The system tries to read the cd's but it comes up as "no disc" i
The system recognizes there is a disc in the designated slots and attempts to read the discs but it comes up as "no disc" after about 15 seconds of attempting to read. To me it seems like a lens problem

If your Bose 2020 radio is not connecting to your 2016 multi-CD changer and is not recognizing discs 2, 3, or 4, there are a few things you can try to troubleshoot the issue:
1. Check the connections: Make sure that the multi-CD changer is properly connected to the Bose 2020 radio. Check the connections for any loose or disconnected cables.
2. Check the disc format: Make sure that the discs you are trying to play are in a format that is compatible with the CD changer. Some CD changers may not be able to read certain formats or may have trouble reading scratched or damaged discs.
3. Clean the discs: Try cleaning the discs to remove any dust, dirt, or fingerprints. Use a soft, lint-free cloth and wipe from the center of the disc to the outer edge.
4. Clean the CD changer: Dust and debris can build up inside the CD changer, causing it to have trouble reading discs. Try using a CD cleaning disc or a can of compressed air to remove any dust or debris that may be inside the CD changer.
5. Reset the system: Try resetting the Bose 2020 radio and the CD changer. Unplug the power cords from both devices, wait a few minutes, and then plug them back in.
If none of these solutions work, there may be a problem with the CD changer or the radio. You may need to contact Bose customer support for further assistance or take the devices to a qualified technician for repair.
The CD unit has two optics, a tracking laser and a reading laser. It sounds like tracking it working, but reading isn't. Try an optics cleaning disc. It has gentle brushes to clean the dust off. You can also get them at Walmart.

CD/DVD Is Not Recognized
Many times, after inserting a disc into the CD or DVD drive, the disc is not recognized by that drive. CD-read and DVD-read issues can be caused by many sources. Perform the procedures presented in this General Computer Advice article when troubleshooting CD-read and DVD-read issues.
Begin with the first procedure and continue through the list. Try using the CD or DVD after each procedure is completed. For any procedure that requires changing current system settings, record the original settings before completing the procedure.
Verify that the correct disc (CD/DVD) is used when prompted to insert the disc.
For programs on DVD, verify that the drive containing the DVD is a DVD drive and not a CD-ROM drive. Most DVD drives will haveDVD printed on the front of the drive. For programs on DVD, consider the following:
DVD drives can read both DVD's and CD's.
CD-ROM drives can read only CD's.
If multiple disc drives (e.g., CD-ROM and CD-RW, or DVD and DVD-RW, or CD-ROM and DVD-RW, etc.) exist on the computer that can read the disc (refer to the items under Step 2), insert the CD or DVD into the other drive and try the program again.
If you are attempting to install a program and the installation does not begin after inserting the CD/DVD into the proper drive, refer to the program's instructions for the installation procedure.
Clean the CD/DVD in the following manner:
Place a small amount of nonabrasive liquid soap on the shiny side of the CD/DVD.
Using your fingertips and warm water, gently rub the soap on the CD/DVD in a circular motion.
Rinse the CD/DVD thoroughly and dry it using a clean, soft T-shirt or lint-free towel. (Do not use paper towels or tissue paper.)
Try to use a different CD or DVD in the drive to see if that disc can be read.
If possible, insert the problem CD or DVD into the DVD or CD drive of another computer to see if the issue persists.
The auto-run feature is probably forcing the drive to attempt to read the CD, and if the disc is corrupt, can cause the system to "freeze" while it attempts (and fails) to read the bad disc.
If you've tried mulitple discs, or one that you know works in another CD-ROM drive, it could be the CD drive itself. If that's the case, you can pick up a good CD/DVD writable drive for $25-$50, and takes 5 minutes to swap out.
Open system profiler and check to see if the drive is recognized on the ATA bus. If it is you can attempt to clean it using a cleaning disc designed for this purpose. If the drive is not recognized, then you will need to take it to a reputable repairer or, get an external drive.
Ok, the reason is quite simple. The Philips DVD8421 does not recognise the DVD-R format.Not all DVD/CD burners read all discs. It does recognise DVD+R though. So all you need to do is use these discs instead. This should solve your problem.
I have a AWM-2700U (3 disc changer) that was doing the same thing. I removed the cover and found that the laser lens for the CD player had come out of it "slot". I cleaned it with alcohol and a cotton swab and replaced it in the slot and it has worked for the past 3 months since. Hope it works for you.
