Magnavox 27MS3404/17-Turns off at random

My TV was fine for 6 months until it started to turn itself off at random with the power still on. It continued to get worse. Now when I turn on my TV it shuts off with 5 seconds with the power still on. Is there a fix for this?

    my set turns off just as the sound comes on. If I turn it off the on it will power up, or did, now I must turn it off the on about 48 times before it stays on. during the last ten or so turn ons the picture is wavy on the right side of the screen or just a little shy of filling the screen at the lower right corner. un til the screen is completely filled, it will shut off. why are so many televisions having the same problem? Chinese parts?

    why do so many people have the same problem? I remember televisions last twenty years with no problems? Chinese parts?



    Mine must be turned off then on again 48 times before it takes. When
    the picture finally fills the whole screen including the lower right
    corner it will stay on.

There is a component in the power supply or one of the scan amplifiers that is going off value, and thus causing a protect or shutdown condition.

Take the set back for warranty service, or have it serviced if it is out of warranty. This is not something you will be able to fix yourself.

Mine was doing the same thing. Update the firmware and it fixes the problem. Updating the firmware is done by downloading the file to a thumb-drive from the phillips product support page then plugging in the drive into the side of your television and turning it on. See your manual for slightly better instructions.

T.V. turning on


yes my 26" sharp aquous LCD does the same thing, turns itself off and on at random times without explanation. I sent to authorized service center they replaced the power supply under warranty then it failed within 6 months and neither the repair center nor sharp will do anything about it other than sell me a new powersupply for $425.00. I have contacted a power supply repair center in Texas who has vowed to fix it once and for all. We'll see in the next week if they fix it or not.
