Atariman Posted December 30, 2005 Share Posted December 30, 2005 I recently picked up Super Pong at my local game store. The video was very fuzzy and (according to the guy behind the counter) changed a little when he wiggled the cord. Figuring that it was just the video cable, I took it home and opened it up. After replacing the cable (and not fixing the problem) I happened to press on both of the paddle potentiometers. This helped clear up the video issue, but only somewhat. Figuring that perhaps the paddles had some soldering issues (as the solder job was pretty poor to begin with) I resoldered them to find that this didn't solve the problem. It seems that the video is even worse than before and degrades as it warms up... any ideas? Quote Link to comment Share on other sites More sharing options...

There's often a tuning coil which may help things somewhat. If your TV has a fine-tuning adjustment, you could try that; otherwise, find a non-metallic screwdriver and adjust the tuning coil (if all you have is a metalic one, putting the screwdriver near the coil will alter its behavior, so you'll have to adjust it, remove the screwdriver, see what it does, and repeat).

Also, I noticed that the picture improved when I pressed on the I.C. that is inside the pong unit - I would also note that this IC is also getting very hot...

sebastius Posted December 30, 2005 Share Posted December 30, 2005 I think you need to resolder some connections, sounds to me like a broken connection somewhere. Quote Link to comment Share on other sites More sharing options...
