I am working on a Mortal Kombat 2 board that has some vertical lines running up and down on the screen. This is the worst it has looked. It is generally playable but the back ground images have a few lines in them.
So far I have tested and verified all ROMS, (corrected 3 bad ROMS on the main PCB) and replaced the UA11 RAM that was showing bad in test. Now all tests are good, but the problem is still there.
Anyone had this problem or ideas on a solution?
Included a picture of monitor during test to show the monitor is fine and the bad ua11 which has been replaced.
