Have you checked your Menu in Audio mode to make sure internal speakers are not turned off. Or that you are not in external sound mode. Also Sharp has previous problems with sound board mounting in the chassis as the heat sink strip on the main audio ic touches the metal sheilding and causing audio board to fail. Check with Sharp for updates and service bulletins to your model, they my repair this at no expense to you.

No sound on my sharp aquos lc-45gd4u 45 in


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.

Have picture no sound did a reset nothing


Hello,

The reason you have pictures and no sound might be as a result of a sound IC or that the volume is too low or on mute.

First check the volume to see if it is okay or on mute then correct that but if it is not, then it is a faulty sound IC that is causing it, so try to dismantle the television and replace the sound IC.

Then the television would be in good conditions once again.

Take care

No sound


On your remote you should have a mute button. Or some will cancel mute when you press volume up or down. Make sure you are using the TV remote and not the cable or dish remote.

The sound goes off intermittently


Forget Sharp's defective speakers. Connect your sound output to powered stereo speakers and disable the internal speakers (look through the TV's menu). The operator's manual explains how to disable the internal speakers. You'll be able to control the sound normally (mute, volume) with a remote control.
I connected my stereo output (2 RCA plugs) to an old boom-box and I get better sound than with Sharp's built-in speakers.
