You dont need to discharge anything to do some soldering . The charge is
held up under that big suction cup on the picture tube . Simply turn the
set off and wait a few minutes for the filter capacitors to discharge by
themselves , turn the board over then solder .
In some cases when you walk up to a tv and touch metal parts you may get
a static zap just like you do from the car door or door knob in your
house .
