The player had been updated by an authorized tech to 24 bit many years ago. Not sure if this matters regarding the new optical laser lens pickup.
@kingsleuy Here's a new observation that suggests it might not be the laser?? If I play a CD that it is usually able to read for a few minutes, then quickly substitute a CD that usually gives me the No Disc error, then it plays it!!! Otherwise, inserting that same problematic CD into the "cold" player won't read and the disc does not spin. There has got to be a rational explanation. Does the drive need to warm up? Does the laser remain on for a short period after CD removal and I'm catching it before it powers down? I'm at a loss to explain this latest observation.
