    It happens at all different times. I can have the TV off for a hour, up to five hours and it will come on by itself.

    Some plasmas have a feature called standby mode upgrade. It can usually be found under menu-Settings or menu-> System. If I am not wrong it happens after the tv is off for about half and hour?

    - Ok. Since you have rejected my solution I assume that you are not willing to solve your problem. You could have just said that it happens randomly. Good bye

    I am willing to solve my problem if that was the solution. I don't believe I lead you to believe it happened anything but randomly.

Hello,

if your TV turns on by itself, then it means the fault is from your power button/switch. The power switch might be stuck to the "on" part of your TV and it contacts even when its off.

Constantly press the power button of your TV, as it might free the stuck power button/switch.

Or maybe you will have to remove the TV plug from the wall when you turn if off, so that it won't switch on by itself.

Take care.

I can't operate my Philips Magnavox 42MF521D/37 Television


Philips has the FAQs and manuals for the 42MF52D/37 here: http://www.m4c.magnavox.com/cgi-bin/cpindex.pl?ctn=42MF521D/37&mid=Link_FAQs&scy=US&slg=AEN . The direct link to the User's guide is http://download.m4c.magnavox.com/files/4/42mf521d_37/42mf521d_37_dfu_aen.pdf . You will need Adobe Reader of a similar program to read the manual.

Is there a specific problem you are having with your set? (OTA or cable setup or another issue) Please add a comment if you would like additional support. Note: digital OTA signals are subject to a "cliff effect" if your tuner doesn't get enough data from the antenna. This will be determined by the tuner, the antenna location (indoor, outdoor, elevation), distance from the transmitter, and any splitters or other wiring problems. I've seen failed amplified splitters turn into filters that block the incoming signal from reaching the TV.

My magnavox 42mf521d/37 tv stopped working.


First place to look is to follow the power cord inside the set to the main fuse---look at that first. If you are not able to do that get a shop or tech to look for you.

My Tv model number 42mf521d/37 will not turn on and makes a high pitched alarm. What is the deal. Do I need a preist? lol


Is the TV's name Damien??
I think it's the main power supply. This happens far too often on new sets.
