Sounds like the remote or the receiver may be faulty. The speaker icon with the zero means simply that the volume is turned down to zero.
When you press remote buttons, do you see a flashing light on the screen at all? Can you use the buttons on the screen itself to try and adjust the volume? You'd need to try these things first, so we know how to help you further.
