Mr Paul.. Thanks ur valuable information . I got a unit and it had one power transistor gone. even after replace not work but I follow ur instruction done. Appriciate.

Because in order to use a digital input, the unit would have to completely power on. Zone 2 is designed so that it can be used with the main power off.

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

ok my denon avr 1804 was jamming and it shut off on standby red light flashing comes on then goes back off what is wrong ?????

You need to get the manual and do some reading first. I couldn't find the AVR-1804 but the AVR-1803 is avaiable. It should be close enough to get you through connection and setup.

Disconnect all speaker wires on back and then turn on. If it happens again, it's most likely a power supply problem. If it doesn't happen again, it was probably crossed speaker wires.

Did you try to reset the unit? Resetting the unit has fixed every problem I have ever had......turn off unit.....hold down A+B at the same time then turn the unit back on...hold buttons for roughly 3 seconds....Let me know if it works.

First make sure you you have the power plug plugged into the unit and a hot 110 outlet, press the on/standby button on the front of the unit and if no power return to store
