probably some levers of the plastic cover are misaligned. try to remove it (levers snap into ejected position), press eject for >12s (loading motor should run for several seconds, unloading the tray), then replace the lid without any force. now you can test whether disks are pulled in correctly.
Mhh, got the BD here now. Put it back together again, test it, and there is a weird sound (like there is something want to move but can't, like TRRRRRRRRRR, or something xd). So now I have it in parts here again, but I don't know HOW to put it back together the right way. Anyone have a good tut or something?
hmm, the problem is, I think, there is a clip on the front of the drive (without case, what lifts the protect the enter of the drive, weird description..). When i lift that clip up, the disc come out, when that clip is down, the disc won't come out.. But the problem is it wil only lift when I do it manually.. Will look at youtube now to assemble it again.
