Sorry for the delay I was out of the town.
I disconnected the screen ribbon cables (no the LVDS) first one and then the other and finally both with the same result: STBY pin fluctuating between 3v and 7vComment

Try some simple tests if you have not yet, with tv unplugged, check all the diodes and resistors on top of the powerboard.Comment

That was the first thing I did, this board has become a puzzle for me.Comment

Report results of Diahs test, important to do tests in order, I think Diah starts with the simple things first, that's the best approach imo.Comment

Hi everyone,
Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.
Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.
I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue.... -

Ever since that night the TV started having a mind of its own, It would randomly turn itself off or on, and all inputs stopped responding like HDMI, aerial, but USB still worked. Anyway, over the next few months... -
