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.

Sharp 20" LC-20B4U-SM


I cannot say pariculary for this model, but on some models of TV sets, if the channels are not programed as part of the channel list, they are muted.

Turn on the TV, and perform the channel auto setup.
