As stated above. Accidentally inserted U45 backwards in socket while replacing it...I know ... I know... :/
Now The CPU boots with only the red 5v light on. Any help in tracing down this repair appreciated.
Game has nvram, no acid damage.
All fuses in the game are the correct value and not blown.
Power supply was rebuilt recently and is producing the correct voltages (+5 and +12v)
Unplug everything but 1J17, and power the game on. Same issue.
Picking up a logic probe today. No spare 6802 or PIAs on hand.
