I would contact the place where you purchased it and check into the possibility of returning it. f you don't have any success I would contact the manufacturer. Most retailers will honor a return on a defective set.

Magnavox 42 LCD 42mf438b/f7 turns on/off by itself

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.

Yes. Its probably a stuck button on the TV's front panel. Try pushing or wiggling each button on the panel. It could be the channel up/down buttons or volume up/down, menu, etc.

When there is a button that is making slight contact, it keeps the microprocessor busy attending to the command its erroneously receiving from the offending button and may not allow other functions to work when this occurs.

It doesn't matter which button is stuck, any of the symptoms you describe can happen.
