My denon AVR 1913 will not connect to the internet/network as set up connected to the router. there was no problem with this one week ago, but following a power outage last night, i cannot connect to the internet. the router and internet (comcast) are fine, as i'm on the notebook via wireless connection right now. i've already swapped out the ethernet cords to verify there isn't a problem with the cords, and adjust the connections as well. i have rebooted the entire system including the modem and router three time, and still no connection detected. there is a green light on the router that lights up when a connection exists, the other cord from the router (to the samsung tv) is lit green. i switched ports on the router to make sure, and the tv still had internet connection. any other ideas i may try?

I mwas gonna suggest that you need the speakers attached but you stated later that it did the same thing with the speakers attached. The unit switching off after it checks its self is NOT a normal thing. TAKE IT BACK BEFORE ITS TOO LATE!! GOOD lUCK

I have repaired many of these Denon receivers over the last few years.

Since the headphones work, that means if you dis-connect the speakers it will turn on and not go into protect (when power cuts off a few seconds after turning the unit on).

The most likely problem is a bad speaker. to find out which speaker is causing the problem, do this.

Start out with just one speaker connected and then turn on the unit. If it turns on and plays music, you know that speaker is good.
Now turn the unit off again and add another speaker and keep the first speaker connected. Once again, if the unit plays, that speaker is also good.

Keep doing this same procedure one speaker at a time. As soon as you connect a speaker and then try to turn on the unit and it goes into protect, the speaker you just connected is bad.

To confirm that this speaker is the bad speaker, dis-connect all speakers and only plug the suspected bad speaker into a speaker jack that worked with one of the other speakers.
If the unit still goes into protect you know then that you have found the bad speaker.

If the unit still goes into protect, that speaker is bad and you will need to take it in for repair or replace it.
make sure you use 8 ohm speakers. if i remember correctly these Denons can use 6 ohm speakers, but those are harder to find and most home speakers are 8 ohms.

If the unit does not go into protect and that suspected bad speaker plays in one of the other speaker jacks, what you really have is a bad channel in the amplifier, the channel that the suspected bad speaker was previously connected to.

If you find out you have a bad channel, you will need to take it in to an repair center. Preferably an authorized Denon service center. There are not very many of those around. I work at the only authorized Denon service center in the entire state of Michigan.

If I can be of more assistance, don't hesitate to ask. And a good rating is always appreciated. :)

The connection order can be a key issue as to whether or not the HDMI signals will pass through the system. For best results the receiver should be turned on first, then the source device(s) and then the display. The reason for this has to do with getting the equipment to handshake properly for the HDCP protocol.

If HDMI video will not pass through your receiver, you may with to just connect the xbox using the component cables. Since component will pass through 720p and your TV is 1080i you should expect the same qualtiy and a more crisp picture.

I like when a user is observant and curious. That will help immensely in resolving this problem.

What source(s) are always involved with the problem?

You imply it is observable with output video to the TV - "only when there is movement on my tv screen and it stops in still screen". That sounds like a digital pathway problem of some sort as any data errors would eventually escalate to something audible or visible to you once the hardware and correction algorhythms are exhausted. The clicking inside the receiver could be its efforts to resynchronize with a bad data stream. Hence, I'd like you to isolate the ins and outs that fail all the time and find the probable single source of the problem.

Try this: put a digital source on and select/deselect it for listening or viewing. Does it make the click in that brief time it's 'thinking' before you hear the source? That would be the 'normal' sound. My Pioneer does it once per source switch. Repeated clicking would mean it's struggling.

I'm betting you have an optical or hdmi cable that's flaky or not in tight and straight. Or, if only one extternal source is involved we follow that back.
