Sony XBR-65X850E help: three "new boards" are bad?
I am trying to repair my Sony XBR-65X850E.
The screen doesn't power on so I thought it was a bad PSB, I took it out and measured two shorted diodes. I ordered a new board from TVPartsToday but it had three shorted diodes. I ordered a replacement board but that too had the same three shorted diodes. Then, I ordered another replacement board which had only one shorted diode. Interestingly, all four boards (mine and the three new ones) had the same bad diode (bottom left). I contacted them and they said all three boards being bad is statistically improbable and voltage readings can be misleading, and that it's likely a different issue, such as a main board.
Am I just incredibly unlucky with these boards or is it normal for certain diodes to read as shorted?
