When you have no choice but to work in a monitor, you should discharge the capacitor using a high-voltage probe. The probe has a ground wire that is clipped to a ground and the probe is inserted under the edge of the high-voltage cup until the charge is dissipated.

Correct Option(s):

a) You should discharge the capacitor.

Incorrect Option(s):

b) You should use an anti-static wrist strap. - Using an anti-static wrist strap while working inside a monitor is an electrocution hazard. Anti-static wrist straps will attract the electricity from a high-voltage device causing you severe harm.
c) You should use an anti-static mat under the monitor. - While not a safety requirement, an anti-static mat could attract the electricity from a high-voltage device. If you were to touch the mat while the electricity is attracted to it, you could be severely harmed and possibly killed.
d) You should make sure that the monitor is plugged into the computer. - Keeping the monitor plugged into the computer is not a safety requirement.
