Somehow, after installing new, updated sound roms, I installed S2 backwards. Yes, I'm an idiot. I orientated the chip and dropped it and picked it back up reversed. On startup, no sound and I unplugged the machine after about 10 seconds. The S2 was very hot, I assume I fried it. I replaced the updated sound chips I likely just fried with the prior working originals. Now I have no sound and a sound board interface issue error and no led light lit on the AV board. Fuses are good. Suggestions as what to repair? Any chance that S2 is still good? Would it fry all of the sound chips? The game has no other errors or play issues but plays soundless. I found no open fuses on any boards.
I reseated the cables, double checked to ensure the OEM sound roms had all their legs in and were in the proper slot and order.
I know I'm being punished by the pinball gods for updating sound chips that I likely couldn't tell the difference with the new ones anyway. But i couldn't help myself. Now I need help. The AV board shows no signs of burns or charring. Anyone else made this mistake?
