I have a 1991 Sharp TV 19TB33 and all of the sudden the picture flattened
down to about a 2 inch thick strip in the middle of the screen. I can do
most repairs, altough it's been a while since I've used my electronics
skills. I pulled the back off the unit and didn't notice anything obvious
in the sense of a blown part. Although not sure where things are located
on the board, and was being quite wary of the CRT. I've been electrocuted
when I was a kid and it wasn't any fun. So I'm real causious, but also
know that there are right ways of doing stuff. And on that note, would a
CRT discharge tool for a Macintosh monitor work for discharging the CRT on
this or other TVs?

Could someone point me in the right direction of what I need to look for
and where I might get a schematic?

Thanks in advance.

Scott
