SOURCE: Sharp TV Audio Problem

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 HDTV LC52D62U Caption Not Readable


Try doing the Factory Initialization (WARNING: THIS GIVES YOU ACCESS TO THE SERVICE MENU. DO NOT ADJUST ANYTHING IN THE SERVICE MENU OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS. IF YOU DECIDED TO ADJUST ANYTHING OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS, I WILL NOT BE RESPONSIBLE IF ANYTHING WRONG HAPPENS TO YOUR TV.)

  1. unplug tv
  2. press and hold at the same time “Vol –“ and “input” button on the TV set.
  3. while holding those buttons, plug the tv back in
  4. the tv should turn on by itself, keep holding the buttons until the letter “K” appears. Then let go
  5. then at the same time press “Vol –“ and “Ch. Down”, you should see the service menu appear (if it does not appear, try pressing the two buttons again, it needs to be exactly at the same time)
  6. Then use the “Ch. Down” button to navigate down the service menu until you see “Industry Init” (NOT Industry Init +cause)
  7. Then press “Vol +” to toggle it to “ON”
  8. Then “/////////////////” should appear.
  9. when the screen turns GREEN, unplug the TV. Wait about 30 seconds, then plug the TV back in.
  10. Then continue on with the initial setup again.

This puts the TV back into the “fresh out of the box” settings. See if this helps with your CC problem.

Sharp TV switches to "input 2"


There's an option on the menu to tuen 'demo mode' on and off. If it's set to on, that's your problem. It will be switching input sources every 2 minutes or so. Switch this off and it'll be ok again.
