Thank you for sharing your knowledge with us👍

It worked for me! It was a little tedious working with the tape and narrowing it down to just 1 pin but it actually went faster than I expected. There are some slightly darker lines visible up close but it is absolutely usable.

[@GidFix-pl3lg]

I'm glad it worked. The TV is still working perfectly to date. Yes, there are lines but only visible when very close to the TV.

Great info. I had similar issue with a lightly used, four year 75" Samsung QN75Q60TAFXZA. Ordered and replaced the main board $80 and that did not fix the issue so tried this tape method. Covered pins 7 & 8 hoping that would help but the entire left 1/3 of the screen was completing black. Then I covered pins 1-4 and hit the jackpot as 100% of the screen works and looks perfect.

@user-dt3vq5lu1p Comments like yours make me happy. I'm very glad you could get it working again.

Excellent explanation about your troubleshooting. You explain very well the step by step sequence. That is very helpful, keep up the good work.

Thanks for the encouragement.

Great video. I have AU8000 50” I am able to stop boot loop, consistent backlight, sound, and proper standby mode (solid red light when TV off) but I still can’t get any picture unfortunately. I replaced both the power and the main board before I got to this point of pin taping, so I’m positive it’s this. I just haven’t covered the right pins on the ribbon I guess. Close to giving up.

Stop buying Samsung it’s the worst tv out there, can’t believe ppl don’t read reviews.

[@GidFix-pl3lg]

Reading reviews is highly recommended but i believe Samsung still has some good TVs out there.

So please why it happens like that because i was having the same issue on my Qled tv

It's very expensive tv so why they refused to do it quality?

What is the ribbon called? Im thinking of just replacing it.

[@GidFix-pl3lg]

Are you referring to the ribbon that connects the left and right panel driver boards?

[@jujigatame4800]

howd you go

[@voicetube]

I'm curious to see what you think about my issue: I have a Samsung 75 inch LCD (circa 2019) model television. Not sure if you know the answer to this (or anybody watching) 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 are sort of similar to the horizontal lines we see when you first used the tape)... and then the TV shuts off and goes through that cycle again. (And again) for a while… But it does finally turn on within 15 minutes and works fine. Usually for 10 minutes + it reboots, over and over again. When it's just about to turn on and work (which it does usually in less than 15 minutes of letting it cycle like this) it finally gets past the logo and 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 (until you turn the TV off again). I'm wondering if that's a power board issue (rather than a main board issue, or the issue you had)? 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 pwr board, I think it would be worth it. (It's a great TV once it stays on). [After watching your video, I'm guessing it's probably a similar panel problem and rather than open it up and try the tape trick, etc., since it does turn on and stay on after 15 minutes or less, I think I'll just live with it until I can afford to get a new TV. Thank you for posting this video] 🙂

[@GidFix-pl3lg]

Hi, thanks for the detailed explanation about your tv and sorry for the late response. Your issue is quite unique and may be a problem from one or multiple sources. Lightning could have partially affected the power supply or both the power supply and panel itself. Usually, i would try to do some elimination. Since you haven't disassembled, it could be best to use it as it is. However, it may eventually stop working. The first thing i would try is to disconnect the motherboard from the powerboard, and switch it on and test the voltages that feed the motherboard with a multimeter. Ensure the tv has been off for a while so that you can provide the same conditions to replicate the fault. If the voltages fluctuate several times before a constant voltage is achieved, then it may be the powerboard. My reservation is with the horizontal lines that show up every time. That could mean nothing or could be an indication of a panel board or panel issue. You could also listen very closely to the TV if there are any buzzing or unfamiliar sounds when the tv is power cycling. If the powerboard gives constant voltage after disconnecting the motherboard, then try disconnecting the panel ribbon cables from the tcon board or motherboard (depending if this tv has a tcon board or is built into the motherboard), switch it on and test the voltage for fluctuations. If it doesn't fluctuate, then the panel driver board or panel itself could be the issue. If you don't have a multimeter, do the above and see how the backlights behave. I hope this can help you for now. Thanks.

I have 85 inch Samsung tv it has relay clicking problem …can you help me with guidance ?

