Denon 2900

[caoauto]

Hi all, I have problem with my denon 2900 DVD that play very well on DVD but it does have problem of reading the CD redbook or copy CD or SACD. Where should I start looking at? Any one in here have the schematic for sale? or where should I buy ? should I do some upgrade? like start to change those opamps? remove the caps ? change those diodes?. Thanks for any help in advance.

You are addressing two questions here:

1) A playing problem you have with your Denon. That is not likely to be solved by any upgrades.

2) Upgrading parts to improve the sound.

I have similar problem with my Pioneer DV525, that refuses to play many CDs I have, but plays any DVD I put in. Unusually sometimes plays a CD copy of the same original I have and not the original.

Thanks for replys so far. Yes I have 2 isues and though upgrade might solve the problem, but if not I better fix it first before talking about upgrading. You are right, play good on DVD but not on CD That is acxactly what I have problem with, so what did you fix ? or how to deal with ?

Well, I don't know how to deal with that CD problem in the Pioneer. But as long as it plays the DVDs fine I will stick with it, and use another player for the CDs.

Right now I started another thread here that didn't get much attention, about a likely candidate: a Marantz LV500. It might be great player, solid and all that, as long as it doesn't threat me with another problem of its own: locking itself up.

But when it played, for CDs it was better than the Pioneer ever was.

Hi, Any one know the part number of the denon schematic 2900?. Thanks in advance.

You should contact DENON - try the web site, give them a call and they'll send you a CD with pdf user manual.

The problem is related to a different reflectivity of CD ROM's. Even music CD's you buy in shops vary A LOT when it comes to reflectivity. I have discovered that some bad music CD ROM's have 25% less reflectivity than majority of other music CD's. This could be a problem - especially when the pick-up has to find the beginning of a track! (that is - if it manages to read the TOC at all…)

Hi every one. Just got the service manual schematic for it. find out bad laser in the CD side and it is kind weak on the DVD side too, I try to see if any magnet that stuck junk in it but it is very clean.
Now the question is how do I get cheaper laser to replace it? because I check the part they want for $100.00 for the whole Assembly, or should I pull the audio board out to build as a DAC for another transport? because it sounds very good, alot music and 8 times up sampling 24 bids 192Khz DAC, and disconect the multi chanel. Thanks again for all the helps.

hi all
looking to solve the same problem but can't yet find a parts supplier willing to ship to England - anyone know of one who can supply the schematic on CD and/or the part# 9KC2A063B (updated transport assembly)?
also if anyone has a "spare" copy of the DVD2900 schematic on CD I could offer some $$ in exchange - feel free to email me at lardy_one@(no spam thanks)dsl.pipex.com, minus the (no spam thanks) ...

thank you
