IMPORTANT UPDATE:

As of January 25th, 2011, it has become apparent to the majority of the user base on AVS that Denon has addressed and remedied BOTH the "Blue Rain" and "Audio Loss" "bugs", via a pair of firmware updates to the unit.

So long as properly updated, NO 4311's should suffer from either.

Please ensure your unit has the most recent firmware. You can do this by connecting the unit to the internet via an ethernet connection and checking for a "firmware update" within the on-screen menu, found within "network settings".

See the official 4311/100 thread for further discussion regarding the units:

http://www.avsforum.com/avs-vb/showthread.php?t=1274153

James

This poll is purely an effort to get a handle on just how wide-spread the video-related "blue-rain" and audio loss (not to be confused with temporary audio drop-outs which are not terribly uncommon amongst Denon ((and other)) AVR's...especially with cable and SAT receivers) troubles are, as well as provide a clearing-house for information specific to either of these unfotunate phenomenon with this otherwise excellent AVR.

I invite me fellow AVSer's (especially those actually experiencing either condition) to supply those unsure of the make-up of either with a helpful, brief, testimony if they're so inclined.

In an effort to narrow the scope as best we can, it would also be helpful to include the following: serial number of your 4311/100, display model, methodology of connection, source components (and whether they are specifically effected), etc.

Perhaps a baseline of when, where, and how these bad guys are occurring will yield some assistance in finding a solution.


thanks,
James

Audio-loss on Dolby Digital 2.0 (stereo) audio streams that show up as having "embedded" surround - FL/FR/S input indicators are lit. Happens with Audyssey on and off and a surround mode enabled (observed with PLIIz, PLIIx and Neo:6).

Via HDMI and SPDIF (coax). Audio is lost, but can be restored by switching Audi Input (e.g. from Auto to HDMI) or chaning surround mode (e.g. from Dolby PLIIz to NEO:6).

EDIT: I also have UI/OSD disappearance that gets restored after switching to another input and back. That seems to be HDMI handshake related.

I do not have the blue rain or audio loss issues.

Some how I was thinking the poll would have been all over the place, and folks screaming and b**ching about how Denon had ship out faulty AVR's I guess it's still early, and perhaps 4311ci and A100 owners haven't have the chance on seeing the thread yet.

^ just for that reason I suppose this is a bump as well as an acknowledgment that there MAY be another video issue (I use the word MAY very cautiously) that's alluded to in the official thread, but until we/I see considerable replication of it, I do not feel comfortable adding it to the poll. And since there's prolly a reasonable chance it's related to "blue-rain" (read: a faulty HDMI board or video chip), its inclusion could prove to be a bit redundant anyway.

Thanks,
James

My A100 (Ser # 0101500096) hasn't had blue rain, video or audio issues after 5 days of testing. Video convert and IP Scaling has been running fine so far.

The first weekend I used it, I could see the blue rain when playing very dark scenes on BD or DVD from an Oppo BD 83se to a Benq5000 projector. Since then I turned off video processing and have not seen the issue again. I assume it is still there if I turn on the video processing.

It is not really an issue for me since I do not want the video processing but I do believe it is a bug that needs to be addressed.

Blue rain seems to be a hardware issue, which seem to be confirmed by at least one case of A100 being serviced where new video board was ordered as a fix.

Turning off "video processing" also means not getting OSD overlay such as volume/surround mode. I would not give up on that.

I'd suggest you exchange your unit.

But did it actually fix it?

Often the first attempt is replacing h/w, which is easier than actually diagnosing what the problem is.

I'd suggest you exchange your unit.

Exchange the unit is not an option here after 7 days of purchase, you are left to deal with the service center.

Though maybe I am missing something, if I change to "game mode" does it not stop the video processing? That is what I did and I haven't seen any blue rain though I am able to get the volume overlay on my display.

Maybe I have to go back and check how I have it set but I am not getting any now. As it does now seem to be an actual hardware issue, I will wait to see if they are able to fix it for others first and then schedule a warranty repair with the service center.

Hey gang: if you'd be so kind, how about including your build date and serial number? Perhaps we can then surmise if this was a first/second run issue.

I'm kinda getting this feeling it may be as an unoffcial count of mine has 5-0 of October builds with no problems. Certainly not for sure at this point though (especially considering most are NOT posting their build dates), hence the asking for the inclusion of build dates with replies from here on out.

thanks,
James

It is hard to deal with those type of issues because generally speaking, when we pay good money for a receiver we want it to work out of the box

A couple of questions. Is this blue rain only happening when using a particular type of connection? Meaning is it when you are using HDMI or composite or on all sources? I'm going with the assumption, since you are an experienced AVer, you made sure cables aren't causing any issues. Also have you tried disabling the receiver's video processor to see if that is the culprit? Basically I'm trying to find out if the receiver, the cables, or the video source is the one not playing nice.

Precisely what we're attempting to discern here.

One 100 owner has already been told he has a faulty HDMI board and his problems seemed quite aligned with others.

And although your interconnects point is taken, it stands to reason that there wouldn't be this volume of users all having issues with interconnests that were working just fine literally days ago with other units.

I invite you to check out the official thread for more intimate detail as to the specific situational criteria of users having this problem.


Keep those build dates coming people.

No problems at all with my A100.

S/N 0091500377

edit: I should also add that my source and TV are both less than 6 months old, so maybe I have less chance of other issues????

Sounds like bad boards. Yuck. When people post build dates maybe you can determine that they had a bad batch.

BTW: as I posted in the official thread:

A rather reliable little bird has told me the delays of new 4311's are "related to engineering upgrades".

Please trust that this source is solid, I'd rather not disclose his identity.

And: whether these "upgrades" have been ongoing, I do not know. My suspicion is that they have, judging by the uptick in newer units being seeminlgy less prone to the problems.


all the best,
James

Just received my 4311CI on Friday (11/12/2010) and spend all the next day setting up. No rain nor audio dropouts detected testing all sources.
Hookups into 4311CI via HDMI:
HD Comcast Cable Box
Sharp Bluray player
Panasonic DVD recorder
Output:
One HDMI to Sharp LC-52LE810UN via ARC input
Ran Audyssey and kept recommeded settings; left video settings on default.
Played Avatar in Bluray and Ironman 2 in DVD with no rain, no artifacts, no nothing other than great PQ in both formats. Audio quality far better than Yamaha RV-X2500 it replaced.

No date of manufacture on back of unit, only Serial Number.

The build date appears to be incorporated w/in the serial number, e.g. "0915" and "1015," meaning September and October, respectively.

(To clarify, "15" probably indicates the 15th day of the month, as build dates in the past have been pegged to that day.)

I mean where each potential issues is written up on the poll, usually the member who has voted the name pops up. I would like to know who is voting , but come to think of it it might not be not be such a good idea..It might shy folks away, who first claimed they had some sort of problem only to find out it was user error.

I voted problem-free for my September (09) 4311 but I do have rare (three times so far) instances of audio loss or (the last time) 5.1/7.1 confusion. The video problem is so extreme as to have to be a hardware fault but I think the audio issues are more subtle and are mostly due to software defects in the Denon HDMI system.

I fired up my first BD and I have white rain on black (maybe because I turned the Screensaver off?).

In the first scenes with a lot of black, vertical white streaking.

I switched to Game mode and it fixed it.

009150

JVC XVBP1 BD player
JVC RS10 projector

both connected via HDMI

No audio loss yet, but that's just after one movie and a couple of hours of analog audio.

Do we know if Denon is monitoring this thread, or should we be calling them; anyone have the number handy?
