Hi all,
I've combed through a lot of posts here and on Google, and I can't seem to come up with a fix for this problem. When I turn the system on with no cart, I get a black screen, no muss no fuss. When I insert a game, I can see small parts of it clearly in the background, but there's a ton of black and white horizontal bars that are vertically scrolling over it. I have tried multiple carts, power supplies, and AV cables to no avail. Nothing seems to be out of place/broken/missing on the board, but my electronics knowledge is limited, so I'm not 100% sure. The A203 chip in the lower-left seems to have some sort of white goop underneath it, I have no idea what that is. I'm running it through one of those old-school AV game switches to RF, but I don't think the box/AV cable is the problem, since everything seems to work fine without a cart. I've tried cleaning the carts with alcohol, and that hasn't helped. A lot of people seem surprised when someone posts that they're having a problem with an Atari, so I figured maybe this is solveable.
Thanks.
