Sounds like the pickup lens is dirty or failing.

The laser pickup assembly is at the end of life, remove top to expose the laser lens, use a Q-Tip and rubbing alcohol and gently clean, allow several minutes to dry, if no change! far cheaper to replace the cd changer.

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.

You need to take it to a repair shop, you just can't put the lens back, it needs to be cleaned and aligned.

Sorry for such a simple solution, but it has saved my but multiple times. Try cleaning the disk reader laser with a smooth clothe rag or material. Clean the dust or whatever may be on it. If that doesn't work, then I hope someone with more knowledge on this matter will help.
