a short list:

sound on set or a box muted or turned down?

speakers inside the set (see menu) switched on 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 that you have not already done--make sure if Sony the remote 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.

We just got a new cable box and now the Picture works but no sound. The volume is not muted on the tv or cable box. We've tried connecting the cable box three different ways and still get the same...

Does say a dvd player give sound when connected to the same input? If you have determined that the source is good and the speakers are turned on in the menu then I would replace the main board.

I have a picture on my 37" LCD LG Tv but no sound, the volume level moves up and down but no sound is coming out? any ideas please?

First open or remove the cover of the television and check the speaker inside.Check if there's a resistance in the terminal of the speaker.If the speaker is good check the wiring and connector from the speaker to the sound amplifier.Thanks...

I cannot get any sound from my wega KV-24FS120 sony. Sound does not come from TV speakers themselves. I tried MTS and all the audio functions. What to do? Demian

Hi,There are three cause of no sound,ethier the problem is in the speaker,sound driver or output and from the audio setting.First is check the setting, that you already done that what you sad.Now check the speaker if good or not,Use analog or digital tester to check the speaker if good or not or test the speaker to the other amplifier to identify if good or not.If the speaker is deffective replace it and if the speaker is good the problem is in the sound driver.Maybe the sound output ic is deffective or no supply.Thats why it is needed to troubleshoot and repair the sound circuit section of your television.Thanks

Colors Faded in my sony KV-HA21M83A 21''

Its magnetic effect on picture tube. Power Off TV for 20-30 minutes then turn it On, hope problem will be resolved. Please also check and remove any speaker or some thing have magnet near by TV.
If color spots are still there, picture tube need to degaussed / demagnetized.
