I have a CD-P670 6-disk changer which exhibits 2 problems, possibly related. When it's hot, it will either not play at all or will play a few tracks & play intermittently or display error 11. In moderate temperatures it plays the first 7 or 8 tracks, but not the remainder. Tried cleaning the lens multiple times with 3 different cleaning disks, inserting different audio CDs (commercially made & CD-Rs) & using other magazines with the same result. Inasmuch as the laser reads the first 7 or 8 tracks & the sound is good, I don't think that it's the problem.
I opened the changer & lubed the worm gear that moves the lens assembly with white lithium grease & it appears to move freely when driven by its motor. All other functions are OK & nothing looks worn or warped.

To my surprise, CD cleaner disc did it for me. It's a very old Philips one with a bit of furry stuff on the track side. I was amazed it even played, but it did and after letting it run for 20 secs, tried proper discs and it works fine. And this Pioneer PD-M603 is at least 15 years old!Looks like it would be hard to clean the lens manually because it's a long way inside.
Please remove the cartridge and check all the discs on it ., It is possible that over a period of time the disc could have warped. The disc while loading could be going into the wrong track and hence the mechanism needs a check on the path . Alignment of the loading tracks must be checked or corrected.
Try this:1. Remove the cover (2 screws on each side & 3 in the back).
2. Find a small white arm (more or less cylindrical, about 1" diameter, & about 3/4" long) and a longer (4-5"?) thin black arm in the center of the unit. These parts load/unload CDs to/from the playing area. You should see that a little knob on the white piece has jumped out of its track in the black piece.
3. Carefully put the knob on the white piece back in its track in the black piece. That should do it.
HI.This will occur when the optical assembly becomes unstable. this ((Whole One Piece)), assembly incorporates the spin/load motor, optics housing /arm, tracking device and tracking rail. This is connected to the loading dock assembly. This 'NO Disc', code is the result of a failed or burned out lens. It is possible that you have a dirty lens cap. you can try using a cleaning disk in this case to confirm actual lens failure. if the cleaning doesn't restore normal reading capabilities, this will confirm my diagnosis.
You will need to have the optical assembly replaced in this case. once replaced, your unit will be able to read and track once more.
sounds like the lens is dirty -try this out you kow them cans of stuff they use to clean keyboards with its like filtered air or something -try to blow out the guts of the cd changer with one of them cans and maybe it will help with functionality do the same with the cartridge emtied out and then run a cd lens cleaner disc and see if that does the trick-
Error 11 and or Error 17 is mean that CD is dirty or scratch, and the optic can not detect CD track. Solved problem: 1. Clean the CD 2. Change open source by push knob going to "CD" display or push "search" from remote to "CD" display 3. If still come out Error 11, change the MP3 CD by Original CD with clean track CD. 4. For the last step, clean the optic sensor by CD cleaner for a few minute. 5. Check and try to play the CD again.
Your code means an electrical/mechanical failure. Follow this:
1. If the cartridge is stucked try to force it out slowly with a fine screwdriver.
2. Once is out or if already out without forcing it, remove all remaining CD's.
3. Insert a laser lens CD cleaner.
4. Clean it at least 3 times.
5. The unit must be disconnected from the 12V signal to be reset it at least 5 minutes, then reconnect.
6. If problem re-appears repeat procedure once more. If problems still, your laser lens is damaged and need replacement. Probably from $40.00 to $55.00.
