The screwdriver method can be used to disch the CRT. (A series resistor around 1M helps prevent dielectric bounce back).
The HV isn't dangerous unless you have a heart condition. The voltage and charge stored on a color CRT is slightly less than the worst that of a bad static jolt from shuffling on carpet and touching a doorknob. Voltage doesn't kill current kills...30mA to be precise. A color CRT only draws 1mA max and a monochrome 1/3 of that... the HV winding of a flyback is not able to source lethal current. 400V B+ in your stereo amp designed to source 150mA all day on the other hand can absolutely kill you. I've been bit by live and stored HV countless times and haven't been harmed, B+ is more dangerous than the CRT HV lead.