[@GidFix-pl3lg]

Clicking sound could be a power board issue. Does your TV keep restarting?

[@bhawanjitsingh6283]

@@GidFix-pl3lg yes tv restarting

[@GidFix-pl3lg]

@@bhawanjitsingh6283 Your TV is quite huge. If you are able to open the back, try testing the power board with a multimeter but without a connection to the tv panel from a motherboard. This is one test to eliminate the problem.

[@yky1526]

Since there's a short, is it not possible to do a continuity test to see which lines were shorted?

[@GidFix-pl3lg]

Thanks for the question. Unfortunately, this short seems to be in the panel or screen so it makes it difficult to do such a test.

[@jordannaumceski2269]

Hello, i have Samsung TV, model LE37C530F1W. When the power cord is unplugged and plugged back in, the tv starts itself and is bootlooping about 10 times, then is working normal. Everything is fine until the power cord is unplugged again and it's doing the same thing. I cannot find nothing suspicius, i changed the main big capacitor but it does the same thing. What could be the problem ? Thanks

[@GidFix-pl3lg]

Try disconnecting the motherboard cable from the power supply board. Then, plug it in and use a multimeter to check the output voltage to the motherboard on power supply to see if there are voltage fluctuations. If the voltage is stable, then it's likely your motherboard causing that.

My name is legacy I had come across the problem with 55inchs n I work it

Thanks for the comment. Glad it worked for you.

[@dsstudios5425]

I did this and the screen is now white and pics are negative pliz help

[@GidFix-pl3lg]

I am not really sure what you mean by "pic are negative". Make sure you haven't swapped the ribbon cables. Also, a white screen means you are probably covering more pins than expected. Try to narrow it down and cover as little pins as possible. It requires a lot of trial and patience.

[@decaalv]

I tried the tape trick and could not make it to work. The best I could do was to stop the boot loop.

[@GidFix-pl3lg]

After stopping the bootloop, what do you get on the screen now? Please note that you may have to adjust the tape several times on different pins until you get a good picture. You will need lots of time and patience to eliminate the right one.

[@snowyowlnugget]

​@@GidFix-pl3lg Hello, I've found mine to be a similar model, presumably with the same 'panel issue", and GUESS WHAT, THE PANEL itself is FINE, but something, like you said, must have shorted in the chips on the film, and mine seems to be coming from the right side driver board, but when I tape over the specific pin that I found, (Which seems to be a ground for all i know), it will stop bootlooping, but it now displays no image or sound. when I remove the tape, it can be started but only via the hot-wire method of plugging the cable in after pressing the power button. Any Ideas? (Specific model is the UN70NU6900FXZA), and it's the second pin if you're counting from the left. i.imgur.com/3qWhGPS.jpg

[@Rafal0r]

After covering several pins with tape = no image, backlight is on. After covering the first pin with tape = no image, backlight is on. When nothing is taped, the TV does not turn on/the red LED flashes and the TV backlight blinks Samsung Crystal UHD 50” TU8002

[@GidFix-pl3lg]

I am assuming you are taping the connector at the right side of the panel board. Do you get any sound in any of your scenarios? Disconnect the ribbon cable to the motherboard and check if the backlight will still blink when turned on. If you have a multimeter, you could check if your panel board has voltage coming to them.

[@zwoelebertha]

What kind of tape did you use?

[@GidFix-pl3lg]

Hi, just a regular scotch tape.

[@GidFix-pl3lg]

The spot i taped in the video may be different for your TV. You may have to try taping different spots to get it working. You will need lots of patience to figure the right pins to tape.

[@DominieDirtch]

[@GidFix-pl3lg]

It can be frustrating, but one thing to note is that sometimes the taping would just stop the reboot, but no picture appears, just backlight and sound. In that case, you may need to do as illustrated in this video: m.kzbin.info/www/bejne/fKvbZWqjo5imobs&pp=ygUGZ2lkZml4 I would recommend checking out the video by powerled electronics. The process is delicate. Usually, a short in the panel is just like a cracked screen, almost useless. If you use the process, don't forget to remove the tape. Thanks for the comment.
