I once had an old clapped out xbox 360 that I had to help push the disk tray shut to get it to read a disk. The same motor that closes the tray typically also moves the laser up and down. If you notice that the tray appears to be getting slower, it may not be moving the laser into place. This seems more common if you usually push the tray to close it, rather than pushing the eject button. Try ejecting the tray. Then close it by pushing it, giving it some assistance so it closes swiftly and snug. This will ensure the laser flips up into position.
