Sound cuts out on my Sharp Aquos 37" LCD TV

After turning my Sharp Aquos 37" LCD on for about 15 or 20 minutes, the sound cuts out completely & stays that way until I turn it off. I turn the TV off for about the same amount of time, 15 to 20 minutes & then turn it back on, only to have the sound cut out after about 15 to 20 minutes later again.

Your inverter/lamps are bad. Those are only available with the LCD panel as an Assembly, and that is worth more than the TV.

SOURCE: Cracked LCD Screen on Sharp Aquos LC37D43U 37-Inch 720p LCD HDTV

Most LCD's just went down in price by around 2-400 dollars. I would suggest buying a new one. The cracked screen might mean that the liquid will ooze out and get worse and worse as it ages. However, it may only have a crack and not get any worse than it is now. If you can live with it and it doesn't get worse, you can view it that way for another 10 years and be fine.

The fact that the LCDs are cheaper now and you only have a 37 inch, you might consider getting a larger one that you have had your eye on for a long time. (Note: even though I am a firm believer in LCD's over Plasma, plasmas are a few hundered dollars cheaper and if you know your children are prone to breaking things... it might be the way to go.)

Replacing the screen is possible, but more costly than the new T.V.

SOURCE: My 37" sharp aquos LCD TV sound shuts off

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.
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.

Try the main resets in the back by the a/v in and out jacks. If this does not work, call Sharp Customer Service 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.

Your lucky you got that out of it, this is a common problem with this unit, the solder that is used on the sound card doesn't like heat and melts. You can take the sound card out and clean with alcohol for a temp fix, but this is only a temp fix. Sound card cost approx. 340 bucks my fix was a sound surround system. sucks hey!

No picture -- white screen -- no sound


With no video and the the colored stripes, it sounds like the LVDS cable needs to be reconnected to the LCD control board or the control board itself is bad. If the unit is only 3-4 months old, it should be covered by warranty
