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.

Sharp LC-37d6u audio problem


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.

Sharp LC-37D6U Aquos audio problem


Your Aquos does not have a separate Audio board, audio circuits are mainly on main pcb. If the guy was able to fix the problem by hooking a surround to the audio out, that means that is a problem with speakers contacts or with one of the outputs.
Borrow a surround or use an amplified speakers set and check if you can fix it with this trick.
To do a real fix, a technician must open the tv, and test all audio connection, and onboard connection to audio outputs to see what is wrong.
If TV is going to work with a surround you will probably get a far better audio quality than the one you get now from TV speakers.

Lc-37d6u intermittant audio issue


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.

Unpredictable audio output for no apparent reason


That click sound when the tv turns off is normal, that is just the relay from the power supply shutting off.

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.
