In the audio properties, or audio adjustments. Make sure the speakers are turned ON. Can you turn the volume up with the buttons on the TV.

Check the speaker/s first. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

try a dvd to see if sound via the audio/video jacks and also look in set menu to see is speakers are turned OFF or not, the sound if works with a dvd means it is a hookup or similar issue and the audio circuit in the set is good. Also if set has headphone jack see if that works.

Check the audio output section circuit and speakers for fault. You must have sound knowledge in electronics to check the audio output circuits.

check to make sure speakers not turned off (audio menu) and get up to check if any sound at all from speakers as sometimes the plug inside will come loose disconnecting the speaker/s


Other than that you may have a problem in the audio circuit and that might not be economical to fix

Do you have a "Variable Audio out" jack on the back of the set? If so use that.

Hello,

Let verify first to narrow down to where the problem can be. First, check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. To get the sound repair, it can be from $150 and up, so if you can put up with using the good set of Powered PC speakers which actually give better sound than the tiny speakers inside the TV, I would keep using it that way, you may want to find out if the on screen sound setup will allow you to set the audio line out to be VARIABLE which means the sound output feeding the PC speakers can be varied using the TV remote control, then all you have to do is to set the PC volume to about half way up and set the TV volume to what ever you want.

Hoping this will work to solve the problem..
