When I try to turn up/down the volume from the remote the knob on the reciever does not move. I can hear the motor trying to compute the command of the volume. All other functions work on the receiver

Remove the volume knob by pulling it straight out off of it's shaft. Use a dry cloth to clean off any visible crud and dust. Spray silicone lightly; the shaft and the shaft washer. Replace knob by aligning it by it's shape and work the silicone into the volume mechanism by twisting the knob a few time. Now try it with the remote.

I've got a vsx-920-k Pioneer receiver with s-11 Pioneer speakers and a s-21w Pioneer subwoofer. All of a sudden my sub stopped working and it seems like it's stuck in standby mode (blue light...

The manual is here...

Flashing Blue is not defined in the manual.

Have you tried changing the Auto Standby switch to ON?

You can prove if the sub amp will respond to a known good input by TURNING ITS VOLUME DOWN tp start and just feeding it ANY RCA output from the receiver while playing, say, FM (to keep it simple). That way you would known in which direction the problem actually lies (internal or external).

" display mode OFF"

You can select the display mode for the front display
of the SR7001.To select this mode, press the DISPLAY on the remote control or the front panel.When this button is pressed, the display mode is switched in the following sequence.Input Mode ? Surround Mode ? Auto display OFF ? Display OFF ? Normal Mode ? Input Mode Normal Mode: Displays the selected input function. If the function has been renamed using the Function Rename feature (see page 26), the renamed name appears on the display. Input Mode: Displays the input mode set via the Function Input Setup feature (see page 25). Surround Mode: Displays the status of the selected surround mode. Auto Display Off mode: The display is off. But, if you make a change to the unit such as the input or surround mode, the display will show that change, then go back to off after about 3 seconds. When changing the volume, it is not displayed. Display Off mode: The display is off completely. Note: • Only the DISP indicator will be illuminated on thefront display in display off condition

"The blue light around my volume dial does not light

Try resetting the receiver (you will lose your setup). I recently reset my receiver and the blue light returned. It's possible that the Audacity setup turns off the blue light because the volume is now being "regulated" by the equalizer.

Hi - You can download the manual by clicking the link underlined in blue below:

AVR 310

You're right this is a complicated beast to set up! I suggest you go through the manual & follow the setup guides there.

Possibly the unit has been muted via the remote control?
