Thanks Daniel and Shay for your suggestions. I have previously tried to boot from a CD (Disk Warrior, OS X install and the Hardware Test Tool CDs) by holding down C and also the cmd-opt-del key combination to no avail. I just tried the PMU reset without luck too.
Seems that the mechanism is looking for the place on the CD to start reading but can't find it. It doesn't spin up - at least not with any speed - as I don't hear the whirring of the spinning disk just the laser carriage moving back and forth. But it still burns!!! And it has to spin to do that!!! Bizarre. Thanks again for your help. This list is terrific.
