Hi,
I'm having a problem with my Devils Dare not starting. When I turn it on, everything will come on normally for a second or two and then the displays will suddenly go blank and coins switches and start switch won't respond at all. Sometimes the displays will also go to a bright, locked on digit in a few of the positions. If I hit the coin switch during this initial 2 seconds, it coins up fine. If I then try turning it off/on again, it will go immediately to the locked up condition and skip the initial 2 normal seconds. If I then unplug the power to the CPU, the next power on will have the initial normal two seconds. Voltages on the power supply seem ok and at least initial voltage checks on the CPU board seem ok. I've tried it with every combination of connectors unplugged, but the behavior is the same.
Does anyone have any suggestions what could be wrong here?
Thanks
Charlie
