Re: Sony OLED XBR65A8G no video, PSU problem?
So what was the outcome of this TV?
I have the same TV as the OP and didn't know if I should start a new thread or not.
Pretty much the same issue, except instead of a red line down the screen, I get a blank screen. 4 red blinks when powered on. Sometimes I could get it to power on after a hard reset, but just blank screen with sound.
I ran the power board stand alone and got these voltages:
EVDD = 22.05V
TCON_12V = 12.69
REG_12V = 12.75
When I plugged in the TCON and tried to power up without main board attached, I didn't get any picture on the screen. I also tried replacing the TCON board but I still did not get any picture on the screen when doing this test.
Does this mean I have a bad panel? Is EVDD correct at 22.06V or should it be closer to 24V?
