I have a Firepower 2 that was getting an error code 9. Door switch was good so I decided to replace IC19. I added a socket and put in a new chip.When pulling off the old IC, I managed to crack its grounding cap. I replace it with a 103 ceramic disk cap I had on hand. However, now I can’t exit Diagnostic Mode.
I’ve tried having the coin door open and power cycling twice. However when I advance through function 50 to get back to game over, the machine seems to reset and go back to Diagnostic Mode. The other strange thing is that if I advance to function 19, and it stays there momentarily, it hangs and won’t move off 19.
Continuity check shows the chip legs are contacting the pads.
I’m not sure what to do next. Any have any ideas?
EDIT: Right after this I decided to put back in the old IC19 and the game went back to its previous state. Still giving a error 9, but I could at least start a game. I’ve attached a picture of the old/new IC19. Is the new the correct part number? They seem very close.
