Bootay Posted January 25, 2022 Share Posted January 25, 2022 I was playing a game on my Atari 800XL and this happened. I turned the computer off and back on and it continues to do this. Anyone know how I can fix it? Thanks! 20220125_091342.mp4 Quote Link to comment Share on other sites More sharing options...
TGB1718 Posted January 25, 2022 Share Posted January 25, 2022 Does it sound like it's booting normally (fart noises) or SIO if loading from disk or tape ? Looks like some sort of "sync" issue, have you tried anything else on the monitor to make sure it's not that Quote Link to comment Share on other sites More sharing options...
mimo Posted January 25, 2022 Share Posted January 25, 2022 Which power supply are you using? 1 Quote Link to comment Share on other sites More sharing options...
bfollowell Posted January 25, 2022 Share Posted January 25, 2022 It looks like more of a monitor issue than a computer issue to me. Have you confirmed the computer with another display or the display with another device? Quote Link to comment Share on other sites More sharing options...
Bootay Posted January 25, 2022 Author Share Posted January 25, 2022 It ended up being the power supply. I tried another one and it works fine now. Thanks for the help guys! Turns out, I had the one thats known to be bad. Quote Link to comment Share on other sites More sharing options...

Cut the cable off and toss the rest Quote Link to comment Share on other sites More sharing options...
Paul Westphal Posted January 25, 2022 Share Posted January 25, 2022 (edited) Oh Dude! The dreaded Epoxy anchor. You’re lucky it didn’t go completely out and take out chips on its way. Edited January 25, 2022 by Paul Westphal Quote Link to comment Share on other sites More sharing options...
Nezgar Posted January 25, 2022 Share Posted January 25, 2022 What you see on the screen (bright, then dark scrolling bars - notice the grey/black background if you pause the video) is 60hz AC going into your computer instead of the normal DC. Definitely lobotomize that PSU ASAP. Keep the cord with the DIN end though, you can attach that to a new moder 5V DC power supply. Much easier than soldering wires to pins of a new connector.
