The capacitors aren't the problem as stated above. The CRT itself is a very large capacitor (stores charge) and can knock you on your ass for a long time after the tv is unplugged.

Also, she's weird.

Yeah, my old boss got shocked by the CRT discharge and his arm swung against the side of the wall and he got cut really bad. It has about the same effect has getting shocked by an ignition coil from a car. I had a similar situation while working on a tube amplifier (around 600V).

High voltage DC will basically burn you really bad (provided it has enough current), but unless you have heart condition it probably won't kill you. It will defibrillate you and wake you up though.

High voltage low frequency AC (between 30 and 1000hz) is deadly starting at around 45 volts. As you get into the higher frequency AC voltages it has less affect on your heart, and thus less likely to kill you.

I saw a chart once in physics class that showed the lethality vs. frequency of AC. The peak was at 50 Hz--right where Europe put their power supply.

I got bit by 277VAC 50Hz once--burned a 1/2 inch hole 1/4 inch deep in my arm.
(I wish we had the metric system in the old USA)
