I'm blowing a fuse on the power supply board in the operator console of my D4. It's the 3.15A fuse closest to the rear edge of the board. It blows immediately as soon as power is connected. It's the fuse inside the holder in the center of the second photo. Because of this the monitor stays dark and the console does not communicate with the PC in the cabinet. I've tried a borrowed good power supply, disconnecting the monitor, and disconnecting the other ribbon cables.
Has anyone here experienced this? Anyone know exactly what that fuse supplies power to?
When the shop is perfectly quiet I can hear a whistle/squeal/hiss noise from the monitor area when power is on, is that normal?
I'm out of things to try, any help would be gratefully appreciated!
