Laemeur Posted October 2, 2011 Share Posted October 2, 2011 Hello, folks. I was out of the country for a few months, came back and switched-on my Atari and during its period of neglect it seems to have developed a rolling black-bar video problem. I've put a video up on YouTube . And here's a still: After I switch it on, as you can see in the video, it sometimes almost looks okay for a few seconds, but then the colour changes and the bar gets really intense. The computer is an NTSC 800XL. The problem is definitely on the computer, as the monitor behaves perfectly with other sources. Anybody familiar with this and know what components I need to look at to get it righted? Thanks for taking the time to look. Quote Link to comment Share on other sites More sharing options...
+bob1200xl Posted October 2, 2011 Share Posted October 2, 2011 Careful... looks like bad filter capacitors in your power supply. Try a different power supply. Isn't the audio trashed, also?

Laemeur Posted October 2, 2011 Author Share Posted October 2, 2011 The audio's still good for now, actually. I suspected the power supply would come up, but I don't have a spare to test with. Quote Link to comment Share on other sites More sharing options...
Bryan Posted October 2, 2011 Share Posted October 2, 2011 What do you want to bet that's an ingot supply? Do you have a voltmeter? Make sure it's not putting out more than 5V as well. Quote Link to comment Share on other sites More sharing options...
Laemeur Posted October 3, 2011 Author Share Posted October 3, 2011 It is an ingot power supply, as a matter of fact. Yep, you guys were right -- I just put the Atari on a different power supply and it looks great. Thanks for your help! Quote Link to comment Share on other sites More sharing options...
