Operation Thunder.
Board LED's are solid on and not blinking. I have 5 volts coming out of the power supply. The alphanumeric does not light up. The resistor board is overheating and is burnt.
Game turns on and does not boot up.
Yes all fuses were checked, along with all connectors. As a goof I replaced the U11 chip. No difference.
With game off, when I unplugged the cable between the driver board and cpu board, and turned game on, the main play field coils powered up
Yes, I looked through two on line system 3 guides. No immediate help there.
Where should I go next?
