You may or may not remember that Denon tried to sell a special DenonLink cable for $500. Any piece of CAT6 Ethernet cable will work fine.
It is good to know that the DACs from the 3910 and 3805 do not sound very differently from each other. This encourages me certainly to use the DenonLink option.
An original DenonLink cable was included in my combo package deal (300 euro's), alternatively a cheap ethernet cable would do.

The DL3 is now connected to both the 3910 and 3805, in addition to the existing analog 5.1 cables. The initial setup has now become much easier indeed. First impression is a fine playback of SACD(-R) disks through DL3. I intend to do further comparisons between DL3 and analog playback of SACD for getting the best possible sound quality.
SACD is supposed to have inherently better sound quality by having for example a higher bitrate, frequency range and dynamics compared with the redbook CD. I favor the SACD over my CDs for better quality playback and concert hall atmosphere of classical music.
Last week I attended a concert with a performance of Bruckner's 4th symphony by a very large orchestra. Oh my, such a live concert can in my opinion hardly ever be reproduced in the living room by whatever equipment is available, to downplay a little our esoteric equipment discussions. Although the aim is and remains to approach it as close as possible.

Spot on, that was also my initial idea. I know, it is such a long time ago and I hesitate to ask, but would you still remember some, or have any notes, of those config settings?

Merry Christmas to all of you.

Which config settings do you mean? If you have been playing SACDs through the DL3 cable and you've run the RoomEQ calibration, you should be all set.

I am referring to the 3910 config settings for the analog 5.1 output that you preferred over the DL3 connection in your early post #6986 .

I wrote that post 10 years ago. With more listening time, I changed my mind and decided that I heard no difference between the analog outputs as compared to DL3.

In another thread on this forum I finally found the answer I was looking for.

In short it boils down to the following for the combination DVD3910 and AVR3805.


Analog 5.1 signals are handled and controlled (including speaker delay and levels) by the DVD3910, with the AVR3805’s only role accepting 5.1 analog input (via EXT. IN) and its amplification.

Digital 5.1 output/input control is in the domain of the AVR3805 including speaker delay and levels. DVD3910 for only CD readout and output via DL3.

I am going to setup both 3910 and 3805 according to the outline above and determine my preference, if any.

While you're at it, there are also a separate set of 2-channel analog outputs from the 3910 that are supposed to have some kind of advantage over the same channels played over the 5.1 analog outputs. You could put them into the comparison process if you ever play 2-channel music and don't use a subwoofer.

Hi All, greetings from Greece!

I own a DENON 3910 since 2005 although the last few years only used same for hearing music (CDs) with a DENON 3805 as I bought a Blu Ray player and a media player for watching movies.

For the last years when turned on the DENON 3910 CD player, while pushed button for the cd tray to open, at first it made a sound when opened (like something disturbed tray to open) but after all
the tray opened. After some time, when pushed button to open the tray although it tried to, after all remained closed and then loaded (empty). After a few tries tray opened, but now you need lots of tries and
even a small screwdriver or knife to assist open tray which should certainly not be the case.

Asked local official Denon Dealer what would be the cost (a) for fully replacing the tray mechanism (worst case scenario) and told me approx Euro 360,00 !!! (spare part+work included) which i think it is too much to pay for a very nice player which is now 13 years old though... Any idea if it is possible to find and order a brand new original tray mechanism, if required, and at what approx cost? I have found one in the web / Aliexpress / but really do not know whether this is an original one (costs 59,00$ )

Have also read some threads about cleaning the tray belt by using special rubber oil etc but i'm not the guy that filling confident to open on my own the player and start doing DYI things

Any assistance your side is most welcomed!

Many thanks in advance

Have you tried looking on eBay for a used 3910? When you're using it with a 3805, it does have the advantage of transmitting SACD audio digitally to the AVR, which later Denon players don't do.

Hello to all 3310 owners,

I recently exchanged a DENON DVD-3910 with a friend in excellent condition.

