There is only the vol level ctrl in the menu

I had this problem on my Aquos (LC-46D62U). It was NOT a hardware problem. I recommend turning off the television. Next unplug the television for 5 to 10 seconds. This resets something for the television. Plug it back in and turn on the television. You should now be able to get your volume and other on-screen displays.

If you have satellite, I am assuming you at least have a converter box hooked up. If so, make sure the converter box volume is set at its max. There may even be a volume setting in the converter menu that forces the volume output of the box to always be at full so that you don't get variations in audio when changing channels. Warning...before attempting this, please turn down the volume on your tv to at least the middle setting so you don't blow your tv speakers if this works.

ok please open the remote then clean it with pencil eraser.

the TV needs to be reset with the Factory Initialization. Try contacting Sharp at 1-800-327-4277 for instructions.
