    I have exactly the same problem with my LC-37D6U. Saw a part on eBay: Sharp PSPAZA663WJKZ INSULATION PAD
    Sharp Part Number: PSPAZA663WJKZ
    Would that be what I'm looking for? My model is on the list of models it works with.

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.

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.

Sharp Aquos LC-26D4U sound problem

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.

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 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 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 for pics of the information detailed here.

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

Sharp LC 37 D6U

That popping noise means the silicon grease underneath the audio ic has melted and is shorting the audio. This is unfortunately a design flaw by sharp. To fix the problem, you'd have to disassemble the entire TV and clean off the melted residue off of the AV Board and replace it with a new Sharp Heat Insulation Pad. Its a pretty difficult job, I suggest calling your local Sharp authorized service center to fix that for you.

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.
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.
