switching the monitor on while unplugged from the mains supply, (if you can) may discharge the PSU capacitors, but not the tube.
discharging an anode cap, that long wire with the sucker thing that goes into the CRT is easy to do if you are extremely careful, i usually use a real insulated/shielded screwdriver with some heavy gauge insulated wire, you connect the wire to the chassis or metal frame of the monitor or a strong grounding point , making sure its all unplugged and isolated, and slide the screwdriver tip carefully under the cap, itlll spark loudly, dont touch anything other the insulated handle of the driver, dont rest your other hand on the monitor etc. do it a couple of times, when it stops making sparking noise, hold the tip there a while, then leave it for 5 minutes and do it again,
Theres 24 kv inside that CRT, enough to fry anyone
