I had a different problem with my cd tray. It would open and close, but not recognize when a disk was inside. Some prodding and it would get the hint usually, soon I had to replace the console. Hopefully yours is just having a bad day and isn't dying like mine.
I had the same problem.did not open,clicks,not reading the game in there,,
ok i did get lucky after a few tries it opened and i found 2 discs in there.
working ok now. hope its something simple for you.
