Question about Onkyo DX-C390 6-Disc CD Changer

1 Answer

What is the most likely cause of a "NO DISK" error with the Onkyo DX-C390 6-Disk changer? Would it be the laser pickup assembly?

Sometimes the unit will read and play the disc. I can hear the laser assembly as it focuses on the disc. When the unit fails to scan and play the disc, I hear 3 little clicking sounds (which I assume is the laser attempting to focus on the disc, but can't) and then it rotates the carousel to check for the next disc. On the rare occasion that it scans the disc, it plays it just fine for the most part. Every now and then it will skip a little.

Could be dirty laser lens, dying laser, faulty component,
Due to the complexity of multi-disk changers, it may be best to have the device looked at.
You can try running a cleaning disk through it first, but from your post, it sounds like this unit may have multiple problems and need tested by a physical person.

    Thanks for the idea, Jeff. I have indeed used a cleaning disk. I am tending to think that it's the laser pickup assembly. Now it is a solid hard failure. I can hear 3 little clicks, which is most likely the laser trying to focus on the disk and establish a focus lock. After 3 little clicks, the carousel rotates to the next 5 slots, each of which are empty.

    I have ordered a new laser pickup assembly from e-Bay. I'm going to replace the laser. As far as the machine moving the disc around to the actual playing mechanism, there's no problem there. I've watched the mechanism with the cover off. It acts like that the initial focus lock needed to read the table of contents fails. If that initial focus lock fails, nothing else that's supposed to happen after that will be allowed to take place.

No laser, means no laser. Typical symptom of laser failure. Most CD players can have the laser replaced fairly easily and cheaply.
Contact your local technician, and he should be able to replace it quickly.

Possible broken drive belt, that's what caused the same error on my unit. Very easy to replace, just take off the top cover and the motor and belt are readily accessible.

Error message (protect) cd plays then goes silent then plays again. have cleaned laser several times with cd cleaner disk.


Dirty lasers don't cause "protection" problems. Are you sure thay message is displayed on the CD player? That word is nowhere in its manual.

CD sounds jumpy, missing segments of the song then the CD resumes. Cleaned CD's but it continues to happen.


The problem is in the laser pickup assembly, overtime the laser becomes weaker until it can no longer track the disc properly. The only option is replace the assembly, "very expensive" or purchase a new cd changer, "much cheaper option"

With no disk loaded and the dvd player turned on, the dynex blue screen turns on then the laser jams into one position and there is loud static sound.


Unfortunately the stepper rail linkage is defective that moves the laser pickup assembly, the only solution is replace the whole laser pickup assembly which is not cost effective, cheaper to buy a new portable dvd player.

It won't play disks and just makes a lot of mechanical noises as it goes from disk to disk trying to play one.


The mechanical parts are working but the laser pickup assembly is not reading the disc. The possible causes are, dirty laser pickup lens, bad pladder motor, or no b+ to the motor, or worn out laser assembly system. Because of the expense of buying the Bose units I highly recommend a professional service man to work on the item.
