If I am understandin you correctly, I think if you go to an electronics store such as Radio Shack-you can get a automatic tv/game switch. This plugs into the video input on the t.v. and the other end goes into the atari system. They are pretty cheap ($5) and give a better picture than the old box manual switch.
I hope this helps. You can check my site for a list of games at www.netcolony.com/members/addie.
