Having to work around the HV and live chassis question

[DavGoodlin]

Hi Jon, Thanks for putting safety first
-Take a long, flat-blade screwdriver and attach an alligator clip jumper cable between the shaft, near the handle and ground it to the HV cage or spring/metal part on the CRT mounting. Then slide the flat blade between the CRT and HV (fat wire, often red) where it attaches to the CRT's ultor button, it may be open or under a rubber cap. You will hear a snap if there was stored potential.

If the set powers up but does not operate, the power supply filter capacitors could hold a charge also. Ground a clip lead to the capacitor can and touch to any large power resistors off the cap and that should do it.

I have been zapped by 25,000 volts (color GE-KD) once by pulling the HV regulator 6BK4 tube cap, after switching the set off. I was just not being careful a few times 35 or so years back. I do not recommend it unless you like having the jitters the rest of the day.
