Denon Audio Players & Recorders - Recent Questions, Troubleshooting & Support


I had the same problem with my subwoofer unit. I found the zener diode ZD3 was fried. The pic below shows the diode and its clearly tagged ZD3. You need a multimeter to check this before you order anything. This diode should only transmit power in one direction. Its size and spec is 18v .5w zener diode. (that's 1/2 w) It's very inexpensive and the whole repair took about an hour. This is from a Boston Acoustics subwoofer MCS 160
Ok..the procedure is easy.
1) unplug the unit and bring it to a well lit work area.
2) remove the panel from the back and locate the board that is held to the panel by 4 screws and has the ZD3 diode. The pic below shows the diode at the end of my test lead. Note the direction of this part and reinstall the new one in the same direction. Its a simple de-solder and re-solder project. I elevated the new diode about 1/8 " from the board with a small strip of copper. This acted as a heat sink during the soldering and elevated the part above the board to help it dissipate heat later when in use.
3) re-install the board and plug in all the connections.
4) this worked for me and I'm enjoying my sound system again!..good luck0482b949-8492-43a6-91df-0fb2f0e6888b.jpg

This will depend on the Blue ray player and other equipment. For a direct connection to the receiver, if your player has either type of digital audio output (coaxial or optical), get the appropriate cables. Then connect the chosen cable between the Blue ray player and the receiver. Connect the Blue ray player to the TV with an HDMI cable. See page 10 of the manual, available at http://pdfstream.manualsonline.com/6/69f43064-f593-49b8-8d4a-23174b496e65.pdf , to see the connections for the audio sources. (I'll assume your Blue ray player doesn't have component video out or you would use the component audio to the receiver.)

If your player doesn't have a digital audio output, check your TV audio output. You can get the same result by sending the videos via HDMI to the TV and using the TV audio out to the receiver. Set the audio source to TV and leave it there for both TV and Blue ray and DVD videos. (Sometimes there could be a slight delay in the audio compared with the video signal when you do this. I've never noticed it with my Blue ray player signal going to the TV and the TV digital audio out to the Denon receiver.)

If you can't send the audio out to the receiver from either your Blue ray player or TV, then you will need some sort of HDMI audio extractor. You can find models with Analog Audio Out, Digital Audio Out or both. ( https://www.amazon.com/J-Tech-Digital-Extractor-Converter-JTDAT5CH/dp/B00BIQER0E lists units with both types of audio output. One models requires a 3.5 mm to RCA audio adapter.)

I hope this helps.

If DIGITAL sign blink, this mean DSP board is defective. It will cut the sound on the AMP section. DSp is maybe defective.

After you have set your clock time simply just hold down memo button and I goes to minutes and click memo once to save your chosen time.

I expect your tuner/amp has a fair number of ultra sensitive CMOS devices inside and a power surge is likely to be instant ***** for them - if the surge reached them.

Any piece of equipment that has a computer inside really should be protected by an anti-surge device.

Your Denon tuner/amp is a bit of really premium equipment and I advise you it is best to entrust it's resurrection to a Denon approved repairer.

DTS (digital theater systems) is the name for a company that has it's own proprietary digital encoding for the audio, just as Dolby Digital does. In order for your media to have audio output in DTS, it actually has to be encoded with the DTS software format, AND manually selected by the user to play in that format. Incredible Hulk is NOT encoded in DTS. Select a movie that has the DTS encoding by checking the rear label of the case on the format table.

if you want to set your playback speed exactly right, you need a test tape with a test tone on it (3khz for example). now you hook a frequency counter to your tapedecks output and set the speed accordingly.
