This thread is about CRT's (cathode ray tubes), and is for those of us sick and tired of hearing about that other CRT

I'll start out with a listing of some topics about the dangers of fucking with CRT's: - High-voltage/low-current CRT anode (the obvious one) - Medium-voltage/high-current B+ voltage - Live chassis - Tube implosion - Hernias (from lifting the damn things)

Edit: I am not an expert on CRT's, but know enough to be dangerous.

To discharge a CRT you will need two long metal shaft screwdrivers.

Look at the back of the CRT, you’ll see something that looks like a suction cup. Slip one of the screwdrivers under that cap, it will hit the metal prongs in the cap. Use the other screwdriver to touch a piece of metal somewhere in the set, then touch the two shafts together. You’ll get a quick arc if the tube was charged. Rub the drivers together and under the cap/on the metal to make sure you have a good connection.

Once discharged, you can gently pop the cap off the tube. Generally, any metal chunk it touches will discharge and keep it from accumulating a static charge. Be gentle, the risk of implosion is negligible around the cap area, but can still happen.

Don’t do this if you’re unsure of anything.

That's how I started doing it before I got myself a big ol' long high voltage probe. Has a neat little electrode attachment that slides under the cup. Makes awesome noises when actually measuring the anode.

Yeah, the proper tool is always better. I never had the need for a HV probe - only did TV repair when I was in high school, after that I entered a different area of electronics.
