I've seen several (older) RCA's do this on startup. The tube is producing
enough emission to slightly light the tube before the vertical circuit has
started, then the vertical starts, giving the all over screen w/ retrace,
because the video circuits aren't on yet. Try turning the screen control down a
little and see if this still happens.
