Standby light is on and blinks once every 5-10 seconds even without a power on command. I have already verified that the power adapter is outputting 14V as required. I opened it up and have a photo of the PWA inside (single board). I am able to measure voltages and solder, so hoping I can get it fixed up. Anyone out there have a schematic with expected voltage points?
Thanks,
Chris
Is this a good question?

@cdonns so the next thing to check is the power board. Your error suggest that the power supply has failed. Post some images of your boards with your question so we can see what you see.
Was this answer helpful?
Thanks for taking the time turkey, sorry for the board pic, thought I had submitted it. Should be there now, just the one board.
any chance you can zoom in on the connector side?
Interested in looking at the backlight connector etc.
Added some more closeups of a few connectors on the board. Let me know if you want to see something else.
Hi @oldturkey03, any further insight on my possible problem. I actually purchased a new main board off of eBay and the display still did not work. It actually got worse (standby light wouldn't even turn on) so I'm guessing they sold me a junk board, working that on issue now too! Ha
CN301 the power connector? any chance you can measure the voltage on there? For now I am trying to find a schematic for either the Samsung BN94-11254F or the Samsung BN94-08857Z boards.
