I am having a strange issue with my Apple 2c. It will boot up fine, but after it warms up which takes about 30 seconds the text starts to get distorted and fuzzy. It keeps getting worse until it can't be read at all. Turning it off and on again does nto effect it unless I let set unplugged for 5+ min then it works fine for another 30 seconds. I can still type and run commands fine, I just can't read/see anything. It is a rev 2(0) board with no mods. I looked at the board and did not see any caps leaking. I did swap the 6 biggest ones to see if that was it, no luck. I also unplugged the floppy, and it makes it take longer before glitching out, maybe 2-3 minutes vs 30 seconds, so that makes me wonder if it is in the power board.
Any ideas?? I have uploaded a video so you can see the distortion. https://youtu.be/3pZoFFXiKlo
