Question about Denon AVR-2106 Receiver

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?

Re: Power on problem

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!

Re: Power on problem

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

How do i get my speaker to work at high volume with out them cracking,popping destort

If you are using the factory installed speakers they aren't made for the wattage output of your receiver. Factory stereos only put out about 5 to 10 watts. If you want to play it really loud you need to replace them with speakers that have a higher wattage that what your receiver puts out, which is a maximum of 50 watts

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.

Power Button Flashing Red

Try unplugging the entire unit and letting it sit for 5 minutes. See if this helps. If not, you need to do a complete reboot, which will cause you to lose your settings, but will probably solve your problem. To do a complete reboot, you will need to hold down two of the front bottons on the front panel. I'm not sure which, so either consult your manual or see other posts here which describe the reboot process for Denons. Hope this helps.

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!

Denon DRA 395 flashing red power light

Needs to be reset or fuse blown. Take to repair shop, cover has to be taken off and fuse replaced. You could fix it yourself but the warranty won't be honored. Do it yourself electronic shop should have a replacement fuse, may have to be soldered in place. Repair shop, should cost around $30.00 to $45.00 to fix, price of fuse $4.00 to $6.00. Your choice.

I can help you solve this problem. However you must describe to me which fuse you have replaced. Is it the fuse on the power line or is it a fuse in the speaker line (which I highly doubt). usually this type of amplifier uses two technologies. One is transistors the second is integrated chips. This is in regard to the output stages. I assumed you speaker cables shorted each other while the volume was set at a high level with music playing. Anyway if you are willing I am able to help.

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.
