No sound on Sharp LC-37D6U

I've seen posts elsewhere regarding this, I get a ''tick'' as it powers up and no sound. I found a LC-45D4OU but have no idea whether the sound board is a separate item or part of the main board. I'm hoping it will interchange. Has anyone here torn down a Sharp LCD TV? If so, where is the sound board?
Thanks, Jon.

    We had a guy come out and put a piece of tape between the wires and the board. He said "this was a problem they company was experiencing". It lasted about 6 weeks and now the sound is off again. As it was intermittent we may have let it go to long and the board was damaged. We have a call into the guy now for more info.

Please be aware that this a big problem on this unit. The insulator material used by sharp to between the IC's on the AV board both on top of the boards and underneath the the AV pcb is failing. This insulator is mounted to the IC and under the metal heat sinc. Remove the back and pull the AV Board out of the unit. Use zylene or alcohol and clean all of the grey insulator from between the pins on the ic and order the replacement insulators from Sharp. Most times this will correct the no sound problem. Sometimes this has also damaged the AV pcb and it will have to be replaced. The parts that should be replaced come in a kit with sharp part # PSPKIT663WHZZ. If the kit is not available the 2 parts needed are PSPAZA663WJKZ AND PRDARA216WJFW.

I had the same problem on my 37" Aquos. Sound went out about 8 months ago after 4 years. Technician said it was the Sound Power Supply. Total cost to fix was $440. $250 for the power supply and $170 for labor. Has worked fine ever since. When I asked for the old power supply he said he had to give it back as a trade in. I don't believe that so I don't really know if the power supply was the real cause.
Now I've lost sound on 4 channels on my 20" Aquos. Great picture, but wouldn't buy another Sharp product.

Have you tried the reset buttons on the back of the TV?
It should be right below your Cable IN port.

If that doesn't work, you may have to take it into a repair shop for the main unit board to be replaced. The part # is KD352
It's $99.59 at Shopjimmy.com
So, don't let the repairman rip you off.

Our sharp LC-37D6U does not turn on. The opc/dl light keeps flashing green X3 then every second or so. and the blue power button flashes also. What might we have to do to solve the problem? thank you


The main tv Tuner signal board it is dead or it have problems,but tv still usable.Tries push the remote power switch off/on again everytimes OPC/Power LEDS lights flashes.Have to do this maybe 3 or 4 times for the tv to have a lite up LCD screen panel backlight to make the tv Tuner signal board to work again,for the tv to work.If still have same problems after 3 or 4 times power switch pushes off/on still have OPC/Power LEDS lights flashes.Mean the main tv Tuner signal board it is dead and can not be trying to save it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish tv Tuner signal board for the replacement.This solution 100% will work,if ur tv main Tuner signal board still have life left in it.I do this every few days out of a week for my 46" Sharp Aquo LCD tv set,tv it work all the times.

I need some information on buying a ac adapter or power cord for the Sharp Aquos Model LC-22SV2U.


Cord: http://www.newremotecontrol.com/catalog/dyn_accy_data.php?catnum=QACCD3097CEPA
Adapter: http://www.newremotecontrol.com/catalog/dyn_accy_data.php?catnum=UADP-0243CEPZ
On the adapter: I've seen them a LOT less expensive just recently. Google it and choose "shopping" to narrow results. There won't be many, but I think you'll find one at better price in just a few minutes. Try ebay as well; that's where I found repair parts for the same model. Good luck!

Sharp LC 37 D6U


When you turn the tv on, do you hear a faint “pop” noise from the speaker? If so, the problem is with the heat sink under the audio IC. Over time, the heat sink will lose its consistency and start to melt, thus shorting out the audio circuit. To fix, you’d need to clean off the melted residue on both sides of the audio IC as well as replacing the heat sink with a newly redesigned Sharp Heat Insulation Pad. It’s a pretty complicated fix, I suggest calling your local authorized sharp service center to fix this problem. The part is inexpensive, so you’re most likely looking at a labor charge (maybe around $200ish) for the repair if they are not marking up the price too much.
