Tech: Indiana Jones/Atari System 1 pcb problems

Archived from groups: rec.games.video.arcade (More info?)

i just aquired an Indiana Jones and have a garbled screen(kinda like
colorful Galaga boot up screen but also blinks in different boxes). there
is no game play at all or sounds! test switch on AR pcb has no change at
all! i haven't worked on System 1 boards or Indiana but reseated all chips!

i have +5 verified at test points on both pcbs but System 1 only has lower
LED light on....is the upper LED suppose to light also?

any ideas/fixes are welcome!

TIA
Kelly

    The garbage characters on the screen makes it sound like it is in a
    continuous reset loop. Can you get it to come up in test mode? I'd suspect
    a ram or rom, bad socket, etc.

    more like 1/4 inch pixels(boxes) with different colors(like Galaga boot)
    all over the screen!

    test mode does nothing at all. i have reseated and cleaned legs of chips!

    should the System 1 pcb have two LEDs lit? top one is not on mine!
