Error code on front of disc changer C-31-00 - Sony DAV-DX150 System

The CD, when inserted, became either wedged or not seated properly and the sensors dont know how to respond. Here are the codes for Kenwood.
Changer Error Codes
• E-00: Poor Cable connection.
• E-01: Magazine not properly set in changer.
• E-02: No Disc in magazine.
• E-03: CD does not have selected track number.
• E-04: Disc is dirty, upside down or unreadable.
• E-10: No data is recorded on the MD. The player plays the next disc automatically.
• E-99: Changer malfunction, disc may be caught in machine or changer requires service.

If you have a steady hand... carfully unscrew and open up the unit just far enough so you can either pull, or nudge the CD tray enough for the CD to be seated in the tray properly...
Good luck...

Unfortunately 90% of the time when you get error codes from the CD player/changer it means that there is a mechanical failure in the CD player/changer unit itself and it usually requires CD player/changer rebuild or replacement...
First make sure you have entered the correct anti-theft code. If battery power has been disconnected recently than the stereo display will read CODE if the incorrect anti-theft code is entered the display will read ERR1 thru ERR3. If this is the case you'll have to get the correct anti-theft code. Note; If you enter the incorrect code three times the stereo locks up. Disconnect the battery for more than 30 seconds and then retry.
FYI;Never use adhesive labels or protective disc covers on recordable CD's. Recordable CD's are actually thicker than pre-recorded CD's. Automotive players and changers use rollers to draw the disc into the unit. The added thickness of an adhesive label or protective disc cover may cause the disc to jam. Also CD players and changers are exposed to high temperatures inside the vehicle. High temp will cause the labels adhesive to soften which may cause the labels edges to curl or cause it to bubble. Either one may cause the disc to jam. If the player can not be disassembled and have the discs removed successfully than it will have to be replaced. -hope this helps.

don,t want to which alpine 12 dics changer,on my ivad310 screen it said hi- temp, and no the front its say error when i which to my cd changer. so what is the problem is it , the alpine cd changer are the ivad310 needs to be reset are something let me know.

out of focus.
if all of your discs have the same error code 6, it is optical lens problem. have it checked to the nearest service center.

Some changers wont play copied cds. Try original discs.

maybe the lens in covered with dust , try to clean it , or it is broken. Who knows , break the device and see it for yourself. good luck

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.
