Question about Denon DCM-390 5-Disc CD Player

1 Answer

Denon DCM 390 not longer reads discs--HELP!

It read and played CDs a week ago. Nothing has changed and it no longer reads any CDs.

In retrospect, about 6 weeks ago, it failed to read an MP3 CD, but it read and played regular CDs fine until today.

    OK, I ran the CD lens cleaner and the player balked at even reading it. After several attempts, it read the disc (confirming that there were three tracks), but did not play it. Now what? This player isn't very old and hasn't seen a ton of use -- but it's got the features I wanted....all except the, you know, ability to actually PLAY anything...

    I'm imagining that any official repair will cost more than the player. Should I try monkeying with this myself? The player's junk one way or another unless I somehow miraculously fix it.

    Any site you recommend to fix-it how to's?

Hi there, this lens may be dirty or it may have a thin layer of heat film that is causing it to not read in a consistent manner. i would try to clean the lens with a good CD lens cleaner. if the cleansing doesn't restore the lens to its original reading state, this will confirm lens assembly failure and you will need to replace this assembly.

Won't play, just keeps skipping discs


Good morning Lori.

My troubleshooting thoughts run something like this:
  1. It sounds like it's skipping on every CD.
  2. This is (according to the manual Denon DCM 390 Operating Instructions Manual Troubleshooting a cauousel-type system, so it has a tray that you manually place CDs into, rather than a cassette that you put all the CDs into and then insert into the player.
  3. Most of the manual Troubleshooting section puts the blame for discs not playing upon dirty or damaged discs - you're told to re-load it, clean the disc, try another disc.
  4. If this is just one set of discs, then it's worth it to pull out at least a couple and try other discs that are clean, don't have scratches, and, hopefully, that you know work on another player. If they work, then, kudos to the manual, the discs may need cleaning or replacement.
  5. If you're playing home-burned CDs, you may need to finalize them for play. Computer CD burners can often give you a lot more leeway in what they're willing to play, since there is a much more sophisticated bunch of code running the burner that will have some expectation that in-process discs might end up there.
  6. Last, but, IMO, most likely - steady skipping on every CD can mean that the CD laser lens is dirty. Over time, dust on CDs or from the air drawn through the chassis can build up on the lens, which has a fairly small gap from lens to Disc surface. In something like a DiscMan or other portable CD player, the lens is usually pretty obvious and can be blown off with some canned air or brushed with a micro-fiber camera lens cleaning brush. In this case, it's what I suspect is the problem. Depending on what gear you might have, or how much you'd want to spend on it, what I'd suggest to try fixing this possibility would be :
    1. Use a commercial CD Lens cleaner. They'll likely run 6 to 10 dollars. A list here Amazon com cd lens cleaner Electronics has lots of possibilities. You'll want one of the ones that looks like a CD with a small brush attached to the bottom, possibly some fluid. You'll put it in the player, hit play, it'll at least attempt to play for like 5 to 30 seconds, and end. The brush will be spun past the lens multiple times, removing dust / gunk buildup.
    2. Use canned air. I'm talking commercial stuff expressly meant for cleaning computers and other gear that will suffer from a blast of oil-laden air from a garage air-tool compressor. Examples here Amazon com canned air Electronics
    3. Open the system up. I can't give too much guidance other than I did it years ago on my system - make sure it's unplugged before starting. Remove screws attaching black cover to chassis, and you may be able to get in with a brush to clean the lens. Don't go this direction unless you're confident of your DIY skills.
    4. In any case, try to stick with dry cleaning methods like the cleaner disc or canned air. If you do anything with direct contact, stick to clean microfiber cloth or brushes, and be gentle - no scrubbing motions. It's a tiny lens, and a scratch or mis-alignment from forceful handling will be the end of it. If a liquid must be involved and isn't part of a commercial kit, nothing but distilled water. Many, if not most, of the CD lenses are molded plastic, and glass cleaners, likely as not, will attack the lens surface and roughen or fog it.
  7. Last note - the reviews on Amazon for this unit are not kind. It sounds like the skipping and failure to play is not uncommon with this particular Denon model. If the unit is still under warranty, I'd grab the opportunity to have someone fix it for real and deal with any faulty mechanisms. If not, you have little to lose with the above, but the reviews suggest that replacing with the same model might not be the best idea.
Good Luck, and Happy Holidays

The laser's reflected signal is no longer detected. All you can do is to clean the unit with a lens disk like

If this fails then the laser diode has failed and the optical unit is dead - it will have to be replaced.

Not read disk No lee los discos No reconoce los


Hi,

how long have you been using this player? The problem should be from the lens (laser).

The lens is weak and that's why it cannot read/load Cd's. The weak lens is also what's making it skip.

Get a lens cleaner and use it to clean the lens, but if the lens still does the same thing even after using the lens cleaner, then it means you would have to change the whole lens completely to a brand new one.

By so doing your player would play all Cd's with no problem at all.

Take care

Denon DCM-280. Tray won't open, there are CDs in


If you don't wanna send it for service, open the chassis of the player and free the CDs from the tray. Its highly likely that the CDs came off the trays and got stuck inside.

Denon DCM 5000 error code


The disc is loaded upside-down in the disc rack or the disc is dirty or scratched, try another disc and make sure the top side (label side with printing) is facing towards the back of the rack, away from you. The bottom or data side should face out towards the front of the rack. If that does not work then your laser picups inside may need cleaning. Make sure your disc is clean and now scratches.
