CEC TL5100Z -- repair or replace?

I am the second owner of this piece, which I have been using as a transport for my DAC. A couple of days ago it stopped reading CDs. I tried cleaning the laser, which produced no cahnge. Does anyone know who works on units like this? Does it make sense to repair it, as opposed to replacing it? At this point, I have been running it into a balanced Theta Gen III. I am happy with the sound, and not terribly interested in a newer sound.

Thanks in advance.
