There is a common problem with a zener diode in that amp that goes bad. ZD3 is a 18v zener and it goes short. Sometimes R9 on the back will open when this happens. Need to have them replaced.

    Steve, I've been trying to solve the same problem, i have a BA subwoofer on my Denon AVR 1312, fuse on subwoofer is good. Can you explain more about this ZD3 Zener diode - is this in the subwoofer, the receiver - what must I do to fix this?

  • Steve K Jan 09, 2016

    ZD3 is in the subwoofer. If it is shorted, it needs to be replaced.

The connection is similar to what is mentioned in the user manual bellow. Slightly different model but the connections are universally similar:

SOURCE: connect wii to Avr 1312 Denon

What you would have to do is connect the video output of the wii directly to the video input of the bug projector. Also connect the audio cables to it as well. Then connect an audio cable to the projector's audio out or otherwise labeled as "variable out" then connect the other end of that to the matching input terminal, found often labeled as "audio in" on the receiver's grouping of input selections for TV.
Then, on the projector, select the video mode you connected the wii cables to.

Check to make sure that when you are on that input that HDMI shows up in the front display. If it does not, then you need to turnit on. If it still does not, you could have a problem with your HDMI board on your receiver not recognising the signal.

My Denon 1312 AVR receiver doesn't switch on

Thist could be due to a short in the amplifier or in the power supply. You can try the following: disconnect all speakers and components. Then see if the unit powers up. If it does, turn it off, connect one item at a time until the unit fails to come on. That may identify the bad component.

However, it the unit never powers up when it is devoid of speakers and components, repair is going to be more tedious, possibly cost prohibitive. https://www.justanswer.com/home-theater-stereo/8uupb-hi-denon-avr-1312-receiver-just-stop-working-suddenly-check-chassi.html

Denon 1312 makes clicking sound will not turn on

If the front display does not light up at all when the press the power button, it is usually either the main power fuse or the power transformer. If the fuse is blowing, that usually means a short in the amp section.
