I had this problem with my Charter and the box had a sound button on the actual box, not the remotes. Now I have switched to Direct TV Box and have found while not so low I can't hear it, it is much lower than I know it can be and have to turn it up in the higher numbers or turn on the surround sound to hear it. Anyone know what to do with Direct Box, Direct didn't know.

This unit has a chronic problem with the insulator material used on the heat sink on the ic's on the AV Bd. The unit must be disassembled and the AV bd. removed. The insulation on especially IC 2502 breaks down and must be cleaned off of the bd. and the ic and new insulator part # PSPAZA663WJKZ must be ordered and used as the insulator pad. If you send me an email to missiontracetv@msn.com I can send you the copy of the Sharp technical bulletin LCDTV-194.

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 (rubbing alcohol works quite well). Despite what the images say,
YOU MUST REMOVE ALL BLACK RESIDUE FROM BOARD. IT WILL NOT WORK IF ALL THE RESIDUE IS NOT REMOVED.

I used your site to look up a problem awhile back and was helped by a guy who went by, Les Price (missiontracetv@msn.com).

I purchased a Sharp LC-26D4U LCD television and after about 16 month, the sound went on the TV. I could not get anything but popping noises out of the speakers. I hooked the TV up to a stereo and the sound worked only while using the stereo speaker from the stereo, still nothing from the TV speakers.
I searched this problem on your web site and saw a posting in which this Les Price (missiontracetv@msn.com) posted a fix. He stated this unit had a chronic problem with the insulator material used on the heat sink on the ic’s on the AV bd. He stated the unit had to be disassembled and the av bd removed. He stated the insulation on the ic 2502 breaks down and must be cleaned off and that a new insulator, part # PSPAZA663WJKZ must be ordered and used as the insulator pad. He stated there was a Sharp Technical bulletin LCDTV-194, which explained the problem and suggested this fix.
I Goggled the suggested part #, PSPAZA663WJKZ finding and ordering the part from www.electronics-storefront.com. I got a copy of the service bulletin, which had pictures and instructions on the repair.
On 25-Jan-09, I disassembled the TV, removing the back, a metal mount under the plastic back, and three circuit boards, locating the heat sink on the back of the AV board. I left the black sticky residue on the heat sink as the service bulletin suggested and installed the new insulator pad as shown on the service bulletin. I put the TV back together and found the TV volume to work again. I could not believe it worked.
Taking the TV apart made me a little nervous. I am not a repairman, however I do like to, “Tinker” with stuff. There were a lot of screws and wires to keep track of and a little tricky to put back together. If I had to do it again, I would either video tape the disassembly to make sure I replaced everything back the way it was, or at least take a few photos while disassembling.
I just wanted to say thanks for your web site and thanks to Les Price for his help. You both saved me some cash.

I have the same problem with the TV occasionally turning itself on but it only happens once in awhile. Still have not found out why this happens.

Hello
If your Roku 3 player is not connecting to WiFi, it is possible that the WiFi signal from the router is out of range. In order to strengthen the signal, move the router and Roku 3 so that there are fewer objects and walls between them.
