I need a little help. My motordome will power on and play for about 2 games, sometimes half a game, and sometimes 3 games but it always craps out. So here is what the game does after it craps out. I still have general illumination and that is it. No displays, no solenoids, no flippers, no coin up, and no anything. After cycling the power, it works for another game, or half, or 3. Any ideas?? I have already re-flowed all the pin solder joints on the 6803 MPU. It is the Bally Midway version.

Reflow the power supply too. That usually has worse cold solder issues than the mpu.

I suspect the sockets on the motherboard, do the twist test to see if you get the game to lockup when its working... are you getting power to the displays when it craps, ie orange glow?
