I had exactly the same problem with my Denon DCD-910. Fixing it is easy, but it took me a while to find out;

In the power supply +10V and -10V unstabilized lines (in front of the 7805 and 7905 +5V and -5V regulators on the heatsink),

there are 2 ICP-N15 devices (IC protectors: very fast acting electronic fuses 0.6A). PCB component print is IC502 and IC503 if I remenber well. They tend to deteriorate over time and break, or a current peak could have made them tripping.

The +10V/-10V (+13/-13V really) is used for driving the loading/spindle/sliding motors and focus/tracking coils ONLY. +/-5V was still OK, that's why you can still see the display.

They have a TO92 transistor housing, but only 2 leads. ICP-N15 are hard to find; You could also use ICP-F15, but these have a different housing.

You could order the original ICP-N15 at utsource.net
An alternative could be to mount 2 polyswitches (also called multifuse), a PTC type current limiting and recoverable circuit breaker, like Bourns MF-R065, rated 0.65 A

I replaced them with 2 radial 800mA PCB solder mount fuses (1$/pc), and everything works fine again. Yet another piece of excellent equipment not to be thrown away ;-)

You have to unmount the PCB from the CD player housing (about 8 screws and disconnect all 10 connectors) to be able to replace the fuses.
While it is disassembled, check for broken solderings, especially on high power devices ( like voltage regulators mounted on heatsink or power transistors)


I hope it works for you too.

I just bougth a marantz cdr 300 cd recorder,everything seems to be working fine, but I'm not able to listen what I just recordered on any other cd player.Marantz cd 72 mr 2020.Thanks


Hi,
It sounds like you haven't followed the last step to the burning procedure. All you need to do once you've completed burning your disc is to Finalize the disc. Read below why you need to finalize as well as the steps to follow in order to finalize the disc.
Hope this helps ;)
How to Finalize Finalizing is writing the TOC (table of contents) on a disc so a CD player can recognize the number of tracks, the total time for each track, and their location on the disc. A recorded disc must be finalized to playback on a standard CD player. Once finalized a CD-R disc can be played on CD players that support CD-R playback. CD-RW discs can only be played on CD players that support CD-RW playback. Consult your CD player owner's manual to confirm supported formats. Finalizing is necessary to: • be able to play a recorded CD-R or CD-RW disc on a CD player • prevent further recording on a disc • avoid erasing tracks on a CD-RW disc • record text information onto a disc you record Notes: • A finalized CD-R disc can never be recorded onto again. • A finalized CD-RW disc can be unfinalized for more recording. • The CDR300 can play back unfinalized CD-R or CD-RW discs. • SYNC REC+FINAL mode automatically finalizes.
Here are the steps in order to Finalize your disk
1 Push Stop. The display shows the number of tracks and their total playing time. 2 Push FINALIZE. FINALIZE is displayed for about 3 seconds.

When I try to play a CD I get an "err" message. Using store-bought CD's, not ones that have been copied. I have the Emerson PD6559BL portable CD player Love this CD player so I hope you...


Extract from your cd player manual:

"This CD player can play normal CDs p/us CD Recordable (CD-R)
and CD Rewriteable (CD-RW) discs. However the playability of CD-RIRW discs
may be affected by the type of software that was used in 'ripping' the tracks from
the original discs and 'burning' the tracks onto the blank media. Playability may
a/so be affected by the quality and condition of the blank media you use for
recording. 100% compatibility cannot be guaranteed, this is nof an indication of
any problems with your player."

So try to burn the disc with another software or buy different CD-r.
You also want to make sure that you Burned the tracks as audio files and not MP3 file, because your player can not read MP3s.

Hope this helps.

Dear Sir/Madam. I Would be Very Grateful if You Would Help Me to be Able To Find The Instruction Manual For The Denon DMD M30 Mini Disc Player/Recorder So that I Can Learn How to Record on this Unit. I...


Hi Neville,

I can't find the DMD-M30 manual on the Denon website.

A lot of the other "free manuals" websites are not really very good and are just trying to get your email address so that they can send you spam email.

I would recommend trying to contact Denon directly.

Their details are:

Denon UK
Division of D&M Audiovisual Ltd.
First Floor, Imperial House
4-10 Donegall Square East
Belfast BT1 5HD
Northern Ireland
Tel.: +44 (0)2890 279830 begin_of_the_skype_highlighting +44 (0)2890 279830 end_of_the_skype_highlighting
Fax: +44 (0)2890 312643

If Denon can't help you then I've found a company who will sell you a manual for £5.11. The link to their website is here:
http://www.chsinteractive.co.uk/electrical-components/misc/dmdm30-instruction-book-denon.htm

Alternatively if you think your unit may have a fault but still wish to record on minidiscs then I have found a DMD-M30 for sale on ebay with a current bid price of just £1.70 with 3 days remaining in the auction. The link is here:
http://cgi.ebay.co.uk/DENON-MINI-DISC-RECORDER-PLAYER-DMD-30-/260746909956?pt=UK_CE_Cassette_RL&hash=item3cb5ba1904

Please rate my answer if this has been helpful.

Kind regards,

Chris

Denon AVR-1908 speaker issue


Before we play taps and throw dirt on top of the Denon, perhaps a bit more triage is in order. I'm not certain who the patient is. Especially when you have "speaker issue" in the title. Are you saying there are some speakers that don't work ONLY with BluRay?

If it has NEVER worked the (unnamed) BD player or its cable(s) could be at fault, too.

What 'connections' are we talking about. HDMI, coaxial- or optical audio, 5.1 analog; to what input on the Denon assigned to what function?

Have you tried all audio paths out of the BD player? Is it configured to squawk in the right digital mode?

Do you have any other digital audio sources (CD/DVD) you could use to certify the audio paths that don't work with the BD player?

Compact disc player, put disc in, pressed play the display is showing 00 0000 but not playing


Ensure first that there is no disk stuck inside.

If there is a disk stuck inside, try pressing repeatedly the eject button while you power up the unit. Do this a couple of time.

If there is no disk inside, or you get this same problem with all disks, then the lens are dirty, try using a lens cleaning product like the ones here.
