Before starting, I should mention that I don't have the repair experience of
the other posters on this board. I've no hope of repairing this problem
myself, but I'd like to get a rough diagnosis and a handle on how expensive
it would be to have fixed. Please bear with me if I say something stupid.

Last night, my Toshiba CF27G30 started having periods of humming, popping
static pop onto the audio accompanied by white static-like horizontal bars
flickering about the picture. (The static sound is hard to describe -
it's not the soft, steady sound of continuous static, but like the split,
sputtering audio heard when you have bad reception or you're trying to plug
the cable connection into the TV but keep missing the mark by just a little
bit.) I at first thought it was just a cable problem (I live in Montana;
we've just had a snowstorm, and the temperature had reached -30 degrees F
the night this problem first appeared). When I tried to watch a VHS tape,
though, the same audio and video problems occurred. No problems appear,
though, when I flip the display from TV to Video mode to watch a DVD - the
TV works A-OK.

The problem occurs intermittently - it'll happen, go away for 2 minutes or
10 minutes or whatever, then pop up again. I've checked the connections,
and they *seem* tight. The TV didn't sustain any damage or blows or whatnot
before the problem started occurring - nothing out of the ordinary
happened (besides our -30 cold snap, of course, but that was outside). What
could be causing these new audio and video problems? (I should mention that
we probably won't be using this TV in 2 months (not because of any other
technical issue - it's a long story), and it'd be a pain in the neck to
get a new TV and use it for such a short period of time.)

Any help would be greatly appreciated. Thanks very much in advance.
