It has a lot of info on what could be the problem and how to fix it

Replace you lazer bro its dead

Unplug all your xbox cables make sure there are no games in it, then face it so the disc drive is face down toward the floor and drop 6-8 inches on a carpeted floor. This should unjam the laser. The reason why it doesnt work is because the rail the laser moves on is stuck so it wont go over and read any disc, therefore thinking there is o game in there.This fix is only temmorly and It will get stuck in the next 5 weeks after so it is better to get a new xbox

Also if you have a T tork 8 screw driver with the security hole you can manually take it apart and move the stuck laser,*Note to do this you must cut some security stickers that will make your warranty VOID

this sounds really stupid but when this happened to my brothers xbox i put a bit a thin card in to the disk tray and just move it in and out and this makes everything thet might b in the way out of the way and things like that!

you should try it, it worked for me!

i know wat to do its happened to me just put a game in ther once its in dnt close it but tap the disc so the xbox know its in ther then close it message if it works

I Had the same problem!

I Fixed it by opening my xbox up and taking the disk tray out...then just put it back in lol!

Also keep you xbox horizontal!!

what I did was tap on the xbox until it read my game it worked but i got tired of doing it so I got a new one

My xbox does this to, has done for about a year now, i just hit it on the top where the disk would be, it works but you need to do it a few times. ive got used to it now but got a new one and gave the broke one to my brother;)

Best thing to do is to replace the laser.

Also you will need this to open your xbox.

And a small screwdriver would be handy too.

have you taken apart your Xbox?

if so have you turned it on with out the disk drive if so that's why it wont work.

the only way to fix this is to flash your Xbox 360's disk drive
