Re: Display panel not working - Sony STR-DN1080
The far left pin has a fracture line. Even if the VFD display soldering looks ok, resolder them anyway.
Then go upstream and check other connections. Like the jumpers, connector pins, even one Kenwood I fixed it was the power transformer pin where the bad connection was for the display filament power loss.
You have to check JR121 might not be soldered on one end.
With no pics of the other end area of the board, hard to nail it.
