Benzman66 - I'm not handy so I am going to ask someone to help me out. Can you explain to me the "why"?

Hey Everyone, Glad I found an active Atari forum. Hoping someone can help me out. I just got all nostalgic and went and got an Atari 2600 and 48 games, controllers, etc.. off Ebay (for $50 no less!) and I got it and hooked it up. Well after playing for a few minutes the picture gets distorted and the coloring swirls. It's hard to desrcibe but I guess the best way to describe it might be akin to putting a magnet near the picture, like it needs to be degoussed (sp?). Anyway if I turn off the Atari and then back on, it's fine again. Has anyone experienced this and found a solution? I am using an RCA to Coax connector if that helps. The TV is a Samsung 50" DLP HDTV. My hypothesis centers around some sort of shielding issue only because the game itself is fine. If you can live with the color distorting there is no issue. Any help would be great! Also as an aside I'm looking for the following games: Megamania Kaboom Any Star Wars (Except Empire) Thanks!!
