    I could try these things if I could only get the back off the TV. Any suggestions? Isn't the problem behind the big middle part of the back? The problem I see is that the back appears to be one big interconnected piece. The part where the cables are just flips open but that is no help. Thanks!

If you had sound from the onboard speakers before and lost it (without changing any settings), then try the main resets in the back by the a/v in and out jacks. If this does not work, call Sharp Customer Service (1-800-237-4277) and tell them that you already did the resets. There is a known problem with a heat dissipation pad for the onboard speakers and they will send a repair tech to replace the pad for free, even if you are out of warranty. At least that was the case with my LC-32D6U.

Is this a problem that just started or has been since you bought the TV ..Try going into the control pannel and checking your sound settings. Make sure it is not set to something diffrent on MTS (Mulit-channel Television Sound)Some times the sound gets switched while programing your TV. Make sure it is not turned on to SAP (this sometimes will happen and you will get NO audio) There should be several settings on these tvs for your audio ..Check to see if the "variable " is selected in "output select ". Also check to make sure your plugs to the outputs are correctly installed and if you have it hooked up to a home theater try turning it on , you may also wish to try to change the settings IE , tv , DVD , VCR ect on the home theater as sometimes they get pluged into the wrong input . If all else fails I would return it to place of purchace or call thier tech support at Sharp , ask for a supervisor ...

    It really sounds like something in the menue got changed , Follow the menue prompts to the "audio" section and try to change it back . If one setting gets changed it will effect the DVD and any other audio out puts you may have including VCRs ect .You do not want to take the back off this will(may) void the warranty ...The above can be easily accessed by following the Menue options on the remote . Checking the wires if they are not "plug-ins" may/will need to be done by certified repair comp, if sharp tells you you can do this get in writting that they will not void the warranty if you do this . But first try the settings via the menue

Sharp Aquos 37" LCD TV sound quit


You could open up the TV and look for signs of burnt components then try to replace the components or try to find a replacement for the entire affected board on ebay or something. If you can find out what the problem is maybe the service person will lower there price. $600 does seem very steap, it should be something closer to $60 an hour with maybe the first $60 as an estimate.

No sound on Sharp Aquos 37' LC-37D4U


Almost all intermittent audio or audio failure problems with Sharp Aquos LC**D4U, LC**D5U, LC**D6U, and LC**D7U televisions are the result of a relatively simple design flaw involving the heatsink pad compound used on the Tripath TA-2024 amplifier chip (IC2502) found on the A/V board. This compound has a fairly low melting point and, over time, tends to seep out from between both top and bottom heatsinks onto the legs of this chip as well as onto circuitry immediately surrounding it. Further, over time the seeping compound also becomes somewhat conductive creating bridges which short the audio amplifier circuit causing everything from intermittent audio to complete audio failure.

Fortunately, in almost every case audio can be completely restored by cleaning the old compound from both top/bottom heatsinks and from both sides of the PC board in the area immediately surrounding the chip (I used rubbing alcohol which worked quite well). Sharp has issued a service bulletin addressing this issue (LCDTV-194) wherein a ‘2502 Heat Kit’ is specified. This kit is Sharp Part Number: PSPKIT663WJZZ and is available from circuitcity.partsearch.com for $19.95. However, it’s entirely possible to get by with the heat pad only, Sharp Part Number: PSPAZA663WJKZ for only $9.95. Please note that board replacement for this problem is almost never necessary, so if you’re working with a repair technician be sure and insist that he/she be certain to try cleaning the old board and replacing the aforementioned heatsink pads before charging you for a new board.

If one is reasonably familiar with electronics disassembly/reassembly and is willing to take their time, this can even be a DIY project. It is possible to find ‘important service references’ by simply entering LC26D4U (the 5, 6, and 7 series are very similar, and this information covers all screen sizes) into the search field at eserviceinfo.com. This will greatly aid in disassembly/reassembly of the TV, as the A/V board is somewhat ‘buried’ under other boards. Please refer to post # 373 at avsforum.com/avs-vb/showthread.php?t=647174&page=13 for pics of the information detailed here.

Particular thanks are owed ‘Aureius’ of the AVS forums for his research efforts concerning this issue !

No sound on Sharp Aquos 37' LC-37D4U


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.
