While repairing my ghosuncher/uni wars (which is an Australian version of Pac-Man/galaga) cocktail table I accidentally hooked up the Jamma harness backwards.
Now it turns on , the sound works but the graphics have turned into coloured ‘blocks’.
The power went through an 1n4002 diode which shorted out and I have replaced but the into a MB3712 ic, wondering if this may be the issue or if I have ‘fried’ something more sinister.
There was no burning smell and I have ordered a new IC.
Any help would be greatly appreciated.
