When discharging the tube, should I first :
1. disconnect DC, disconnect all wires linked to the chassis (neckboard wire, rotation VL connector, coil, video), then discharge the tube, then extract the sucker?
2. disconeect DC, first discharge the tube (screwdriver trick), extract the sucker, then disconnect all wires linked to the chassis?
Also, when doing the screwdriver trick, should I insert the screwdriver under the sucker deep enough until I touch the metal pin of the hook?
I heard about some recent monitors (since when?) does have an auto discharge, I don't know if mine does (Nanao MS8-18 series chassis/Mistsubishi tube), but usually I always disconnect DC and all wires first, then extract the sucker with gloves. But I never discharged the tube with the screwdriver trick before.
Today, when mounting the chassis back to the tube, after I have reconnected all wires (except DC of course), I was putting the sucker back and an electric thunder appeared, then I felt a little electrocution. Now I'm worrying, so I better have to discharge the THT before with the screwdriver stuff...
Usually I wait 12h before extracting the sucker, then I touch the tube with a screwdriver (I ever thought we shoud do it that way but now I know it's a silly habit) and I never had any problems. Maybe because usually I do this after having disconnected all wires linked to the chassis, but I'm not sure.
But recently I read that 12hours isn't enough, since a tube can keep the 20000V during years.
