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.

Pressing i+ button (bottom left on the original remote) for 5+ seconds worked for me...

It sounds like you have a defective Main Control board. I would contact a service co. as soon as possible.

I had this same issue, and solved it by putting the TV in "Theater Mode', which can be acheived by hitting the "Theater" button on the remote.
