The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.

There should be a conductive coating on the outside of the tube (old duffers would call it "dag", from the coating's original trade name, Aquadag) with a copper braid harness to ground it to the circuit board. Discharge the HV to this.

I would see what others have to say befor doing this but, when my 40" CRT tube TV died, it sat out for a day. We ended up jamming a screw driver into the ground, with a wire connected to it, with another screw driver at the end. We then poked under the suction cup and after that I ripped it off. So for my case, the tube was successfully drained. But, some CRT tubes can hold charges for years, others will drain out in a couple hours to a day..
Another option is to simple chuck a rock at the screen and clean up after wards. That discharges the tube real easy :D if you don't mind a mess.

just poke around with only your right hand until you're pretty sure it's all safe. i think you're more likely to get hurt by the muscle spasm causing your arm to fly into something than by the charge itself

lol it was kind of bad advice. just wanted to reassure you that you probably wouldn't kill yourself if it wasn't discharge properly. hope you find some cool stuff in the tv. don't forget the degaussing coil

I didn't forget the de-gaussing coil It's the biggest TV I've stripped in a while.....half a dozen biggish heatsinks, big flyback core, and some other interesting stuff, high wattage resistors, biggish electrolytics, other big capacitors, rectifiers, transformers, chokes, other inductors, not looked for diodes yet. (biggish transistors, but not identified them yet.)
(I've kept everything except the CRT and the plastic case (as usual), including the yoke, which, while it can be tricky to strip, yields lots of usable enamelled wire. I'm hoping the speakers will yield the thin wire for my 'moving coil meter' project.)
I normally don't bother discharging them, as they've usually been switched off for sometime before I strip them, but due to the size of this one, and the fact that it had only been off for a few hours I didn't want to take any risks.

Discharging a TV
Which means I can strip it for parts
