Question about Sharp Aquos LC-42D62U 42 in. LCD HDTV

2 Answers

No sound I have video but no audio. From the menu screen, I have changed the output select on my Sharp Aquos LC-37D6U model TV to "fixed," following the manual, but I still cannot hear any sound. Would you please let me know what else I can do to fix this problem?

Re: no sound

When you turn the tv on, do you hear a faint “pop” noise from the speaker? If so, the problem is with the heat sink under the audio IC. Over time, the heat sink will lose its consistency and start to melt, thus shorting out the audio circuit. To fix, you’d need to clean off the melted residue on both sides of the audio IC as well as replacing the heat sink with a newly redesigned Sharp Heat Insulation Pad. It’s a pretty complicated fix, I suggest calling your local authorized sharp service center to fix this problem. The part is inexpensive, so you’re most likely looking at a labor charge (maybe around $200ish) for the repair if they are not marking up the price too much.

My sharp aquos tv LC-60LE632U has picture but no sound, What can be done?

Check the audio 'output select' under the Systems Settings menus. The output may be set to 'variable'. Set it to 'fixed' so that the audio runs through the speakers.

Aquos LC-32D43U, no audio

My suggestion would be to bypass all of your video components whatever you have be it a vcr, dvd player,whatever and just hookup the tv direct to whomever you receive your cable tv from. Because it was working before you moved it and disconnected the external audio source. Remember if your using HDMI cables they are your audio and video together and you don't need to hookup anything else from that device to the tv. Just FYI. Good luck.
