so i have this dvd tray that for some reason wont open and its really starting to make me mad. i dont know why it wont open. i took the shell off of my 360 and the dvd drive. it has the gear in there and it spins fine, but it refuses to open. when i turn on my 360, the green center light flashes the whole time. what should i do to this thing? if the motor is burned out, (which might be the problem, but i dont know where it is on the drive to check) i have a second one in which i could replace it. so what should/can i do to fix it? thanks.
