Picked up a ms pacman cab today. Pretty clean inside and out, but the pcb is a little dusty. Anyway when i fire it up the screen has a bunch of garbage on screen. Any ideas?

I did and when I looked at the Vram addresser it had some debris on the traces in the back. plugged it back in and the graphics are fine. Tomorrow I'm going to clean the board and test the game for a few hours to make sure that fixed the issue. Thanks for the input guys.
 
Most likely a connection issue between the vram pins and the socket. If the problem comes back you will need to replace the socket on the main board and put a new piggyback socket on the vram card.
