I'm stealing the "picket fence" term from Gorfchampion, since it does a pretty good job of describing this issue. As the mines move across the screen, they leave a "picket fence" of lines (as can be barely seen in my crappy phone photo). The lines stay there and you can shoot them with torpedoes and it acts as if you blew up a mine. You can shoot a hole through the "fence" and hit the ships above, but as a new mine comes by it leaves a new trail of lines.
I'm almost certain the issue is not on the mother board. I've tried two sets of ROMS, and the RAM all seems to test good. The edge connectors have been replaced, so that should not be an issue. The power supply has been rebuilt and puts out the proper voltages. The game coins up, plays, keep score otherwise as normal.
Any idea where to start tracking this down?
And, no laughing at the insane amount of burn on this tube
