I have a couple missile command boards each with a different video display issue. The first board has leftover garbage on the bottom right hand side of the screen. After the cursor or other new video information has come over the garbage it disappears but reappears after screen refreshes. Game plays fine though. My second board has a double image problem. Imagine two sets of the same image of the screen offset by 1" vertically. This game plays fine also. For sure not a monitor issue or power supply issue. I have to assume it is a chip issue or a cap issue on each board but need someone to point me to the right chips to check or try replacing. thanks.
