Phillips Laser Installation If you are receiving Disc cannot be recognized it may be dirty or damaged errors on your Phillips DVD drive you can replace the laser to resolve the issue.
What You'll need: Phillips Xbox DVD drive with failing laser Prepare your laser, Llamma lasers are shipped in a static protected state. Always use ESD precautions when working on electronics. Note the two blobs of solder that exist in the green circle on the left but are removed in the laser on the right (You can see a dark line that forms between the two solder pads once the solder is removed)
Removing the solder is best accomplished by wiping a clean 15Watt or other low temperature soldering iron across the pads, the iron picks up the solder.
Remove four Phillips #1 screws
One of them is under the warranty void if seal damaged sticker
Remove the top cover.
The CD/DVD tray must now be extended to gain access to the laser. By sliding the actuator in the direction of the arrow below...
...the tray moves about a 1/4 inch forward and can be opened the rest of the way just by pulling on it and it will slide freely.
Now with the tray all the way open we see the laser and the green PCB below. There are two silver parallel rails the laser moves on. One of the rails must be removed to gain access to the laser itself. Note the area circled in green, we need to remove the rail from there and it will easily slide out of the front one. The rail on the left of the drive can be left in place.
The rail is held in place by a small metal spring loaded tab. The metal is in the shape of a number seven (7) the small leg presses against the plastic and holds the rail from escaping, to remove we need to elevate the metal tab over the plastic so it can slide to the left. You will also notice a small bead of rubbery glue holding the metal tab down, use a pic or screw driver to scrape this off making removal easier.
Getting the tab over the plastic is a two handed operation. I used two small regular precision screw drivers to lift and one to leverage to the side. In this photo you can see the tab is lifted over the plastic riser, and held in place by a screw driver, the rail can now be lifted up.
In this photo the rail has been freed but the front is still attached, pulling the rail about a quarter inch back releases the front. and the opposite side is also free since there is a U shaped holder that touches the rail.
With the laser removed we must swap over the gear and springs, a single Phillips #00 holds this in place. Keep in mind if using one of the Llamma's lasers they are brand new and you will be cutting threads when in stalling this screw so it may be a bit harder than expected to insert.
Now that the gear and rail has been swapped over to the new laser it is time to re-install the laser and rail. Start by fitting the laser U shaped notch back into the lower rail in this photo. Next insert the top rail into the standoff at the top right in this picture. You will now have the only rear top standoff, and rail holder to contend with.
Using the same lifting/pressure method as before we need to push the metal tab out of the way. The rail can then be pushed into place.
Note that the rail is in its spot but sitting there loosely. The metal tab has yet to be locked in place.
Using a precision screw driver, depress the tab so it is below the plastic, you may want to also replace the glue that holds the metal in its place.
Reassemble and install in your Xbox!
