Screen goes out but sound remains

My wifes uncle has a Philips magnavox 17mf200v/17 television and the screen comes on for a few seconds/up to 3 minutes when you first turn on the television but after that it shuts off and only the sound remains. can anyone help? I thought it might be a fuse but since sound remains i thought against it, and would like a few opinions/sugestions. Any help is appreciated.

A blown fuse would not be intermittant.

It is possible that the back plane lamps, and or the back plane power supply is failing.

When the set is in the dark screen, shine a flashlight on the screen at an offset angle. Look carefully and see if you see the picture images. If so, this proves that the back plane lighting is having a fault condition. If there is no image at all, then there may be a fault condition with one of the drive boards for the picture processing or the screen itself.

My magnavox 42mf438b lcd tv will be fine for about 10 minutes when i turn it on, then the screen goes completely black but it still has sound. it stays like this even if i turn it off and back on. i can...


that set is highly rated by users .. it first came out in early 2009 (i think) so you might check to see if any warranty remains ... the display is illuminated by several lamps .. each lamp has its own high voltage inverter .. all the innverters are powered by an output of the low voltage power supply (often 18 volts)... i would suspect a problem with that low voltage power supply.. either a bad capacitor or a thermal issue .. .. ..

My Magnavox 17in LCD TV (17MF200V/17) shows message ''Attention OSD Main Menu locked. cannot use any functions on tv. i.e., volume , menu, etc


It means that some kind of parental control feature has locked you out of the On Screen Display menu. You will have to consult your manual (possibly online) to figure out how to reset the password.
Although it is possible some other kind of malfunction could cause you to lose menu control, this is the most likely cause.

Could your remote possibly need new batteries? Sometimes remotes act erratic when in need of them. Check that out and see if that is the reason for your problem. Luck!
