Sharp LC-37D6U Aquos audio problem

Check the audio 'output select' under the Systems Settings menus. The output may be set to 'variable'. Set it to 'fixed' so that the audio runs through the speakers.

Do you get sound when hooking tv to a receiver with speakers? If so it could be a connetion problem or the sound board is going.

Actually there is a service bulletin on this television. Sharp will repair the no sound problem for no charge. Call 800-237-4277. Please remember to provide feedback here if this helps you.

Sounds like an impact to the screen. Screens can't be fixed.

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.

hi
i have the same problem with my 37 in sharp aquos it has a broken screen. i have done alittle research and you have to open it up an find make /model and number of the screen before you can get a quote to fix or before you are able to get a screen
try that and then see what you get on googleing it

the goop under the heat sink is thermal compound and some of it is toxic so please be careful.

there many lesson for u are problem, try to change the cable in audio in,if doesnt work try to see expers near you.

I'll tell you but it's not easy to do it. The heat sink radiator for the audio amplifier IC is touching the circuit board. You have to remove it and to replace the sillicon. The radiator is situated on the back of the AV board. You got to remove all boards to get this one.
Good luck.

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.
