Shanling SCD-T200 not reading discs

I bought a Shanling SCD-T200 in 2005 and it has performed flawlessly until recently. I am the original owner and no mods have been done. Everything seems to work except it began reading only some discs. Some discs I was able to play if I gave the disc a quick spin to start it, and now it will not read any disc. It gives me the error message no disc inserted. I am not an electronics expert. Has anyone had this problem? Is it fixable, or do I have a new, beautiful boat anchor? Any help would be greatly appreciated.
