Ok. I thought I had this problem solved but its back. Everything is fine for a while, the games play fine for a few weeks and then I put in a game that I havent played for a while (2600 Alien) and bang - unstable video with rolling images and perfect audio with every cart (2600 or 7800). This has happened a few times now. Eventually the 7800 will just start to work again with no adjustments or anything. Totally baffling. I am wondering if I need to clean the contacts inside the console. I have opened the unit up before just out of curiosity, but I must say, I dont really know what to do or even worse, where to start with fixing my machine. I need some serious help. This is really starting to tick me off. Does anybody know if my machine is faulty or what??
