I have an Odyssey 1 and an Odyssey 2. First what kind of 9v power cord should I get. I got a price for almost $19 bucks at Radio shack for one. They never saw something like that before...lol Secondly, my Odyssey 2 isn't showing the picture. The screen is scrambled at the moment, I tried cleaning it but still nothing. What can I do to fix this?
