No, you have to follow the procedures in the manual to inform the unit that there is a subwoofer, then select some parameters on how it is used depending on the functional sizes of your other speakers.

Just go on the menu and adjust levels of each channel . The menu has specific settings for its channels.

I have been trying to find a way to do this for over a year, Denon & DirecTV ay they are not compatable

First of all please check the mode in which you are operating. Use the tester to see if there is tone on the speakers. Use a good DTS source and swtich over to 5.1 to check for requrired levels. If there is no sound yet, please open the cover and check for the connections to the front channels, check if the relay is clicking. You will have to look into the output mosfets for damage. for this the main board has to be accessed. If you think that you are not able to go deeper into find out the nearest Denon service centre. many such centres do not accept a set if tampered and so you need to be careful not to make it more costly. Hope my advice helps. Good day

hello i believe your problem is that you are trying to downconvert from hdmi to component connections and Denon receivers will not do that.

I have a 4310 and I know it will UPconvert from an analog signal to HDMI but won't do it the other way around.

you may have to use component inputs for all your equipment. You will also have to go into the receivers menu and designate which signal is being used for each component as it won't auto select between analog and digital signals when it comes to video.

hope that helps

more info please...???

There is a problem in one of the output channels of the amplifier. That is the only reason it will do this. I work at an authorized Denon service center and have seen this problem several times, but it has never been the same thing that causes it. It has always resulted in extensive troubleshooting to find the problem. One time it was a capacitor in the pre-driver circuit for one of the channels, another time it was a transistor in the same type of circuit. I can not remember all the other causes. But without the proper tools and the knowledge of how to troubleshoot an amplifier circuit you will never figure it out.

Since this is an older model, more than 3 years old, it is no longer under warranty. They get a 2 year warranty from Denon. You can take it to any service center that works on stereo equipment and they should be able to fix it for a reasonable fee. Probable around $125 to $150 depending on their rates. It may seem like a lot, but it is much cheaper than buying a new one.

Since this is really the only option for you, unless you have the tools and knowledge, a FixYa! would be much appreciated and appropriate.

If you would like to troubleshoot it yourself, let me know, I have the service manual in PDF and can email it to you if you like and help you with troubleshooting it. But be aware, it is not an easy job.

All of the Denon recievers I have repaired (over 100) that shut down after a very short time are going into protect mode. The display lights up and after about 10 seconds the display goes out and the standby led blinks red.
I have found that they have one of 3 possible problems and they all require that the reciever be taken apart and fixed at component level. No way to tell what your problem is until it gets put on a bench and troubleshot.

Problem 1. This is the most common problem. One of the front channels shorts out. On the big heat sink the front channels are at each end. It is the front left channel (close to the display) This requires that the output transistors be replaced as well as some driver transistors and some resistors and a capacitor. Lots of work for a blown channel. Denon has put out a bullitin to upgrade the bias transistor and change a couple of resistors to help compensate for this failure. That channel overheats more than any other channel.

Problem 2. There is a resistor that is right next to the preamp board that opens up. It is a 10 ohm 1 watt resistor and when it opens, it causes the unit to go into protect.

Problem 3. The +12 volt regulator fails. It is in the power supply area on a smal heat sink right next to the -12 volt regulator. Generic part number is KIA7812 It also causes the unit to go into protect.

Most decent repair shops can fix these from about $120 up to about $200. Depending on which problem it is and how fast they are at finding the problem. Most charge labor by the hour.

Get some audio cables from radio shack or gamestop and use the regular audio jacks on the xbox to connect to your receiver.  Your video will be HD, but your audio won't.

You will need an adapter amp which converts the tiny tiny signal from a magnetic phono cartridge up to the line level that you need to feed into your AUX input jacks. They cost about $20 to $30 dollars and can be found at Radio Shack. Unless of course you have a phono input jack on the back of your Denon unit. Good luck.

You will have to disconnect the B speaker wires and disconnect the speakers and measure the wire with nothing on the wires as it sounds lkike you may have a pinched wire or shorted wire somewhere, or the B speakers one or both are bad. I am leaning towarods the shorted or pinched speaker wires. I say this because if there was an amp problem, it would happen on the A speakers too as the speaker A and B is nothing more then a switch to turn the desired speakers on and off. Good Luck

It has a blown channel, unless you are good at repairing them I suggest an authorized Denon service center. This Denon not only needs the shorted output transistors replaced, but a few resistors, a couple of driver transistors and a capacitor on the preamp board as well. alot of parts to be replaced. I have repaired about a hundred of these over the last few years and my shop charges about $200 for this repair, other shops should be about the same.

It is either the capacitor that is used to for memory or more likely the main CPU chip. If that is the problem you can just leave it plugged in and on or buy a new unit because that chip is expensive.

Hello, please check/replace the relais. If you need more info please advice. Arpi