It plays back correctly every expected disc type, except for recordable DVD-A where the following odd thing happens.

While it normally starts to read the disc, navigate to menus, play all the conventional Audio Streams that are in various Menus/Extras,
when it comes to playback High Resolution MLP tracks, starts normally and in exactly 30 seconds goes to "STOP" mode.
It just stops playback by displaying "STOP" on the display.

Whenever I try again same thing happens, with different recordable discs, I tried DVD +R/-R single and double layer.
I've burned DVD-A Images with both Nero and ImgBurn, at the minimum speed of each disc.

On regular DVD-A discs this does not happen, playback is normal.

Also, thinking that the laser head is faulty due to weak power of laser, I replaced it ... but it didn't change anything.

Can anyone tell me if that rings a bell..?

Maybe a 3910 owner can try to playback a recordable DVD-A MLP Stream to see if it'll pass 30 secs playback..?

Thank you in advance guys.

You're likely bumping into digital watermarking. The DVD-3910 will stop at exactly 30 seconds into playback if the DVD-A you burned contains watermarked content (and not the other stuff necessary to authenticate the disc).

This is not happening when I playback the same discs on my DVD-2900...
Any solution - workaround for the 3910 ?

So, unsure if "michi" or anyone else is still around that cares about the laser pickups...

It's been quite a while since I packed my 3910 in a box awaiting the time to replace the pickup, as I too was having issues reading discs. After reading this thread, I had assumed it was the dreaded Fujitsu 1200R causing my issues. Well, low and behold, I finally pulled the pickup in preparation for fixing it myself and guess what, my DVD-3910, bought new and manufactured May 2005, has a 1200S. Obviously Fujitsu didn't correct their reliability issues between the R and S models...

Given that my setup was always in a clean (as it could be) rack with plenty of clean air circulating (no heat issues), I am surprised how these things passed QA at Denon. Now that Marantz is the high-end, I was also surprised to find that they used Fujitsu in their high-end models too. We will just have to hope things got fixed at some point along the way...

I am now waiting of the slow boat to deliver an 1120 and a 1200W-B. We shall see how long they last.

Hi. I know it's been several years, but which laser ended up being the correct one for the DENON DVD3930CI? Sanyo sfhd65/sf hd850? Need to know for immediate repair. Buy just the laser or the complete Traverse Mechanism?
Many thanks.

Exclamation DVD-3910 Firmware Version 8280-5

Does anyone have a copy of the 8280-5 firmware update file (D31ZSAVD.CFW) that they can post here?

I tried using the link posted on the DiyAudio forum, but the file throws a data error when trying to extract it.

The original file from Denon was GEN8280-5_918D_3rd_DVD3910.zip (1.10 MB) containing D31ZSAVD.CFW.

I just picked up a used DVD-3910 and the latest firmware I could find was 8280-1. Thanks!

I have this file but it is too large to post on this forum. Perhaps I could email it to you?

Hi Andre,

Thanks for the ZIP file, but looking at the 2005 dates shown on the individual files in the ZIP, it looks like version 6609-B or similar.

The 8280-# firmware updates are from 2007. The 8280-1 files I currently have are dated March 11 2007.

Boris - Sorry for the confusion. I was referencing the file name in your post, not the file version #.
I've rechecked my files and unfortunately do not have anything else I can offer. Again, I apologize.

I decided to make another attempt and after some file/directory manipulation, I was finally able to get the 8280-5 firmware version downloaded from the DiyAudio forum to unpack without errors.

Unfortunately after the upgrade, some of my SACDs wouldn't play, so I reverted back to the 8280-1 version and all is back to the way it was.

I thought I might be able to get a couple of my unplayable discs to work properly with the latest firmware version in the DVD-3910, but no such luck.

The blu-ray player I have plays them without issue, so all is OK.

