Re: Toshiba 37E200U No Power (Dead)
That is way too low, I expected >15VDC.

Re: Toshiba 37E200U No Power (Dead)
double checked and it is definitely 6.74vdc on the emitter relative to primary groundYou Can't Succeed Until You're Willing to FailComment

Re: Toshiba 37E200U No Power (Dead)
Well, I cannot trace much further on how Q503 Emitter is connected in the circuit, there are so many small traces running under the SMD parts. I am trying to draw out the diagram but it is not easy so far unless I have the board right in front of me.Never stop learning

Re: Toshiba 37E200U No Power (Dead)
it looks like the emitter runs to Q504. Is it possible that C509 and C504 are bad causing the low reading?You Can't Succeed Until You're Willing to FailComment

Re: Toshiba 37E200U No Power (Dead)
Sorry, I can only trace so much connections from the pictures. I need to have the board in front of me at this point.Never stop learning

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.... -
