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.

Thanks for the reply. No reset button in sight. I read this and the related threads and reseated all the relevant connectors. Now I get the same error message as at the very end of the following thread:

Essentially, the message says that all settings were reset to default values, and to press F1 to run setup and F2 to load default values and run setup.

Any further ideas are appreciated. The thread linked above did not end in any resolution to this error message.

Thanks. I'll try that and get back.

WOZ is now booting. I both jumpered the reset pins as suggested above and then tried the F2 key after hooking up a keyboard via a USB. After hitting F2, first I got a JJP screen, then a request for a password! (ummmm . . .). So I powered the game off; then when I powered the game on the machine booted and all was well. Thanks to Lloyd and others who replied.

Thanks much. Will do.
