CDP transports when do know they died

Swing mechanisms are alledged to have that problem. I think it may be blamed more times than it deserves to be.

However, I have opened players that someone oiled the hell out of the platter motor, covering the laser head with oil. I did have one player come back with a noisy platter motor bearing. That is uncommon. One had one of the photodiodes dead. It would not read all all, even though the laser output was good.

I only meant "a routine lube and oil" as a figure of speech :~)) Actually, mosts bearings these days are permanently lubricated anyway.

What sometimes happens w/ CDTs though, is that the laser assembly tracking rails or swing mechanism becomes stuck or sticky, and the laser can't move to the "lead-in" point of the CD to initialize play. So the platter motor justs shuts off "thinking" there's no disc in the machine

"Routine lube and oil" on the platter motor might come flying out, spraying everything when and if it does spin. Use caution.

A lot of times, there's nothing wrong with the laser (dead or dirty) or tracking electronics -- just dry lubricant and/or dirt on on the tracking guides/rails. At least check that out first. Maybe just needs a routine lube and oil.
