California Audio Labs CL-10 troubles - not reading

I recently bought a CL-10 off of Audiogon. It seemed to work fine initially. It started to have troubles after an hour or so of all-disc random play. The player would not be able to read any disc in the tray after a while. Following a cooldown (usually overnight) the CL-10 would then function normally for a while and the problem would recurr. At this time the CL-10 will not read any CD. Befroe I take it in for service I wanted to know if anyone has had similar problems and what they did about it.

Thanks
