krisjohn Posted October 7, 2003 Share Posted October 7, 2003 I have a XEGS that almost works. It powers up, can load games, sound's fine, but the picture isn't stable. There's a big black bar (horizontal) that rolls around the screen. When it's near the top of the picture it causes the whole picture to roll. Anyone have any idea how to fix this? TIA.

That sounds like 50/60Hz (mains) noise to me. Do you have an alternate power supply you can test? Might you be getting a ground loop? -Bry Quote Link to comment Share on other sites More sharing options...
capnarrr Posted October 8, 2003 Share Posted October 8, 2003 mine did the same exact thing. it was the power supply, not the system. Quote Link to comment Share on other sites More sharing options...

doncleth Posted December 7, 2003 Share Posted December 7, 2003 Hi, I have a similar problem with my power supply ie. the picture rolls. Can the power supply be fixed? Is it worth getting it repaired in an electronic shop or I'll just get a new power supply (from eBay). Any suggestions? TIA, Don Quote Link to comment Share on other sites More sharing options...
krisjohn Posted December 8, 2003 Author Share Posted December 8, 2003 I think you can adapt the power supply of other devices if you're handy with a soldering iron. Someone I gave a XEGS to managed this, but my email archive is at home. I'll try to remember to check what he did. Quote Link to comment Share on other sites More sharing options...
doncleth Posted December 8, 2003 Share Posted December 8, 2003 G'day krisjohn, Thanks for the reply. if you can dig up that email that details how to fix up or create a custom power supply, that'll be great. Cheers, Don Quote Link to comment Share on other sites More sharing options...
krisjohn Posted December 9, 2003 Author Share Posted December 9, 2003 DeV0 made one from a C64 power supply. I've asked him to post how here. Quote Link to comment Share on other sites More sharing options...
DeV0 Posted December 10, 2003 Share Posted December 10, 2003 Hi All This how it works, Just remember that it must be the 7 Pin black commodore PSU, not the beige one. Im sure after ALOT of tampering the beige could work. "You can use one of those black 7 pin c64 PSU's for the XEGS. Just open the black box (PSU) and snip the yellow and the green wires, These are the 9volt AC's which i believe the c64 uses for the SID and printer port??" Oh, you really want to have absolutely no connection at all with the yellow and green wires, In case the wiring is of different colour from your country, just remember that there are 4 wires and the 9V's are the 2 on the right. Has worked for weeks for me, as little heat s if using a c64 Quote Link to comment Share on other sites More sharing options...
