I had this. I sent it to Sony for repair. They said they upgraded the software on the 975. I couldn't fix it myself. The display showed "TRAY LOCKED". that's it. I couldn't do a thing. In some case you can accidentally lock the tray with combo of bottons on the remote, but check your manual for exact message. If that's not it and it's still under warranty send it to sony. But I got to tell you, the picture quality on this machine throught the HDMI cable is outstanding, but the build quality is terrible. It's basically a piece of crap as far as build. Sorry, but that is my opinion based on the tricks this unit performed over the past year and 1/2.
