Default Bad connection on tv

On 9/5/2009 5:36 PM Puddin' Man spake thus:

Any ideas on how to approach it? Just workbench it and start
disassembling stuff? Cautions other than about the 20kv "gun" at the
back of the CRT? Etc, etc.


To begin with, you could probably do with a little high-voltage
precautionary education before you seriously zap yourself.

The high voltage isn't at the "gun" (actually the tube socket) at the
back of the CRT: it's at the anode, which surrounds the tube and has a
high-voltage lead connecting it to the rest of the set. This acts as a
giant capacitor which can store a lethal charge.

Others here will tell you more. But learn up about HV first.
