So I've had this Asteroids in the shop for a few weeks. Originally it had some problems that I repaired:

The game has been running fine for the past two weeks. Friday, we played a bunch of games on it with no problems.
Monday, I delivered it to a customer and it came up fine. We played a few games on it and everything was ok. As I'm standing there talking to her, the screen goes blank and the start buttons are flashing rapidly. I pull the game back out and open the back door. I reseat the connector, push on some chips, and turn it back on, and the game is working again. I put the back door on and put it back against the wall and the screen goes out and the buttons are blinking again.
I pull it back out and check voltages. Everything is fine. While I'm sitting there thinking, the screen comes back on and everything is fine. After about a minute the screen goes out and the buttons are flashing fast again.
Now, it won't come back up. Spotkiller is on, LEDs flash very fast, and nothing. +5 is perfect. Flipping to test mode gives no beeps. Asteroids Encyclopedia mentions K5 can cause this. Replaced it and it didn't help.
I tried the board in another working game, and I get the same result, so I know it's a board issue. Also, I swapped all the socketed chips from the good board to this board and it didn't help, and the good board still works with these ROMs and 6502.
Anyone got an idea???
