I had my local electronics repair shop fix my CAL CL 10 5-disc cd changer a few years ago. They said they replaced the laser head and a capacitor -- both were off-the-shelf parts they had in stock. Before I entrusted the unit to them, I partially disassembled it myself out of curiosity (dumb!), and I can attest that the assembly was complex such that their repair must have been at least moderately time consuming. I don't remember exactly, but the cost was between $100 and $200. I didn't think that was out of line at the time. Good luck.
