Just to say I have used Sony ES changers for many years. First was a CD89ES, Then 2 CD9ES now I still have the (slighly misfunctioning 9's) and a demo SCD333ES.
The problem I have had is never the laser, it's the flat cable from the laser sled to the rest of the electronics.
That cable is flexed every time the player changes CDs, and the connection fails intermittently (while in play) as the cable is flexed .
