Re: Sharp Aquos Sound problem
This unit should be under warranty. DO NOT open it up as that would void the warranty. I would try and see if there is a pattern to when the sound fades. This will be helpful to the service center. At the very least, log a service call stating that the problem is intermittant. Then if the problem goes away on its own, but re-appears after the warranty is over, you should still receive warranty coverage.

Yes this is a common problem. You have to have it refered to a TV SHOP. I can fix it for you but in CA. the wiring on the speakers needs to be upgraded to a thicker wire. The gauge is to small for the current needed to flow evenly.
I had the same problem with a Sharp Aquos 40". Sound just for a second and the message all the time in the middle of the screen, no more sound. I opened the TV and found a speaker cable (a black one) with the PVC isolation broken and the wire in contact with the chassis. I just isolated it, the sound came back and no more error message.
Call Sharp for warrenty repair.This problem very common in Sharp tv.Picture will come on turn power on/off button few times will work.But still under Wareenty call to Sharp to replaced the main Tuner Signal board.
yes and no. That particular tv you have is done for, but if you just purchased it 6 months ago, you are still within you 1 year warranty with sharp. they will ask you to take it to a authorized service center and you need to follow through with the process. about a week or 2 will pass and the service center will deem the unit unrepairable and sharp will replace it if they cant solve the problem. give em call..good luck 2u
I have an LC42D64U with firmware U0709111. This is an 11 month old unit. It was working fine until I lost power one day, then I couldn't get any sound. It always showed up as Audio: mono. I tried every setting and nothing (although XBOX via HDMI still played though the onboard audio, so I knew it wasn't a HW issue).
After searching around for a method to change the mono/stereo I resorted to the Fred Flintstone's fix and simply pulled the plug on it. Immediately after turning it back on it worked.
When I first bought my Sharp Aquos 42 inch TV...I started having sound problems...turned the volume way up to 60 maximum and could hardly hear it.
Then after the TV was on for 4 or 5 hours, there would be crackling chirping popping noise. It seems after the TV heats up for awhile...there is MAJOR sound problems.
So I was advised to buy a Sony surround system and connect it to my TV...deactivate the TV volume and use ONLY the surround sound. I did that...but the surround audio cables are connected to the back of the TV and I get the exact SAME problem with chirping and crackling sounds after the TV heats up.
SHARP IS NOT BEING HONEST WITH CUSTOMERS.
There should definitely be a RECALL on the sound board.
Replacing it does nothing....the overheating of the TV just damages the new sound board and the TV has to be repaired again and again.
