I got my first non working Ms. PacMan game last week.  I got it home and drilled out the lock to make sure everything is there and found a reset switch on the board.  I pushed it and the game started working.  The game plays but it has some issues.  As you can see  from the picture the score, lives, and the fruit is all garbled or corrupted.  Does anyone know how to fix this? 

I have already pulled the roms and CPU chips and reseated them.  I have also pulled the CPU chip from the daughter board and put it on the main board.  I still have the same issue.

This 'could' be a bad ribbon cable from the main pcb to the daughter board.

I actually fixed it by replacing the VRam Addresser daughter board with the one from Arcade Shop.

A guy on Klov thought it was that board. So I changed it.
