Hi
Sounds to me like you may have a cold solder joint in a board ( loose lead on the pc board ) or you might have a b ad eeprom causing the problem. You may need to replace the main board. Also another sitution I have come across is a stuck button on the tuning strip board ( the board/switches that change channels, volume etc ) on the tv. maybe also since the remote sensor is light senative, it may be in the line of the sun ( cover the ir senor on the front of the tv to illaminate that problem ). Good Luck and if you want me to ask anything .contact me
Well, you need to check the capacitator in the sound part or the audio out panel. I think it requires an authorised doctor to look at it.
Also, it is a software problem of the volume getting stuck. If there was a problem with the parts, it would have been that the sound gets stuck at the level and the TV should have shown an increase.
Have the capacitators checked. It may have got swollen. If it has, you need to replace them immediately. Also, it may be dangerous if you don't do it.
If you still have the warranty, contact the manufacturer about the faulty parts that you find. It will be replaced free of cost if you haven't done anything on it that caused it.
Jus unplug it, took the back off, use compressed air to clean the dust and dirt out of it. check the soldiering joints and give it a quick look. Wthen plugged it back in and the sound may work. when it was unplugged, it reset itself and is good to go.
when u have problems, this will be the first thing that u do; to unplug and try to reset it.
I had similar problems. Actually two incidents...
One time it was the board in the back of the TV that had become useless. The other time it was one of the smaller capacitors that got fried...
I simply replaced those dead parts and everything was back to normal...Luckily I had same TV whose monitor did not work, so I swapped the parts from that one...
Anyway, since that was in a hotel industry, it can be a little different at home.
You might as well get a new TV. If you plan to give it to the repair shop, where they usually overcharge... The new ones support more peripheral devices and are better quality overall, especially LCDs.

The sound problem is likely not related. Possibly some leaky caps in the
audio circuit. It s better u consult any service center...
Are you using a remote or changing it manually.

It does not matter if I use the remote or the buttons on the set the behavior is the same. There is a sound level meter that will come on the screen and move up and down as I adjust the volume but the sound is not coming on as it should.
Also when I turn off the TV sometimes I will hear a loud popping staticky noise. I did check for any loose connections months ago and did not find any.
