Question about Denon AVR-2106 Receiver

2 Answers

Power on problem

I was playing a cd at low to medium volume. Heard a slight pop and receiver kicked off to a flashing red light. I assumed that the speaker protection circuit was at work here. I unplugged the unit and checked all speaker connections. Upon powering up the unit. The led power button was flashing green then kicked off to a flashing red. I had disconnected all speakers from the unit. And it still kicks off to a flashing red. Any suggestions?

If your amp looks like it's going to work as normal (ie the front display lights up as it should etc), but then the amp goes into protection mode when the anti-thud circuit times out, then I know what's likely to be wrong.

It's one of the power amplifier channels which has gone faulty.

I just found this out after having this problem with my AVR-1906.

I took the amp apart and de-soldered the suspected channel power transistors (centre channel in my case).....and hey-presto! it fired up as normal (obviously the centre channel would be out of service).

I have ordered the replacement transistors from Farnell (UK) at a miserly cost of around £2-£3 each.

Just waiting for them to arrive.

An alternative is, if you don't use all your channels, take the transistors from a known working but not needed channel and swap them over with the duff ones.

Hope thats of use!

Time for a little repair here. It seems that one or more channels have developed an excessive drain on the supply, and has caused the threshold to trip and shut you down. It's more than likely shop time at this point....accordianman

Please check the power to the circuits, it is possible that the voltage to the preamp section is reduced and so there is low amplification. You will need to inject a AF- audio frequency - signal to trace the loss of amplification.

I have hk3385 receiver and Ipod Touch 4G. I have the cable to connect them. Where do I hook the cable on the receiver (or do I?) and which buttons will play the Ipod music. No video, just music


The manual suggests that you use "A / V 3" (audio / video input 3) for your iPad / iPod audio input. These are the RED and WHITE jacks on the front lower right hand side of the receiver. The YELLOW jack is for composite VIDEO, and need not be connected for "audio only" programs.

Turn the volume on the iPod / iPad to MINIMUM (assuming the receiver volume is at a "normal" setting for the radio, CD, etc.). Connect the cable between the iPod / iPad and the A / V 3 RED and WHITE audio jacks. Select A / V Input 3 on the receiver. Find a song you want to listen to and select PLAY in the iPod / iPad. Slowly adjust the volume on the iPod / iPad up to a comfortable level. If there is distorted sound, adjust he receiver and iPod / iPad volumes up and down as needed. Generally, neither should be set very low or very high.

You can download the owners manual here.

I hope this helps & good luck. Please rate my reply - thanks!

Since the receiver eventually works, the delay circuit is failing. This is a circuit that allows the power supply to settle down before kicking in the output relay. This prevents the "pop" that was sometimes heard on older units. This should be a simple and inexpensive repair probably requiring the replacement of a couple of small capacitors in that delay/protection circuit.

My AVR 2803 shuts down when volume is at medium or above.


too big a speaker load,unit sensors shut unit down when speaker impedance gets too low . and draws too much current at hi volume.A bad woofer or tweeter voice coil burned by sudden excess volume can cause this,also partially shorted speaker wires.

Audio won't play on DVD - but it will play for CDs


Hello, you can verify that your receiver is working or not. When you are playing a dvd unplug the audio RCA plugs (red and white) from the back of the Sony dvd player. Touch the tips of each of the RCA plugs with your fingertip. You will hear a buzz sound coming from the speaker associated with the plug if the receiver is working\ i.e. touch the red RCA plug tip and the right speaker will hum...touch the white tip and the left speaker will hum or buzz. This will not hurt your system or speaker. If you do not hear the hum turn the volume to 3 or so and wet your fingertip and tap the tip of the RCA connectors. You will hear "pops" coming from the respected channel. I believe your cd\dvd is at fault. Good Luck!

JVC RX558 VBK, Crackling noise from speakers


A quick quess of mine is the following:

The OVERLOAD indicator lights up when the receiver is maxing out on the current it is sending to the speakers. My guess is there is possibly something wrong with the receiver itself, especially since the B speakers won't play. Either that, or something is broken in your speakers or you are using a set of speakers that have too low an impedance rating for your receiver.
