My HD-CRT Sony intermittently does the same thing with the red gun then goes into shutdown if I don't catch it in time. I've been trying to fix the issue for a few years. It was mostly a summer issue and I thought it was a CRT H-K short (tapping on the neck of the CRT would clear the issue for a while) and I actually floated the CRT heater supply to try and stop it (which worked for a few weeks).
This winter I became convinced it is a neck board IC issue... Humidity in the house drops well below %20 in winter and the issue always almost completely vanished in winter, and it did until mid winter this year when I got a humidifier and at %45 humidity the issue became as bad in winter as in summer. I got a used neck board for my set and when I get time I plan to swap boards and see if that cures the issue.
