Not necessarily...

Yes; the chassis transistors!!! Try swapping those and make CERTAIN the
ones on the "bad" monitor are properly insulated. I suspect the problem is
a poorly insulated transistor allowing the chassis to drift away from ground
and then short into the focus assembly from the frame...
