JaguarRage Posted November 23, 2017 Share Posted November 23, 2017 I was given a PAL 7800 recently. The unit came as-is, untested with neither the power supply or controller, but 2 games including DKJr (One of my favorites), so I was pretty chuffed. I searched online for some info on a quick fix, and ended up hardwiring a SEGA MegaDrive 2 PSU. The console powers on and plays games! However, after a minute or two of play, the screen will crackle and the picture will disappear, only to glith back to normal seconds later. It repeats this process every few minutes. This issue has reoccurred every time I've tested the system. Any pointers folks? Quote Link to comment Share on other sites More sharing options...
+Mitch Posted November 23, 2017 Share Posted November 23, 2017 So it is a PAL-I 7800? Are you using a crt or LCD tv? Old school rf connection? Or some kind of adapter? Mitch Quote Link to comment Share on other sites More sharing options...
+SmittyB Posted November 23, 2017 Share Posted November 23, 2017 It sounds to me like it's just warming up and the frequency is drifting slightly. I have the same with my 7800 and I just ended up tuning it differently on my TV. Quote Link to comment Share on other sites More sharing options...
JaguarRage Posted November 23, 2017 Author Share Posted November 23, 2017 I'm not sure if it's pal-1, I'l check tomorrow. It's tuned to a fairly new flatscreen as I'm in the process of replacing my CRT monitor. Could it be an issue with the RF on the consoles behalf? Either way, I'm planning to mod it so I can hook it up with composite. Quote Link to comment Share on other sites More sharing options...
JaguarRage Posted November 23, 2017 Author Share Posted November 23, 2017 Yup, PAL 1 Quote Link to comment Share on other sites More sharing options...
+Mitch Posted November 23, 2017 Share Posted November 23, 2017 I suspect it maybe your tv. If you have a crt tv to test with that would be the easiest way to go. Mitch Quote Link to comment Share on other sites More sharing options...
