Magnavox 42 inch flat panel cannot get a picture


TV may need software upgrade. Go to menu, find instalation, find software upgrade, find. If version is bellow FL2D-r23 (#23) TV needs upgrade.
Get upgrade on the internet onto a USB flash drive. The file may be a ZIP file, if so, unzip to a folder in PC then put the file to the USB drive.
Turn TV on, plug in the USB drive, wait til the upgrade is finished. Unplug USB drive, turn TV off w/remote.
The TV will then turn on by its self and the upgrade is complete.
Hope this works

Magnavox 42 LCD 42mf438b/f7 turns on/off by itself sometimes screen goes blank tv unresponsive to remote


I have exactly the same problem with a Magnavox LCD 42", very similar model 42MF437B/37. I don't have a solution. If you unplug the TV and plug it back it starts working, sometimes for hours, sometimes for less than 5 minutes, before it turns off again. Does anyone have any real solution?

One of the driver IC'S has gone bad. Need to replace just the driver IC or the board that the IC is on and that should solve your problem. If that doesn't do it, then the BAD NEWS IS THAT THE PANEL IS BAD. Replacement is you only option then. Good luck. GURU JAY.

Is it only one time? If it is out of the speakers this could be going from analog audio to digital audio. It could also just be the cabinet expanding and contracting.
