I have a philips 42" plasma model number 42pf7320a/37 every so often it will turn off on its own and then turn back on just as if it turned it off. When it was originally under warranty I brought it back to the store they said they changed the power supply but there was never any difference and being fed up with them I never went back. Can any one help. Thanks.

I would cover the remote to verify it is not the cause.

Its not the cause it has batteries we out of the remote
