After being on for a few hours, my TV shuts down. I have called my cable company and they said it is a short in the TV. I have unplugged the TV with the cable line and plugged it back in. It comes back on and is operational for a while, then the problem comes back. I think it's the cable line running from the TV to the box. HELP!!!

My Viewsonic 4785P is out of warranty. Problem is showing in different ways: image stays but sound goes then comes back, or not; everything shuts down and then comes back, or not; other times there is a very strident sound as if the set will explode. A tv tech suggested on the phone that the mother board could be either about to die or corrupted by my cable device and advised to shut down everything for 24 hours. Went very nicely then ... for 3 days and the same thing starts same way again What
A problem like this can be caused by RF interference. Shut it all down again and move the converter, any cordless or cell phones, wireless PC's, routers, etc. so nothing is within 3 feet of your set. A poor ground on your converter can also cause RF ...

On my HD1080 Mitsubishi projection flat screen the picture is bowed on top and bottem and it look as if the projectors themselves are offset, but the picture is clearer as you come toward the center. If I smack the side the picture will sometimes come back into focus. But the picture will soon after go back out of focus and sharp swiggly lines streak across horizonally. How can I fix this problem and how much might it cost.
You have poor contacts and or dry joints. Resoldering on the convergeance panel and powersupply/line timebase board will probably fix it.It should take less than an hour in labour terms. ...

Second problem is audio with the Toshiba. Thru the cable into the turner...snap..crackle..pop. Using the video 1 & 2 inputs, the audio is fine. Im thinking on this one the cable hook up on the tuner broke loose. And finaly the picture has the slightest tilt from left to righ

As I switch on my TV LCD Samsung (model LE37A656A1FXXC), some vertical coloured lines (semi-transparent though) appears in the left-center of the screen. After more than 30 mins they disappear and they come back from time to time. Unfortunately my warranty has expired. Someone says it's a problem with the T-CON Board. Could you help me find a new one or suggest me how to fix the problem? These are the numbers I've found on the board:

On cable channels that have no comercials, it will stay on for an entire movie and then begin again when the comercials start. When playing a DVD it will cut on and off at the beginning, when previews, e

I could turn it back on with no problem. That time period kept getting shorter and sometimes it would take 2 or 3 tries to get it to come on. Once back on it would play until I turned it off. Now it only stays on for about 30 seconds and I can't get it to restart. If I wait and hour or two it will come back on but only
