A new to me Capcom Breakshot is stuck in attract mode. Opening the coin door will NOT put the pin into diagnostic / test mode.
It fully boots, all playfield lights work, the DMD works, and displays attract screens. None of the buttons do anything and opening the coin door does not put it into attract mode.
It says 0 credits, but the game has not coin mech, so I can't easily try to add credits.
Possible issues (sorry for any red herrings in this list, I am not sure what is relevant):
-Opening the coin door does NOT put the game into diagnostic mode. I have pulled the CPU J9 connector off of the CPU (the connection for the coin door open switch goes) and I have shorted the J9-10 pin to the J9-9 pin, which when I read the manual this is circuit it shows for the coin door being open, but nothing happens.
-Additionally, and oddly, when I pull the CPU J9 connector off, and test the voltage on the J9-9 pin is 4.72 volts, HOWEVER, when I jumper the J9-9 pin to the J9-10 pin the voltage drops to 0.00 on both pins. It is like the power to the J9-9 pin is being shut off when a connection is made the J9-10 pin.
-I have tested the connection of the CPU J9 pins and they do have continuity from the pin to the traces on the board (I had hoped it was something simple like the connector was pulled hard and the solder joints were cracked, that does not appear to be the case).
-The pin will not load the balls from the outhole/drain into the ball trough, all three balls just sit piled up in the outhole area.
-The previous owner installed LEDs through the playfield, so all bets are off on what he could have shorted, disconnected or hooked up wrong while putting in the LEDs (unrelated these LEDs look like shit, they are a flickering mess when it looks like the pin is trying to do a nice fade in/out, instead I get to see a flickering light show.)
Any suggestions would be greatly appreciated.
