Pioneer receiver -no volume or volume display on screen. As if the function has disappeared. Knob still turns; just NO effect

Did the volume control get an impact? Could be internal damage to the digital control. Did it act up prior to this non-function, like volume went up on a down command or jump up or down when a slight turn was made? Thnose would reinforce a damaged volume control.

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.

" 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

I have a denon 1801 and the master volume goes to +60 which is all the way up and i cant seem to lower it, the knob turns and everything else works just fine

First solution would be to try and use the remote. If the remote is able to, the problem is in the knob. If the remote does not work, the problem resides in the volume board.

The problem resides in the circuitry that the knob is controlling. Unfortunately this knob has a full range of motion, which means that it is simply controlling a computer chip within the unit. (i have an 1801 as well). What has happened is that some component on the volume board has gone bad, which is resulting in your non functioning volume knob.

Unfortunately this is usually a job for a professional.

If you have standard electronics skills (soldering / disassemble / reassemble), you can open the case and find where the volume knob leads to. There should be a smaller board, and see if you can access it. Usually they are rather hard to get to, or to get free to actually see what is going on. The best solution would be to find a parts receiver, and swap boards. This shotgun approach changes everything. Otherwise, look for any damaged components on the board. Swap out any components that are damaged, or appear damaged with comparable replacements.

Volume not function.

You need to be a bit clearer on the exact nature of the issue.
Please include if the unit was working and suddenly stopped producing sound (ie - speaker output fuse blew) or if you relocated the unit, and after hooking it back up, you aren't getting any sound (ie - not hooked up right) or if the volume knob isn't changing the readout for the volume level (logic or knob broken) - and also include the make and model of WHAT the volume knob is attached to (ie - Yamaha receiver model X)

I have a sherwood s-7200 receiver. The power knob will not "click" to turn off the just stays on. The powe knob is also the volume control. All functions work as normal except the receiver will...

Known issue with these models. There's a plastic washer cam thing in the back of the switch that breaks. Since no new parts exist, you much make one to fix it. Or, just use a power strip to turn it on and off.

Volume knob quirks

if you know how to repair, then replace the volume control switch. it is a digital type/mechanical type of switch with silicone oil on it to prevent sudden turn of volume. if i were the repairman i can simply clean the contacts of the volume control and pour silicon oil again. but i really dont know in your area if they try to clean those.

Reciever display changing by itself

Sounds like a bad microcontroller. First check on the function selector knob if there is one and make sure it is not stuck - move or rotate it back and forth. Also, if the remote is nearby, try removing the batteries from it.
