ive seen it mentioned a few times already that the lite-on drives(in my case 2 dg-16d2s drives) have a problem with the open tray error even after replacing the lens. the lens seems to get stuck in the far back position from what i can tell. ive been playing around with one today and tried bending the piece of the metal frame that holds the rail(back right side) so it moves the lens forward a little. from the little testing ive done it seems to resolve the problem. i had noticed on a previous box that the lens was stuck past the edge of the disc and when it trys to read the disc the lens cant see any data on the disc and therefore gives the open tray error. has anyone else done this or what methods have you tried besides replacing the drive?
