I have a friend with a Gottlieb Vegas which has a gottlieb system 3 MPU that is having issues. Game turns on but gives him error code 0631 and does not allow him to start a game. Anyone have any idea what could be going on? He doesn't have the manual and is trying to avoid spending the $25 to order one if possible. Any assistance is greatly appreciated.

No battery acid on the board, something else must be causing the issue out of the blue.

Is he getting any beeps on initial startup?

I think that is the code that comes up when the battery is bad. If so, he can hit the reset button on the MPU board and the game will start, but it won't hold any settings, high scores, etc after losing power.

I bought a 2 AA battery holder from Radio Shack and soldered it in place of the old coin style battery, worked fine. Some systems may not like this, but for $2 I took the chance.

is WW a system 3 or system11? I have the manual and guide in the cabinet I can look at when I get home for troubleshooting.

On system 3 the DMD will usually display "bad battery" but not always so check that by above stated. Also, check the 5v output at top of picture. There is a little "pot" blue I think, on the power supply (board in the middle) that is notorious for causing problems. Good luck.

Thanks for all the advice, I will give him a hand and hope it is one of the two
