Hello I am new to the site and the hobby. I got my first non working Ms. PacMan game a couple of weeks ago. I got it home and drilled out the lock to make sure everything was 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 pictures the score, lives, and the fruit is all garbled or corrupted.
I have already pulled all the roms, socketed chips and CPU. I cleaned them and reseated them. I have also pulled the CPU chip from the daughter board and put it on the main board. I have also removed the ram chips and put them in a different socket to see if the problem would move elsewhere. I still have the same issue. Any ideas on how to fix? Thanks for the help.
