Hi;
I have a SD that when fired up, does nothing but light the select and start LEDs on the CP (they remain constantly lit).
The spot killer remains lit and then quickly blinks every 2 seconds(approx).
When I place the game in test, the "inputs" all make sounds as they are supposed to but there is no display, spot killer is on (steady).
All voltages are good from the cab and I have +5vdc. +15vdc and -15vdc on the PCB, (LED is lit).
I replaced the CPU with a known-good and still NADA.
Any pointers would be appreciated.
Thanks in advance
Jeff
