Do you have the schematic and a multimeter?

You need to verify that you're getting the correct voltages out of the
power supply.

Sounds like the game isn't getting power, or is getting the wrong
power. You need to verify that you're getting the correct voltages out
of the power supply.

I'd be looking for bad IC sockets on a game this old. Not uncommon at
all. If you can easily pull out IC's with just your finger tips then
that socket is probably toast.

I fix those boards, but I'm not inexpensive!
