Need some help and I've given up on scanning through the thread. If this has been brought up, please point me in the right direction.
Game ran fine for two years and someone put in a different power supply kit before i got the game. But now when I turn it on the game is stuck and wont finish its boot. I get no sounds, but can hear the speaker hum. I have all the lights flashing on the playfield as if it's like a pinball and you're doing a lamp test. The displays read zero on each one. The test button on cpu does nothing.
I've tested the voltages on TP 8 and 9 of the cpu. I've adjusted the power supply and now have 6 and 12 volts on those test points. Originally had only 10 on test point 9.
Any help would be appreciated.
