My power supply has all the standby voltages and pw_on but no 12V. I disconnected all other boards and jumped the psu still no 12V. Anyone know what could be bad on here? Caps checked good except I didn't test the tiny ones. Maybe regulators bad?? I put my dmm on diode mode and checked them I got a reading in both directions and no reading in both directions. I'm guessing I have to pull them out of circuit to test. The person I bought it off said the repair shop said it had a bad fuse. The only fuses I see are the main which is obviously good and another one by the pin connector which tested good for continuity.

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... -
Hi, I just want to share the repair of my Samsung HPT5054X-XAC plasma TV with no picture. It will end up repairing the BN96-04881A (LJ92-01452A) main logic control board. I hope it will help someone out there.
The TV sound was working perfectly, but no picture at all. I've checked the various voltages on the power supply and found no VS voltage. After some investigation I found that VS_ON was not present.
I traced down the source of the VS_ON signal to the main logic control board.
Voltage at C2014 was good at 5.3 volt and coming from the power supply...05-06-2021, 11:08 PM -
