Question about Sony CDP-CX450 400-Disc CD Changer

Open Question

Changer tries to load disc one when empty

1. when no CD is in the changer is starts at disk 1 and searches for a disk on all random number consecutively. 1,3,5,7,9, etc instead of displying "No Disc" 2. If a disk is loaded in slot 1 it will play it and appears to be working normally. 3. when a few disks are loaded and slot 1 is empty is does the odd number search. I think it is probably the Disc sensor. any ideas?

Hi there.

I reckon that they are not being put back correctly by the loading mechanism! This is a common problem with these units. It is highly unlikely that they are actually falling off the carousel.

Open the unit, and watch it as it loads and replaces the cd's from the carousel. You will probably find that instead of grabbing the disc off of the spindle and putting it back, it might be grabbing before the cd is even in its grip. This then simply bumps the cd out of the way, and it will fall inside of the unit.

The good news is that it can be fixed with a bit of very gentle bending and persuading. But be very carefull when doing this!

Good Luck!

how long have you been using this player? I suspect the laser (lens) of the player. I think the laser (lens) is weak that's why it is refusing to play any more CD....
Get a lens cleaner, use it to clean the lens. If that doesn't solve the problem, get a screw driver, open the player's cover so that you can gain access to the lens, use a cotton board to clean the surface of the lens. This should clean dust or dirt that might be on the lens. You can add very little liquid to the cotton board like mentholated spirit and dry the lens with another cotton board that has not liquid on it.
If non of the above solves the problem, then it means the lens is weak beyond cleaning. Know that you need to replace the laser to a brand new one.
To replace the lens, remove the bad laser, use it as a sample to get exactly the same type and do the replacement. Note that replacing a laser (lens) needs a professional touch, so if you cannot replace the laser, get it to a repairman to fix it for you.
Once this us done, your player will play all CD's again without any problems.
I hope you understand the above.

5 disc cd changer CC4000 will not read

All players need cleaned from time totime. Do NOT try to clean it with anything other than a CD / DVD lens cleaner. They are available almost everywhere that sellsBlank media. It will clean the lens without scratching or smearing it.

CD changer has gone wacky; won't change discs; Pioneer PD-F5507

Look for either a bad solder joint, or a bad connection somewhere.

Will not play anything.

There is a rubber belt inside the loading mechanism, you should replace it by the new one. Cleaning the optical unit can be of great help also. If you need more info, please advice.
