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?

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.

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.

yes...the video card could have gone out but most likely you have a connection that is loose or bad. I would check those first. If you have done so then I would try another video port and verify that it is the screen that is out and not just the port you are in.

I was watching tv a few nights ago and then I heard a loud "popping" sound and my tv just just off. Now when I try to turn it on it sounds like its going to start but turns off instantly. Does this twice...

the same thing low voltage supply, if there is no blown up capacitor then hold all supply capacitor then shake it a little while, if you ca notice that there's a lose of that capacitor remove it,it might the leg is lose or cut already.

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.
