Flatron w2242pm no sound

do you have speakers on your monitor? If yes, check the wire connecing hte sound to the speakers

flatron functions only as video monitor, audio is run or provided through a separate device connected to CPU computer or other sources connected to video player.

Sound issues and answersa short list:

sound on set or a box muted or turned down?

speakers inside the set (see menu) switchedon or off?

internal/external switch somewhere in or on back of set?

Clearly it could be a audio problem (a model number?) but explore all here thatyou have not already done--make sure theremote set to TV and look for a button on it marked MTS and if there cycle it.

You can also determine if same trouble when you play a DVD.

The fix for horizontal lines is the same as the fix for vertical lines.

connect audio output (RCA Jack white n red color) from the video, to the audio input of your TV. Make sure you use same AV channel for the video and audio.
i.e AV1 or AV2 or AV3

If you have sound the problem is most likely the LCD panel but if you have no sound then it is going to be the main board.

The LG Flatron W2241T does not have speakers.

It sounds like your Backlight Fluorescent Bulb is burnrd out.
