The "Official" Denon AVR-2807 Thread - Page 137

post #4081 of 4105
If you haven't already, refer to the microprocessor reset procedure in the Owner's manual. If still no joy, the AVR likely has a couple defective amps. frown.gif
post #4082 of 4105

Reset the microprocessor several times… No change.

 

Is there any way to conclusively confirm the amps are dead (other than using the test tone function)?  I need some evidence to bring back to the seller.

post #4083 of 4105
I'd say the fact that they don't produce a test tone is conclusive enough evidence. Get your money back.
post #4084 of 4105

Thanks!

 

FYI, I connected the Surround speakers to the Back Surround output terminals, configured for 7.1, and get test tones from the Back Surround channels.  We'll see how the seller responds.  I'm bummed because I really wanted this AVR receiver and the price was great.  Now I know why.

post #4085 of 4105
Possibly, although also very possible the last time he used it the channels were working so don't necessarily go into it with the idea that he was trying to pull a fast one over you. Just be happy when he returns your money. smile.gif

Hi everyone,

 

I have a problem and am hoping for some help;

 

My 2807 has been dropping the picture for the last couple of days. Turn everything on, and after an hour or so, the picture drops out completely. TV (Sony XBR of the same vintage) indicates there is no signal. I still get sound to all 6 speakers, just no picture. At first it would drop for a few seconds, once every 15 minutes, with the drops gradually getting longer and more frequent the longer it was on. Seems to last about 30 seconds when it's at it's worst. The sound never falters, and the picture is just fine when it is there. 

 

I bypassed the Denon and put the HDMI into the cable box and no problems for the entire evening, so I'm thinking the Denon is where the problem lies.

 

The entire system environment (cable box, Denon, TV) is unchanged, and has been working flawlessly for the last several years.

 

 

Any thoughts, input or advice from you experts out there? As a greenhorn, I think the AVR might be going South on me? 

 

 

Thanks in advance

Before you start looking at hardware problems, the #1 culprit is likely to be the HDMI cable itself. HDMI is a finicky connection type, both in terms of the data connection (handshake) and the physical connector itself. It could be something as simple as the cable being loosely seated in the input slot, sometimes wiggling it or reseating it more firmly can mitigate the issue; or the cable itself could be damaged or defective.

First thing though, is it happening with ALL sources or just your cable box? If the problem is isolated to one specific source, then that narrows things down in terms of troubleshooting.

Batpig,

 

The problem only occurs when going through the AVR. There is only the one source, the cable box, and it works fine when going directly to the TV. When I took the HDMI cable out of the AVR, and plugged it into the cable box, everything worked fine for hours. 

 

I'll swap out the HDMI cable and go back through the Denon and see what happens.

 

 

Thanks,

I've got a 2807 at my father's place who I visited this week. He said a couple times he got "No Signal" on the screen when turning on the sat receiver, Denon 2807 and TV. What I found fixed the problem was turning on the receiver first then the TV and Sat box. Been fine since then.

Your problem is different though if you get dropouts 60 minutes into watching TV. Definitely check the HDMI cable. But if connecting the cable box to the TV fixes the problem leave it that way. Cable boxes can be very finicky.

afrogt,

 

But by doing that, I am forced to listen through the speakers on the TV, and that's not so nice....

No, not really, connect an optical cable or digital coax cable from your cable box to the receiver for audio. I'm sure your cable box has a optical or digital coax output. Some have both.


Cable boxes can output video and audio simultaneously from multiple outputs.
post #4092 of 4105

afrogt,

 

Good call, good call. I can do that if need be. 

 

I was just thinking the machine was going away on me, and thought I'd ask folks way smarter than me if that were the case. Or if this is normal behavior of a 7 year old Denon. Maybe someone has had this same problem and knows the fix. That type of thing.

 

Workarounds aren't fixes in my book. And if the AVR is gonna die, might as well be ready to replace it.

Hello guys,
I have a 2807 hooked up to a PS3 that I use for Blu Rays and for games....I know it has probably been discussed before. I have the PS3 hooked up via HDMI directly to my NEC Plasma. The only was I get sound is to turn the TV volume up with the TV remote. I can't get any volume through the 2807 even after I assign an Optical audio input to it. I have no clue what I am missing-PLEASE HELP all powerful gurus. smile.gif

post #4094 of 4105
Sounds like you need to adjust the PS3 audio settings to allow optical audio output instead of the default HDMI.

Out of curiosity why don't you connect the PS3 directly to the receiver and then out to the tv?
post #4095 of 4105
Figured it would be the best picture direct to the TV...but this audio issue is a pain in the a$$. I went into audio settings in the PS3 and didn't see an option for optical. Will look into that again...thx for the guidance.

