Dear eldest daughter lives in Boston and has an annoying TV problem –
Mitsubishi TV works fine when playing DVD’s – – when using the cable service, the video works fine, but the sound has problems – turn it on, the sound is fine, then as time passes (5 min or so) there begins a buzz with an high overtone, progresses till there is no program audio – turn off the TV, count slowly to 10, turn it back on and the sound is fine – for a few minutes when cycle starts again –
I have suggested she make friends with one of the neighbors and borrow a TV long enough to acertain whether it is a TV or Cable problem or TV/cable interaction problem –
cable co is not particularly interested in the circumstance –
anyone have any suggestions?
thanks –

Or bring the TV elsewhere.
We have a problem, intermittently, only on one set with one channel with the audio. All the t's and s's are horribly scratchy staticty sounding. Don't know how else to describe it.
Cable company could care less.

thanks, Eric - it would possibly be the easier/smarter strategy -

I have the same symptoms from time to time. Older tv, with a separate DVD and VHS players. When the sound get funky (exactly as you described), I jiggle the audio input cable from the DVD to the TV. Fixes it immediately every time. Probably just a dirty connection that a shot of contact cleaner will probably fix once and for all.
thanks, RedHen - the girls have done some fiddling with the wiring, but I'm not sure what exactly -

What kind of inputs do the cable box and DVD go to? If one's baseband RS-170A video and separate audio (RCA plugs), and the other comes in NTSC channel 3 or 4 (screw on F-connector), it could be in the TV set.
As a test, could you find a way to use the same input on the TV for both, plugging them in one by one? If the symptoms remain the same, then it's the cable box that's at fault. If either both are good or both bad, then it's the TV set.
If cable's the problem and they won't fix it, cancel and go satellite. If the TV set is the problem, bear in mind that NTSC is supposed to go off the air in, IIRC, February of 2008. You have to consider whether to go with a cheap TV for two years use, or buy a new digital HD set now, while prices are continuing to fall.

ya - this is the most likely possibility, but before they spend money.... I can just see bringing in a brand new set and having it act the same way -
I'm not sure of the specifics, but it is an 'older' set, and they don't have the original remote/instructions to access any menu (if any) associated with the set - -
it's a 19" set that can be replaced for $100, so it's not that big a deal, as long as it cures the problem -
the change coming has been on my mind also, as I look at my 1985 'Technica' which with I am very comfortable - <sigh> - looks like either another box or another TV - -
thanks for the info, I'm going to copy and send everyones suggestion -

David. We have a cable box and a remote for it. If you push the cable button on the remote, you adjust the cable volume. If you push the tv button on the remote, you adjust the tv volume (you have programed the remote to your tv.) If you bump the cable volume too high and the tv volume is low, it has a consistant hum. Don't remember it coming or going, but the diff. I noticed was dvd's would play alright (no cable).A great place for Information, Comraderie, and a sucker punch.

It's probably the set -- the AFC is drifting off-channel as it gets warm. However, it would be worth double-checking that she has it set for "cable" vs "antenna", as you can get some buzz (and fail to get some channels entirely) if that's set wrong.
(Though I'm assuming that this is a "cable ready" set. If not then the cable box may be wonky, or, if this is a really old set with analog tuner, it just needs to be fine-tuned a hair.)
happy?
