Question about Sharp Aquos LC-37GD6U 37 in. LCD HDTV
Several people I've seen here have posted the same exact problem...turn on TV, here small popping sound, NO SOUND comes from speakers. Sometimes it corrects itself by turning TV on and off again...mostly it doesn't work. I found a place to order parts, but I've no idea which sound parts to order, as there are around 6 or 7 of them. PLEASE HELP!!!
I had the same problem on my 37" Aquos. Sound went out about 8 months ago after 4 years. Technician said it was the Sound Power Supply. Total cost to fix was $440. $250 for the power supply and $170 for labor. Has worked fine ever since. When I asked for the old power supply he said he had to give it back as a trade in. I don't believe that so I don't really know if the power supply was the real cause.
Now I've lost sound on 4 channels on my 20" Aquos. Great picture, but wouldn't buy another Sharp product.

OK all, try this as a first step....
First - The usual disclaimer about all at your own risk.
Second - You MUST disconnect the TV from its wall socket and leave it all day (at least 12Hrs) to ensure the power supply is discharged - Safety First.
Third - A major rule of all repair says DO NOT play with or disconnect parts that are working. "If it aint broke don't fix it"
1. Download the service manual... http://www.eserviceinfo.com/downloadsm/31693/Sharp_LC-26D4U.html It comes in 13 parts that must all be downloaded and then the manual can be extracted using winrar or similar program.
2. Ensure you are working in a static free environment - use an antistatic wrist strap attached to the chassis metalwork or you will do more harm than good, you can even kill you TV completely.
3.Follow page 14&15 to remove back cover.
4. Refer to page 56, then re-seat all the connectors attached to the AV unit by partially unplugging them and re-inserting them. Make sure they are re-seated firmly. Do not force anything.
5. Put the back cover on and try see if the problem is fixed, if your lucky the problem is solved.
6, Try gently manipulating the cables around the AV card, sometimes it a simple broken wire. Look up wiring part numbers on page 56 of the manual if you need buy new ones. Parts can be bought here http://www.partstore.com/
7. If not then the whole AV card probably needs to be replaced.
All the parts are listed starting on page 100 of the service manual. Manual says AV card for LC-37D4U is part # DUNTKD352DE19 http://www.partstore.com/Part/Sharp/Sharp/DUNTKD352DE19/New.aspx
If you have a different TV of the series look up the part in the manual.
Hope this helps.

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.

I want to know.
If it is the "sound chip" can I by-pass the internal speakers and expect it to work?

I had the same exact problem with my 37 inch aquos LCD TV at almost 3 years to the date. I called Sharp up and told them I want them to repair the tv at their cost since this was the second time I've had it repaired (first time in 2 months after I bought it) in 3 years. No questions asked and they are repairing it at no cost. I have to give it to them for taking care of the customer, but not too happy about the product. Hope others can benefit the same way. I let them know that others are having this issue and referenced this website. Big dissappointment for a $2500 purchase.

Sharp has set up a special service team to handle the Aquos sound problems. Our 2 year old set's sound went out and I called the Sharp service number (found on the net). It took 2 tries and the replacement of 2 boards, but they fixed it for free. Sharp is taking care of its customers.

UPDATE - from guest who posted on June 18, 08 as solution 4. Three months has passed and as suddenly as the trouble appeared it has cleared!! One day when I turned on the TV the static click that I I always heard was no longer there. I reconnected the TV directly to the CATV and it now has sound!! I don't know why but I am very happy

I have the same problem on my 2005 model. Sharp's help line was in fact NO help. They suggested I call a auth repair shop that was an hour drive away. The shop said bring it in and for $125 he would dgn the problem.
Instead I took the coax from cable company and connected it to my DVD player. Used video cables to connect the DVD player to the TV with no sound and connected the audio cables from the DVD player to the aux input on my stereo. I reconfig'd the DVD remote to turn on/off the TV and use the DVD remote as a tuner and the stereo to control the sound! While the fix is not ideal, it works for now

What 6 or 7 parts are you refuring to?

You can have them repaired using a TV Repair guy but often it costs as much as a brand new tv.
I hate to say this but its often cheaper to just buy a new TV.
My daughter broke my $1,600 LCD. It would have cost $1,200 to fix.. so I just bought a new one.After that I picked up a TV screen protector called TV Armor http://www.tv-armor.com Its designed to protect the TV from damage. Now I dont have to worry anymore when she is playing near it. It works really well.
