv by removing clock signals as per instructions. CE58Q60TAU. I put a paper, covering pin 8-15. Image is slightly degraded but hardly noticable. I agree, samsung tv is a piece of junk. Bad quality and sneaky apps.

Hi, Thanks for the Video, ik clears up a lot. (About the working of the different components) Maybe you can help me diagnose a somewhat similar problem whit my 58 inch Samsung tv. (Exactly the same power supply and Controller board even the display boards are separated the same way) When I turn it on the backlight comes on for a second than dims and the "chime" sound is played. And then it starts al over again. But the chime sound is not played anymore. If I understand you correctly the power supply and the controller board are ok if the chime sound is playing. But because of the backlight is not fully coming on, i guessed the leds don't "take" enough power from the supply and that is shutting down the entire power supply in reboot mode... Am I remotely correct or do you see other ways? English is not my mother tongue, Dutch is, so please forgive me for the grammatical mistakes. Kind regards, David

Thanks, It is very comprehensive video for debugging smart TV display problems. In my Samsung series 8 model the T-con board is integrated in the main board. I also see 2 cables going from power supply to main board. I tested backlight by disconnecting cables from power supply to main board and it is fine. I tried connecting one cable at a time and notice that when one of the cables is connected, the highlights intermittently turns on and off. The behavior is same with connected or disconnected flat ribbon cables. I have replaced the main board but there is no change. Any suggestions?

Would you recommend trying to fix the connections via oven heat or just replscong the whole board?

Great video! Thanks for the help!

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!

I used a blow dryer to get the screen off. It was easy. My problem is getting the bottom plastics off 😢

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?

Greetings Does anyone know how to save individual images and then process them with this camera

3:39 So, you can replace a capacitor with one rated for a higher voltage as long as the microfarad matches?

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

I have a 75. Please send me your shipping address.

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

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

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?

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!

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

Show me what pins you taped? 

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.

What is the better brand that keeps longer playing ps4 too?LG or Samsung?

CapXon makes crap capacitors.

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 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 ?

I saw your Mr. ElectroniCET channel, your channel content is very good. But video views are not good. Your channel has some issues due to which your videos are not getting good views. The main problem is SEO.

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

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

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?

I have horizontal lines. How to block here?

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.

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

If you still have it, is there any chance that you'd be willing to sell the digital board from that RX-A730? I just bought one and the guy who had owned it actually burned the PCB while trying to "cook" that bad IC.

I have a Sanyo I paid about 200 for new. The blackl lights went out after 3 years. I paid a guy $85 to fix it. 4 years later it still works fine. 7 years old now.

Hi. Never startup a switch mode power supply “SMPS” without no load. Thats why you supply voltahe is dropping and rising. Sometimes it Will rise the voltahe so High that it Will damage it self if you test it with no load on main rail.

Oh, it’s gets worse the further you go. If you get the panel out, you’ll find the diffuser box is double-sided adhesive attached, making it very difficult to get to the led strips. Once past that, you’ll find the led strips and the lenses are all glued in. These things are made to become e-waste.

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.

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?

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?

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.
