My memory served me wrong, or I read the post to fast. Is the symptoms
of a "lost" horizontal hold that the picture will scroll, looping around?
This vt220 in front of me has no picture at all. I was using it and
between the blink of my eyes the picture disappeared, no bang, no smoke,
just gone. I think the logic still works, judging by the led indicators
on the keyboard and the satisfying beep it "boots" just fine.
I believe I did 2 of these last year and they had a fuse on the mother
board ??? both of them where blown and replacing them only blew
another fuse.
Turned out to be a capacitor on both that was shorted. I'm at work
and can't check my notes. Do remember it was a non polarized cap.

Any ideas where I should start looking?
Kind regards,
