This problem has been getting worse for the past couple of months - everytime I try to use the TV, after a few minutes, the unit suddenly turns off, then on again, then off again immediately, and on, looping like this endlessly until I hold the power button for a few seconds to turn the unit off completely. All my other devices (DVD, Playstation, sattelite box) work fine, so it's not a power fluctuation. Is it something that's worth repairing, or should I get a new TV? This unit is only four years old. Thanks!

This problem with your television set is more than likely a problem with intermittent component failure. The fact that the television turn on for awhile is a sign the the component or components are intermittent.The reason the television turns off is that it goes into the protection mode caused by the intermittent component or components. They are unstable and are causing unstable voltages supplies to appear in the circuits. The television has a built in feedback circuit that will detect the faulty operation and turn off the television. When it stabilizes again the television turn back on. This is usually a sign of aging or faulty components. The problem will only get worse and the television should be thoroughly tested. You can call Magnavox customer support at this telephone number 1-800-705-200. Give them the model number of your television and tell them about the problem you are having with intermittent turn on of the television. They will be able to tell you where to take the television for testing and service. I hope this information helps you with your problem.
Most likely your Cathode Ray Tube or CRT is going bad. That model number reflects an older TV. What you are describing is a fairly common problem for that television. If you bump the TV and it improves or gets worse then you know there may be a short.. Either way, I would recommend that you use our Premium Service or use our online resources to find a repair person near you. Good luck.
the fault you are describing sounds like what we in the trade call dry joints, basically where components are soldered into the circuit boards in manufacturing, the joints become brittle and crack thus forming a poor connection which can vary with heat. well worth repair may need a couple of electrolytics aswell but i could do the job myself safely for under £100.
