Wont play any games just says open tray - Microsoft Xbox 360 Console

My xbox plays some games , but i have a new modern warfare 2 cd and not really much scratches on it, but it wont load. keeps saying open tray.

Yes if you have this problem it is because of the sensors on the back of the drive you can fix it with a good repair guide or you can send it in and they will fix it for you.

Had the same problem and didn't have no clue because it never says or display disk Read Errors, after some try and error I found out it was a dirty laser lens.. So before you try to do something else or pay somebody to repair it for you.. try this simple solution first, go out and buy a Lens cleaning kit at any video game store near you, it worked for me, so it should for you too..

Hope this help.