Very odd that the later firmware version wouldn't pay SACDs reliably. I use the 3910 as part of a headphone system (bought the player new). I have the latest firmware. The only discs that haven't played are some CD-R discs that are black (can't recall the brand--other players haven't had trouble with them).

Hello,

I didn't do extensive testing. I was just trying to see if the newer firmware version 8280-5 would fix or improve my existing situation.

I have two discs that "won't play nice" in the DVD-3910 for some reason, Joy Division - Substance CD (player makes strange noises and doesn't recognize the disc) and Gershwin - American In Paris MFSL SACD (track 6 plays for awhile and then skips to track 7 or elsewhere later in the disc). Neither disc has any visible marks or blemishes. The playback situation for these 2 discs was the same with firmware version 6609-B and 8280-1, too.

With the newer firmware 8280-5, there was no change in behavior for the Substance CD and the MFSL SACD didn't get recognized at all, so I reverted back to the 8280-1 firmware version.

Both discs play normally in an Oppo UDP-203.

Can anyone tell me if the HOP-1200S can be replaced by the HOP-1000? I couldn't find a definitive answer.

EDIT: Just ordered a HOP-1200, not sure what version will arrive (R/S/N/W), but at ~$7 including shipping you can't go wrong, I'll probably also order a HOP-1000 and then some more...

This was asked a long time ago:

Between the front display, which is transparent, and the display there is a small kindof dark-red thin plastic window which seems to cause the foggyness i see. Maybe this plastic window gets "old" - due to the exposure of light, smoke, whatever - and loses its clearity.

The only option i see now is #2. The question is, will it help?

Maybe, just maybe, this window can be replaced by a hard plastic window, which doesn't age like that.

(I got some photos, i will upload them later)

Cheers

If you or anyone else wants to know how to take it apart, let me know, I can probably make a guide.
I can already tell you that it's NOT for the faint of heart! But then again, it's really not that hard...

HOP-1200R: $25.00 on eBay, shipped.
HOP-1200S: $17.00 on eBay, shipped.

So I ordered one each of these;

Tonight I also did a 'dry run' on the replacement:

-Removed the Traverse mechanism and put it back.
-Removed the Laser Head (alone) and put it back.

Both were fairly straightforward. It seems to me the laser head -only- (read:cheaper) replacement may be the EASIER replacement! (Less ribbon cables to worry about.)

After complete disassembly and reassembly, I'm listening to Alison Krauss+Union Station Live on SACD right now as I type this on the unit that was in pieces, down to the laser.

For anyone who may be reading, I found this in my research:

Laser Pickup for Denon units:

Denon DVD-2900: Hitachi HOP-1000 or Hitachi HOP-1120 ~($40)
Denon DVD-2910: Hitachi HOP-1200R (~$25) or Hitachi HOP-1200S (~$17) or Hitachi HOP-1200W (~$15)
Denon DVD-3910: Hitachi HOP-1200R (~$25) or Hitachi HOP-1200S (~$17) or Hitachi HOP-1200W (~$15)
Denon DVD-2930: Sanyo SF-HD65 (~$8)
Denon DVD-3930: Sanyo SF-HD65 (~$8)

(The Hitachi HOP-1000 may work in the 2910 and 3910 also but I can't find one; it's more robust, made of metal, more solid. )

-Replacing these should not require any realignment.

-You MUST remove the grounding solder points on the laser heads before they'll work; I've done this on other machines before (such as my XA777ES) - this is an ESD protection mechanism, it's best to use a 'solder sucker' sort of solder remover rather than a wick. This is probably the toughest part of the entire procedure.

... So, we may be down to $17 on the fix for this. More to come.

That is very interesting.
Do you have any other Pickup unit info like that on other DENON players ?

for now I might be looking at a replacement for a DVD2500BT

the BD player part needs more than 20mn of running before it start picking up correctly any BD,

after that it can read smoothly any BD flawlessly but at cold start it can attempt 20 time to read a BD and never pick it up.


regards.

DBP-1610
