Panasonic SA-XR70 receiver - Volume problem

[jdunbar1015]

I've had this receiver since they were first available 3 years ago. When I turn the volume up or down the display on the receiver goes in the opposite direction. For instance when I turn the volume up the display reads 60, 59, 58 etc. instead of 1, 2, 3 etc. The sound becomes slightly muted when it gets to 35. Then I have to power it off and on to get the full sound back.

I'm wondering if this is something that can be corrected or is it time to get a new receiver.

Thanks for you input and advice..
