Quoted from johnwartjr:
Correct, 2532 is the game #, and it's on revision 2 ROMs.
If it won't come off the diagnostic code, it could be bad RAM, and I've seen a failed 7404 cause this as well. But I can't diagnose this particular failure based off the limited information we have at this time. Just noting that those particular causes have happened before. Best to properly diagnose and repair it rather than shotgun.
Ok. So I jumped back into it today and here's what it is doing.
I ran the sound test and it all checked out. The SW2 switch gave me all the speech without anything missing or partial.
When I the game is in attract mode and I hit the SW1 switch to do the memory test, my LED display gives me a 0.
I tried leaving the door open to ensure it would show a 5 and it did.
The game coins up fine, but when I hit the start button the game "half boots" (clunking noises of switches firing, etc) but a ball never kicks out and the playfield has no power.
When I'm cycling through test mode everything on the playfield will fire, and it appears as though it will play fine.
