I had the "guns" in my 12 year old Magnavox projection TV serviced last week, fluid drained, flushed, cleaned, aligned.
It was just like a brand new TV.

This morning my wife was watching the news before she went to work and the TV picture went pffffftt.

First I thought it was the DTV box or a cable connection.
Hooked the cable up to the laptop and got a picture, so it's not the DTV box or the cable.

Tried the rest of the units hooked into the set, the S-video stuff worked.

Troubleshot it for about 10 minutes and found that the cable input to the TV is fucked.

The S-video and the two rca jack aux ports work.
So now I don't have PIP, stereo or surround from the TV as only the cable side allows it.

$200 to service the guns that I could have spent on buying a new TV....
The guy that serviced the TV was joking (perhaps not) about people spending money fixing TV's when they should have replaced them.

I was looking at getting a widescreen 42 inch Panasonic tube TV, but the wife "talked" me into fixing the old TV.

Fear not. This is just God telling you that TV is bad. He does that from time to time.
