Sharp LC-26D6U sound issues

In October I had the sound quit. I had the TV for 18 months. I took it to an authorized repair shop where they replaced the audio board...three days later, the sound quit again. I took it back to the shop, they "reseated" the connections, and it lasted a very short time, so back to the shop it went. This time they "replaced the insulation pad in the audio CRT". The TV worked one hour, now it has no picture, no sound, and the power light and OPC/DL indicator lights are blinking. What now?

    Same sound problem. Was able to restore sound a number of times by using the "reset" procedure outlined in the manual. But may have run out of luck thid last round on no sound. There is a audible click a few seconds after resetting.

    My Sharp Aquos 26" LC-26D6u LCD TV lost its sound less than 2 years old. Took it to a repair shop who stated it needs a whole new board--not just a sound board--at a cost of $380. I elected not to repair it!!! Very disappointed with Sharp and will never recommend it to anyone!!!

    I am having the same problem....one day sound just stopped working.  Have not brought to repair shop yet.  Any suggestions before I do?  I have tried reset and system reset with no luck....still no sound....

I am missing the 4 screws that secure my TV to the stand and needed to know what size screws to buy. The TV is a Sharp LC-26D6U (old TV). Any ideas? Thanks.


They probably are metric M8 but the length is critical. Too short won't hold and too long may interfere with circuitry underneath.

My Sharp LC-26D6U has lost Audio. How can I fix that?


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 partstore.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, also from partstore.com. 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 also refer to post # 373 at: avsforum.com/avs-vb/showthread.php?t=647174&page=13 for some ?pics? of the information detailed here. My knowledge of how to solve this issue came primarily from finding the research efforts of ?Aureius? on the AVS forums, and particularly from his taking the time to post the solution publicly so that others might save time, money, and aggravation. I'm just passing along the information. Thanks Andy! I also wanted to mention that a couple of other very pesky common problems with these series of Sharp TV's involving symptoms of random powering-off and/or powering-on, and 'function lock-ups' of various sorts are easily remedied through two firmware updates (Main CPU: PH1UU112, Monitor: MD1UA104). These are not available to end-users via the internet but it may be possible to get the files from an understanding factory-authorized repair tech. They are installed using an SD memory card (don't use the HC high capacity sort, use only those that are NOT HC) which is inserted into a special slot in the back of the machine. For those of the DIY persuasion, information about how to check whether your TV has old firmware in need of an upgrade is readily available through internet search.

Wats the part no.for the a/v card (sharp lc 26d6u) ? getting no sound.i think this is the problem..


You don't even have to worry about what the part number for this issue. Sharp is taking care of this for customers even if you are out of warranty due to a mistake on how they made the tv. All you have to do is call Sharp at 1-800-237-4277. It took my repair in NYC (MTZ electronics) shop 1 day to fix the issue. MTZ electronics even applied 2 firmware updates that all the D6U tv's need to avoid other known issues with the lcd in the future. These firmware updates are for the main cpu PH1UU112 and the monitor MD1UA104. I am so happy and am loyal to Sharp for their fantastic customer service. I also want to thank MTZ electronics for having the best customer service and being the best repair shop I have ever been to. Good luck everyone

No sound at all!


I agree with everything that they are saying.
Most tv companies under design the cooling needs of the flat panel TVs. I had to fix a few TVs this way that had similar problems. Mostly with the picture on TVs freezing up because of the poor cooling design for the motherboard processor. I would give their solution a try before replacing circuit boards.

Blinking power and OPC lights


If you have tried to reset the TV by unplugging it for 2 minutes and still have the same issue then it is time to bring the set to a repair shop.

Sharp Aquos LCD only shows analog


You will prob. have to order a new original remote.  It has the options on it to change from analog to digital.  I don't believe there are any options in the menu or buttons on the tv that switch between the two.
