Phillips Xbox DVD Drive
Complete Dissassembly

Tools:
Phillips #1 Screwdriver
T6 Torx Driver

Llamma's Replacement Xbox Phillips DVD Lasers available here

	Remove four Screws
	Remove top cover
	All CD/DVD drives have some sort of mechanism to move the laser and hub up and down, the Phillips drive has one on the top, barely accessible at the front of the drive tray.  Slide this over as the arrow shows and the tray will move forward slightly, you can now move the tray forward and remove it if desired. (if replacing a laser it is not necessary to remove the tray but makes things easier)
	To completely remove the tray lift the catch on the right side of the drive.
	Now you should have a good view of the laser assembly note that on the Phillips drive there is a black gear rail that sometimes pops out of place and the drive begins showing Disc is Dirty or Damaged errors.  The gear rail simply needs to be put back in place for normal operation.
	Not Like that
	Like this
	Flip the drive over to remove the bottom cover.  Note the black tabs that are circled, these often bind and make the tray difficult to remove.  Push those in first then remove the tray.
	Now we should have a good view of the bottom PCB, note the screws circled in green, these must be removed only for total disassembly, if you are installing a new laser it is not necessary to remove the screws.
	Next we need to remove three ribbon cables
	To remove them be sure to dislodge the wedge that holds them in place.  Start on one side and then the other.  This can easily be accomplished with a fingernail or delicately with a screw driver.
	Now all the cables have been detatched
	Take the end of the circuit board near the rear of the drive and flip it toward the front, this will reveal one more cord to detach.
	Now the laser assembly is exposed from the bottom of the drive.
	As well as the top
	If you wanted to try cleaning the lens and mirror this would be as far as you need to go. Blast the optics with compressed air attempting to direct the dust away from the lens (top) and mirror (bottom) Use a clean Q-tip and lens cleaner to clean the optics, you want to achieve a streak free surface.
	The next step is to dislodge four dampeners that hold the laser assembly in place
	Push them in the direction of the arrows and they will pop out and the laser assembly can be removed
	Now you should have a pile of parts that looks something like this

Reassembly is the reverse. 

Install the laser by pushing the rubber dampeners into their sockets.

Connect the circuit board to the white four wire connector on the chassis, lay the circuit board over the chassis and install the four black screws.  

You will find it is easier to make the middle ribbon cable reach the bottom of the circuit board when the laser is positioned toward the back of the drive, this gives a bit extra slack.

Install the bottom cover, make the black nubs fit through the bottom, those are the ones we pushed on to remove the bottom cover.

Re-install the black disc tray if it was removed, be sure to make the nub on the actuator we used to remove the tray fits back into the trough on the bottom of the tray.  Push the tray all the way in.

Install the top cover, install the four long silver screws.

Done!