I am having this exact same issue after buying a new Panasonic ST60 50" plasma, did you ever figure out how to get it to work with your Denon AVR 2807?

post #4097 of 4105

The 2807 will accept a pcm signal from your Blu-ray player, it will not accept the bitstream of True HD, but if you set your Sony player to pcm, then it will convert the TrueHD to pcm and you will be able to listen to it just fine on the 2807.

wOriWS

As for DTS MA, I don't believe the Sony player can send that bitstream so it will play the DTS core and send that to the 2807, which it will play just fine.

post #4098 of 4105
Ok guys I need some help please.
I got a new samsung 60 pn5500 and a blue ray player also and am trying to hook it up to my 2807. I do not have comcast yet so tried to hook just my blue ray player up.

I have the following

Hdmi from fr blue ray to Denon as hdmi 2 will have comcast as hdmi 1

I then have monitor out from Denon 2807 to hdmi 1 of tv.

I selected PCM in setup for DVD on 2807.

When I turn on everything I get no source on tv and the left side of the Denon keeps flashing PCM for a seconds or so and I get audio, however it doesn't stay on long. When I am in the middle of system setup, it does not flash and I get constant audio however I never get a picture?

Help me please

Matt
post #4099 of 4105
The PCM setting needs to be made on the Blu Ray player not on the 2807.
post #4100 of 4105
To add to that, are you referring to the "decode mode" setting under the input setup for the Denon? All the PCM setting does is force ONLY decoding of PCM signals, and blocks decoding of anything else. There is no reason to change this setting from the default "auto" and in fact this setting doesn't even exist anymore on more current models.

As JD notes the key is making sure he player is not sending bitstream hi Rez audio since ethe 2807 doesn't decode TrueHD or DTS HD. But I doubt that's the issue here as the player likely wouldn't even try to send it as the edid of the receiver will let it know it can't decode these formats.

I think there is some other issue going on. Does everything work ok with the comcast box on HDMI 1? If so try simply plugging the bdp into that input instead just to test.

Oppo DBP 83
Denon 2807

Hi,

Is it possible to have the Oppo decode the signal, pass the audio via analog, and have then have the Denon apply room correction?

Right now I use the 8 analog outs on the Oppo and select Ext. in on the Denon. In this set-up will the Denon apply room correction? I also have the Oppo an Denon connected via HDMI.

When watching movies I seem to get a much more enveloping sound when I select auto in and utilize the HDMI connection and have the Denon do the audio decoding. For hi-rez music the Oppo seems to provide a greater level of detail (analog out and ext. in), while the Denon is more veiled (HDMI out and auto in), However using the analog out and ext. in the speaker levels (center for example) are way off which leads me to believe room correction isn't being used.

Thanks,

Dan
post #4102 of 4105
No, on almost every receiver (not just Denon) the multich analog connections are never digitized. They effectively turn the receiver into an amplifier, and the external source is the processor. The only thing the receiver typically does is apply channel level adjustments. That means the source provides all processing including bass management, delays/distances, etc. The goal is to provide a "pure" path to the amp section for high quality external sources.

All processing in the receiver like room correction occurs in the digital domain, so the multich analog connections cannot benefit from that.
post #4103 of 4105
Thank your for your response.

Am I correct that the 2807 can't receive lossless audio through HDMI? So basically analog in (ext. in) is the only way to go when listening to SACD / DVD-A. I guess I'll have to go back to the Oppo and re-explore it's room treatment settings.

Would I have to step up to a 2313ci or newer to get lossless audio (DSD?) through HDMI? Is that why those receivers no longer have the multi-channel analog ins?

Sorry for all the questions.
post #4104 of 4105
No, you are not correct. The 2807 can't DECODE the lossless codecs itself, but it can absolutely receive high resolution lossless PCM streams over HDMI. When HD audio first came about with HD-DVD and Blu-ray, the idea was that the players themselves would decode the audio and simply output the unpacked lossless multich PCM streams to the processor. So as long as the player itself can decode, the 2807 can handle lossless audio.

I would try connecting the Oppo with HDMI and setting it to decode everything (Blu-ray and SACD) to multich PCM. Then you can apply digital processing (like room correction, bass management, etc) freely in the receiver.
post #4105 of 4105
I had my Oppo set to PCM for SACD but Bitstream for HDMI. So it must of been downmixing to DTS when I was using the HDMI connection.

After updating my room correction figures in the Oppo I still prefer the sound using the analog connections.

Thanks again for your help.
