I have a pacman and a ms pacman board both dead, but I have been focusing on the Pacman board. When I got it it was completely dead. I replaced the crystal and the 74ls368 at 8b. That brought the board to life. I got short vertical lines on the monitor. The test switch does nothing.

I followed the sync and video paths and found that the 74ls161s at 2s and 2r had some stuck pins so I replaced those chips. So now I get rows of short vertical lines filling the screenPXL_20250830_181526193.jpg
But if I press p1 start the games plays and has sound and looks like this

I can see thin lines of the sprites for the ghosts and pacman and I can move him around. The test switch seems to work and I can do the sound test.
I swapped the 74ls161s at 3s and 3r hoping that would be the problem. It did nothing. I swapped all the 2114s at 4k-4r and put in a set of all 6 roms I bought. Still running the same. Ive probed around the other ram chips and other parts of the video circuit but I don't see anything obviously bad
I was hoping someone here could point me in the direction to start looking before I just start throwing parts at this thing. Thanks for any help I can get
 
So sometimes I feel a little dumb. I had adjusted that a little bit each way and it made no difference, but I didn't want to turn it very far because I'm not at all familiar with adjusting these monitors. I cranked it over a full turn to the right and the picture came right in. It still needs a little adjustment and a good cleaning
Thank you

They are I was using the character roms out of a spare Ms pacman board I had. I've put the original chips back in.
