Sound problem with Sharp LC-32D4U

I split my audio signal from my HD Cable box so one audio output connects to my Sharp lcd and one to my stereo receiver and have been using my stereo receiver for sound. I want to mount my lcd on teh wall and remove my receiver and use the HDMI connector from my cable box to my HDMI input on my tv in order to reduce the volumes of wiring. When I removed my stereo and connected my HDMI wire, I get picture but no sound on the tv. I also tried to re-connect the component wires from my cable box along with the audio cables and same results. It seems that the only way I can get sound now is to go through my stereo. Is there a setting that I'm missing in order to re-connect the audio?

I got the sound on my LC32D6U fixed for free. Even though the TV is out of warranty, Sharp considers it under warranty for the sound problem. The number i 800-237-4277.

Perhaps you forgot to set the HDMI sound on your Sharp TV.

On your Sharp remote, press:
5. select DIGITAL

    You have an LC32D4U? This particular model is notorious with "no sound" problems. Perhaps your TV is actually the problem.

    Try hooking up another source to the TV such as a DVD player. Do you get sound? If not, then most likely a TV problem.

    I've seen MANY tv's of this particular model with no sound/intermittent sound problems. The cause is a design flaw by Sharp in which the silicon grease they used to cool the audio IC tends to break down and melt after a couple years, shorting out the audio. One way to check for this problem is to turn on the TV. If you hear a faint "pop" noise from the speakers, your silicon grease has melted.

    The only way to fix it is to take apart the TV and clean off the melted residue on the audio ic. Then youd have to replace the silicon grease with a new type of Heat Insulation Pad by Sharp. Its not a particularly hard job, but its just you have to remember where A TON of screws go back on. I would suggest calling Sharp for a local service center. However you are brave enough to tackle this yourself, you can email me at for instructions.

Sharp sound problems no sound

Just check if the audio signal cable is getting into the Sharp panel. If you are using HDMI then select the audio in to HDMI. I am unclear if your audio was previously coming in from the stereo or the cable box. If you have removed the stereo then you need to ensure the audio signal to the panel is stored. Not sure if this helps.

How do i connect audio from satellite receiver into sharp aquos tv

If you are using an HDMI cable the sound and audio will be in the same connector. If you are not then you must run an audio (stereo both L + R) cable from your satellite receiver to the audio input of your television.

If you are using a S-Video cable it only carries the picture and not sound.
In that case it also requires an audio cable as well as a video cable.

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.

42" Sharp Aquous audio; Mono vs. Stereo

no. that is not true. the person you spoke to obviously didn't know what they were talking about. you mean to tell me that everyone that has a cable or satellite box with a stereo or hd tv is not going to receive stereo sound? really,think about it. you only need a cable box( for now ) if you have premium channels (hbo,showtime etc). you can connect the cable line right into the tv if you only have basic cable. look at the back of your cable box. if you have a red, white, & yellow audio/video output, then the box is stereo.connect these outputs to your tv. this connection however is not will need a hd box with a hdmi cable for hd .To put the tv on stereo mode, there should be a way via the menu and/or the audio button on the remote to get it off mono and put it on stereo. your manual should at least show you around the settings of your tv.

No Sound

When your turn on your TV, do you hear a faint popping sound from your speakers? If so, the heat sink underneath the audio IC has melted and is shorting the audio circuit. Its a complicated job, suggest contacting your local sharp authorized service center.
