Magnavox plasma tv loses both picture and sound

I have a 42 " Magnavox plasma tv. About every other time I turn it on, it ends up losing both picture and sound. While the 'power' indicator stays on, the only way to temporarily fix the problem is to unplug the tv, so it can reset. The problem may occur again within 30 minutes, or it may not happen again until the next day. Any ideas?

    42 inch Magnovox picture is lost, but sound is okay.  It's not the cable.  I reset.  The picture is dark with lines of color and picture trying to come through.

    No help from Magnavox.....

Do you know if i can use an inverter from any LCD tv, or does it have to be specific to that model? I was thinking about taking an inverter from another broken TV.

SOURCE: Samsung Plasma 42" TV - 2006

Hi, this is quite a common problem for plasma screens and LCD screens. The fluroscent backlight is more than likely faulty and would need replacing. The best thing to do is to take it to a service centre because there are no user servicable parts inside the plasma.

SOURCE: Blinking Red Standby Light - No picture

The six blinks indicates that an internal fan is either bad ot blocked by dust or debris, You should be able to look in the back of the unit and see some cooling fans. Chances are one on them is not turning and will need to be replaced

Adjust the automatic shut off settings on the set using the menu system. the newer models are programmed to shut down to avoid the burn-in problem associated w/ plasma scenes.

The TV turns on and shows a picture that you can watch and within 10 minutes the TV loses its picture, however, the light is still green. If you turn the TV off you can get the picture to come back after...


The issue here could be a capacitor within the power circuit. Also could be a power transistor that is faulty. On the easy part it could be a matter of reprogramming the unit but I doubt it.

42' plasma magnavox model # 42MF230A has no picture and no sound


I had the same problem with an Insignia 42" 1080p. Turn off the tv power and disconnect all cables (i started with power cable, then HD cables then HDMI). Wait 30 seconds with nothing plugged in, then I plugged everything back in (in reverse order) and it works fine.
