No caps were testing bad, so I have no way of knowing which cap to remove.

Right there by the tvs diodes, says R6 I believe, right by the DT5 printed there, no joy on the caps or resistor then just remove tvs diode and test tv, I would start with number one, remove test tv no change put it back and try the others same way, no harm will be done as long as done correctly and you don't damage anything during removal. (not much to lose at this point I suppose) See if any of the three gets hotter than the others, if one does then I would start with that one. Might be an easier way to do it but I don't know of any.Comment

Suppose it's a problem with the panel itself. Maybe one of those caps on that board is bad but just not shorted??Comment

yes as you say look at the hot ones use alcohol or a candle to detect look at this https://www.youtube.com/watch?v=srccct1mDIU&t=856sLast edited by bohaboha; 02-06-2025, 12:35 PM.Comment

Hi, I have a Samsung UE50TU with:

This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode... -
Good morning.
the original board of this equipment is in reboots without giving an image or turning on the backlight, the board code is BN94-12926P (BN41-02636), I made a copy of the flash ic1603 and ic1604, dumps attached. I tried to put other dumps (from other popis models I didn't find this board) but without success. That said, I bought a board on ebay BN94-12926A, which in principle should at least give image, even if with defects, this board turns on and responds to the command but does not give any indication of image despite the availability of VHG and VGL voltages as well... -
I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and...
