I have an Atari Star Wars with a 19" Amplifone vector that is snapping in and out of focus.
Symptoms: Starting from a sharp focus the monitor will slowly (over about 3 to 4 seconds) get blurrier and blurrier until it instantly snaps back into sharp focus. Repeat.
I have replaced the flyback with one from ArcadePartsandRepair and recapped the HV board. No change. There is an article in Gregg Woodcocks' amplifone guide, that matches the symptoms almost 100%, but I opening the neck connector and checking it doesn't seem to reveal the issue he said to look for.
Any ideas CRT friends?
