Denon AVR-987 System setup lockout

I connected by Roku to a Denon 1804 Receiver this way:- I plugged the cable that came with the Roku into VCR2 input jack of the Denon. (I used VCR2 because it was available).- Using the remote from the Denon, I made sure the slide switch was on "Audio." (See page 20 of Denon Manual).- I pressed pressed the System Setup button- *System Setup appears in display of Denon- Using the cursor buttons I scrolled to menu Digital in Assignment- I set Menu item 16 Coaxial to VCR2 since that was the input jack I used for the Roku. - After making the selection press the CH Select Enter button to save- To exit the System Setup press the System Setup button again- When using the Roku, select the input source as VCR2 (or whatever jack you used). You should now have sound through the Denon.The most important step is to read the Denon manual starting on page 20

Did someone turn the OSD off on the menu? You might try a reset of the receiver. This would be in your manual.

There's no user parameter for "no sound during Test Tones" so a reset would be futile.

Carefully examine the front panel for clues like a misplaced Mute, Tape control or Multichannel Analog (EXT) Input selected.

Hi,

First make sure that your remote control is set to "Amp" as it can control many different devices.

Then make sure that you have connected the Monitor Out socket on the receiver to your TV.

Next make sure your TV is set to show the picture from the input you connected to the Denon monitor out.

Now press set-up button on the remote and the System Setup menu should appear on your TV.

If this helps then please rate my answer,

Many thanks,

Chris

Get into System Setup and run through the Speaker Configuration routine. My bet is it thinks you don't have Surround Back speakers.

Open the door on your remote. Select "system" button...then hit "next" button to scroll through setup features. It will be option number 10. Use the up/down arrows underneath the "next" button...this will allow you to assign the optical input to a particular input, e.g. DVD player. then just touch the "system" button again. You should be set.

Are you connected with video cables to a tv or "monitor" this is more than likely were the setup is visible for speaker configuration, input assignment etc, most denon receivers work this way so I would suspect you need to re-check the video connection until a set-up picture appears.

Make sure the S-video and the composite cable are not plugged in it the same time from the Denon of at the Plasma

check the following1-no headphone jack is inserted.
2-check power cord firmly connected.3-if you have any doubt in remote change the battery with fresh new one4-unplug the system from power and replug it.5-check your volume level maybe it is in low level.-setup your speaker again.6-check speaker cables disconnection-7 -check that mute button not pressed.

its related to the control AVI switch inside on the right side with the contact and 7 Ri sisters.
about 200.00 something to repair.
I can help with some money do you have the reciever still???
