Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

SOURCE: Magnavox 30MF200V/17 No picture, only sound

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: Sharp 26'' LCD HD screen went white, sound is fine

Go ahead and try unplugging the video (yellow) cable and plugging it back in.
If that doesnt work, do you have any spare video cables try those.
Then unplug your tv for 2 mins and hope for the best.
GOOD LUCK.

Hi, It is very likely the baclights have failed. If you look closely you might see a very dark image. These can be replaced but sometimes can be a problem to get. Always remember there are live parts inside and if you are not sure it is wise to call a qualified repair technician. I hope this helps.

Magnavox 15mf605t/17 15'' LCD HDTV won't turn on


Have similar TV. If it is set to the PC source, it goes into standby when there is no signal, like a regular monitor. Even though the monitor is in standby, you can still press the Source button to change to, say, HD input, and will use the familiar on/off action when pressing Power on the remote.

A little weird, but I've gotten very used to it.

If the LCD only has coax, it will never display a HD picture quality. However, the Comcast HD Box will still display a picture using the coax connection. So, you could watch any HD channel, but the picture quality will not be high definition.
