often bad solder joints on the CRT socket PCB or wiring from it to the main
board.

Or a bad CRT socket.

Assuming that the problem is within the monitor, and not as others have
suggested, an external cable problem, then probably 75% of intermittent gun
problems are down to bad joints on the CRT base PCB, where the drive
amplifiers are usually located. Often, the drys are on output transistor
legs.

I didn't suggest that the cable was the problem, but rather that that was
where the OP should begin troubleshooting. Has he?

Ah, but you weren't the only one who suggested the possibility of a cable
problem William, which is why I said "others" ... :-)
