Hello everyone (I'm new here)!
Anyway... I am having issues with the motherboard on my Pacman machine. When the game is powered on, the game goes through it's startup test, shows the white grid, then the game starts. The only problem is that there are small flickering blue vertical lines covering the screen. When the game is in service mode, those lines change to white. When the image is frozen (dip switch 8 is on) the lines go away, but sometimes two or three flickering lines show up on the top of the screen. This problem also seems to affect the sprites. Two of the ghosts are just a few flickering lines. Finally, sometimes one small part of the screen might start to curve (happens shortly then goes away).
Otherwise, the game runs fine and the sound is fine.
