Help!- Broken Pots
Davestar:
Jay,
How do you ground your HV out? Do you use the screwdriver to ground (chassis) method, or the transformer method? I'm not feeling too confident about either. Should I discharge if I'm swapping out monitors? I was thinking of just getting a new monitor, and swapping it out using a thick pair of welders gloves for insulation. Any thoughts?
Also, is installing a new monitor a major headache? It looks like 4 bolts, and a few wires, to unhook, and then reconnect. Is that right?

The screwdriver method is the only one I know. I use a high quality Xcelite screwdriver that is 12" long with a very narrow (#1) tip. The a "Heavy Duty" jumper lead from Radio Shack.
I also take the HV lead and stick it's metal tip in a screw hole on the chassis. I have heard of that recharging itself without power being applied. Capacitors... Also the picture tube will almost always recharge itself. You can simply and carefully stick the screwdriver in the hole to redischarge it. Don't jam it in or you could damage something. The idea is to simply touch the metal inside with the screwdriver.
I never bother discharging a monitor to swap it out. BUT while holding the metal chassis, DON'T touch the HV wire with your arm or chest or whatever.
Any decent leather glove will do. I use them, not to protect from voltage, but to protect from sharp metal.
It pretty much is 4 bolts and a few wires.
Other safety concerns:
Wear eye protection! If you drop the monitor it could implode. And that SOUNDS ok. BUT! Glass will probably still fly around abit. I have seen people that work on TVs wear full face shields. Use your own judgement.
The neck on the picture tube is EXTREMELY FRAGILE! I have seen many broken. Sometimes the slightest bump, will break the glass due to the leverage you have at the end of it.
Disposal. If disposing of a picture tube or whole monitor, you should break the neck. The prefered way of doing it is to throw an old blanket over it whole thing and the place a 2x4 or other suitable board on the neck, then turn your head as you step on the board. Otherwise kids in your neighborhood will be throwing rocks at it and will some how manage to implode it.
I hope this helps without making you too paranoid. I seriously doubt a monitor will kill you, but I KNOW they will send you to the hospital! Just Be Careful! ;)

Thanks for the reply. I'm really leaning towards replacing the monitor.
