My Sony DVP-9000es is sick, please help

I've had this player for a year or so and it has worked flawlessly until this evening. It had been powered up all day and worked fine this morning but when I popped in a cd a few minutes ago it wouldn't play. The play light came on but the display read "ERROR." Tried a different cd, same result. Then I tried a SACD, stil no play.
It seems to be confused or simply not reading discs. Anybody know if this thing has a RAM clear type function? Any other ideas? Thanks.
