Just moved my WOZ to a new location and ran into a problem. No display and no playfield lights! Checked the CPU connectors and connector behind the display (swiveled the display down for access), but all connections look good. The CPU fan is running and I get green LEDs all around on the PCBs in the bottom of the cabinet, though the CPU LED indicator light on a PCB flashes rather than stays solid. Most importantly, after booting the machine, in order to get anything on the backbox display, each time I have to physically press the on/off button on the display, with the LED light first going green and a "No Signal" message on the display, then that LED goes red and flashes.
Any ideas? I'm stumped.
