Try the main resets in the back by the a/v in and out jacks. If this does not work, call Sharp Customer Service and tell them that you already did the resets. There is a known problem with a heat dissipation pad for the onboard speakers and they will send a repair tech to replace the pad for free, even if you are out of warranty. At least that was the case with my LC-32D6U.

Testimonial: "Very helpful. Thanks for the information which might save me a lot of money if it works!"

Press the menu button and scroll over to the setup sub category. Scroll down to reset and press enter. Select yes and then enter. Select yes again and press enter. The television will turn itself off and then back on.

If that basic reset doesn't work call 877-332-7867 to be walked through the no sound troubleshooting up to an INIT. I cannot put the steps for an INIT into print because any wrong move could erase everything from your television.

Let verify first to narrow down to where the problem can be. First, make sure the MUTE or SAP function is not activated, then 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 (Red and White) 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.

Please post back what you find.

Assuming you are using the internal speakers, check and make sure you have the audio enabled. Some TV sets have a option to turn off the internal speakers. Also make sure mute isn't turned on. If you are using external audio setup, double check your connections.

Check its sound settings first. If it is OK, check its speaker. If you wish to get more details about these type of faults, check this link. Pull up older posts there.
