IIRC, some models turned the B+ to the crosshatch generator on only when the video source was switched to the convergence pattern, to prevent "bleed through" of the pattern. I'm guessing that there might have been a "tin whisker" somewhere in the crosshatch circuit, or even in the switch that was cleared after the application of voltage. Just a WAG, however!
