Warning: Sony SACD & pilot error

I turn off the display on my Sony 9000ES, so I had not realized that the failure to play SACD was my error. I tried to play the SACD layer of "Let It Bleed" with no success, so I turned off SACD, played the redbook layer then forgot to reset the Sony. Without feedback, I was unaware that the 9000 had displayed a disc dirty error code. With SACD off, the 9000 would recognize the SACD layer of other discs, then revert to red book. Once I turned the display on and realized the error, the 9000 has played every SACD I've tried, but not LIB -- not sure how you can clean an SACD layer.
