Check whether there is any sockets marked as line-out, at the back of the set. If yes, you can connect these sockets to an external amplifier to make audio more louder. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter".

My Sharp Flat Panel Television LC19SB25U has Picture but No Audio


Sharp has had a few problems with their audio boards, not finding any bulletins on this model, but a few complaining about low audio on amazon reviews section. If using an antenna you will experience some channels with low audio. If using cable you should get good sound on all channels..
the 9.1 and 9.2 are digital channels and sharp does display them for at least a few seconds when you switch to that channel. Check all your setting in the audio to Stereo never SAP. To options for you are get a cable box, first check in the back and see if there is another coax in, if there are two try both rescanning after connecting.
