Do you mean that you can't adjust the volume manually from the front panel knob as well as the remote?
Are you getting any volume at all? If so the problem isn't the volume control but something else in the receiver.
Do all your sources not produce sound? Try the built in radio.
that's correct, the volume knob on the front panel doesn't work no more, but i've found another remote control which do work, so luckily i have the volume back right now.. the volume knob doesn't work manually still though..
