Audio sound comes and goes on my Sharp TV. Understand lots of people are having this problem. Does anyone know if it can be fixed at a electronics repair shop or is the repair to costly and I should replace a 2 yr old tv?

    Rumor has it that there is a service bulletin from Sharp about the PC board needing replacement to prevent sound interruptions.  This cost about $350 parts and labor if you dont have a service plan.  I am not sure if this will fix the problems anyway ... since a new TV cost only $650  (I paid 2200 2 years ago!!!)  you might want to just buy a new set or upgrade to a better newer version.

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 !

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.

I'm getting sound from my sharp tv when hook uo to my blu-ray player


If I understand when the blu-ray player is connected to the set you get the TV sound or what? If properly connected by way of a set of rear audio/video or component jacks to the same on the TV--you should if change the TV input to that location see the blu-ray and hear sound it sends out.

Component, composite, or what is the hook up between the two units?

Sharp AQUOS LC-52D62U LCD TV


Sharp lcd screens are very easly damaged especially the larger screens,this could be at fault even though it looks ok,try shinning a light on the screen and checking every inch,could be the internal screen that has damage hence why not powering up.
Failing that it sounds like an internal short.
