I got a mint Odyssey2 for a guy for 10 bucks with 9 boxed games. He also gave me the switch box. It powers up but no game play. I get horizontal lines then a clean black screen. When I press 1 or anything I get a response, like the reset horizontal lines and sometimes a horizontal flipping screen. I turned it to channel 4 and I heard all the blips and bleeps. I will clean the carts good I guess, but I think it's something else. Do you guys have any advise?
