I am planning to upgrade the internal hard disk of my rev.2 eMac (ATI Graphics, 1GHz) from a 60Gb to a 160Gb and at the same time install a Pioneer 109 DVD Writer. I'm fine with everything about doing so, except for one point. Discharging the CRT. Having only worked on G3 and G4 towers before, I have never come across the need to discharge a CRT and to be honest, am a bit flummoxed.
I have read the Apple Service manual for doing so but unfortunately didn't find it very useful. Could someone be good enough to let me know (simply :P) how to do this. Oh, if it helps, the computer will be turned off for about a week or so before opening it up (as I will be away on business and buying the parts while I'm there) and I don't have a proper CRT Discharge Tool as they are quite hard to find in the UK.

Heres a easy way.Unplug it for 24 hours. Use a long plastic handle flat head screw driver with a wire on it that can lead to a metal bucket sitting on the floor. You also want to use only one hand when doing this for just in case. Do not touch the wire at all also while doing this. Also make sure the screw driver hits the metal connecter under the little rubber cup on the CRT. If it sparks or arks don't worry, it means it is discharged. To remove the rubber cup just wiggle the screw driver up and down in a angle then it will pop off. Also if you live in a dry/cool climent you might want to connect a wire to the metal object you used to ground it for just in case it wants to charge back up.
A lot of people claim that CRTs and TVs discharge on their own after they sit unpluged for 24 hours. Not ture, they can hold a charge for a whole month. But by then it would be as strong of a charge to kill you.
