Trying to get my Robotron PBC working, here's the skinny:
The PCB was installed in a Jamma cab with a switcher/new PS and was working fine for a long time.
Hooked it up recently (in same configuration) and I get nothing, blank screen and no numbers on the LED readout.
Added a 4164 RAM kit and adapter AFTER the blank screen problem, hoping that was the problem, but still the same.
Where should I start in diagnosing the problem?
