how do you know you lost HV? did you check with a probe?

exactly what happened, would be good to know the sequence of events.

Probed it... Nothing and dont hear the high pitched whine. So I noticed my horizontal wasnt right so I tried adjusting the hold. No luck. So then I tried adjusting the horizontal centering, Fixed it until I took my screwdriver out. When I was pulling it out the screw for the adjustments broke off and I got a large purple/blue spark. The HV immediately died. Tried turning it on again nothing. Pulled the chassis back out of the cabinet. Saw the two blown fuses thought it was that apparently not. Then I saw that the power supply fuse was blown and I think that maybe could have caused the problem. Opened up the cage and didnt see any visual damage except for the broken plastic screw that I was trying to adjust.

the horz adj pot has a plastic knob so that should have done nothing.
were you using metal screwdriver? touch the pot and chassis with the metal shaft?
