[rescue] What to do about fuzzy screens?

[James Fogg]

Once upon a time in a land far away, a young lad was carrying a color TV (sans
cabinet) out of the local junkyard. He had planned to scavange it for parts.
All of a sudden he felt something akin to a good punch in the jaw. He awoke
some time later. It was dark and raining. His jaw hurt. There was a recently
broken TV chassis scattered on the ground.

Some time later he leaned about the capacitive storage of CRT's, the
many thousands of volts present in the envelope and the tendency for voltage to
seek ground. He remembered his day in the junkyard and wondered.

I still sweat the details around CRT's.
