(oh no not another one!)
Boardset:
namco PPII set, in a namco cab
Possible Dependencies:
Original power supply used only for monitor ISO (original PS PCB missing)
Switch Mode supply used (PChou 5v15A switcher, or 5v24A ATX PSU)
Voltage measured at board connector slightly under 4.7v (yeah i know it is too low so i have to look at an alternate PSU setup to deliver correct voltage at board power connectors)
Issue Scenario:
game boots up ok. and is rock solid.
get track select display, stable for a few seconds, starts rolling vertically.
select track ok (just hard whilst rolling)
game starts, and is rock solid.
The Question:
Other than the obvious power supply issue, has anyone seen this type of symptom and have some suggestions as to what else to look at for a reason for the display rolling ONLY during track selection ?
thanks!
