Black screen, with slow flashing white LED
I have this exact issue, I have replaced all boards, Main video, power board, and T-conn, but i'm now stuck where this question left off. Black screen, with slow flashing white LED. My tv is the XBR65x850C, but having the exact same issue.
Started with not powering on,
replaced power board, nothing,
replaced video board, LED flashed amber/green
Tried to update via USB with latest firmware from sony website,
Now still a black screen with slow flashing white LED.
I'm hoping its not the panel now since I don't have many options left. Any help on this would be great!
Is this a good question?
