This guide shows you how to replace the laser unit in the Playstation 2.

Tools: Feinmechanik Schraubendreher Set; Lötkolben und Entlötlitze

Parts: PS2 SLIMLINE ERSATZLASER - PVR-802W

Step 1

• Turn off your PlayStation 2 and remove the disc and Memory Card.
• Turn over the PlayStation 2 and put it on a soft surface (e.g. a towel).

Step 2

• Locate the six covers.
• Two are located underneath the feet.
• One cover is located underneath the Void sticker.

Step 3

• Remove the Void sticker with a Spudger and some cleaning alcohol
• CAUTION: Removing the Void sticker will void the warranty of your device!
• NOTE: Some versions of that console maybe don't have the sticker or it's relocated.

Step 4

• Remove the covers by using either a Spudger, Opening Picks or your fingernail.

Step 5

• Remove the six Phillips #1 screws with a screwdriver.
• The screws on the right are a bit deeper inside the shell as like the rest but are the same size.

Step 6

• Separate the clips at the front and the overhanging side from their mounting using a Prying Tool.
• Separate the two halves.

Step 7 :: Connecting the open console to a power supply

• Now that the console is open, connect it to the power supply.

Step 8 :: Turning on the console

• Put in a CD/DVD and turn on the console.

Step 9 :: Checking the Drive

• With a plastic tool, lightly press down these two levers at the same time. Ideally, the CD should now start to spin.
• If it doesn't spin, the whole drive or other parts of it may be damaged and need to be replaced.
• Don't forget to unplug the power supply again!

Step 10 :: Disconnecting the drive part 1

• Now, there are 3 flat cables to disconnect. Caution: Some have a small clamp that must first be released, so that you can carefully pull them out.
• Cable 1 can easily be pulled out. However, be careful not to damage it!

Step 11 :: Disconnecting the drive part 2

• Cable 2 on the other hand, has a clamp. This must be carefully preyed up from both sides before you can disconnect the cable.
• Cable 3 can easily be pulled out.

Step 12 :: Unscrewing the Drive

• Now the drive, which is held in place by 3 screws, can be unscrewed.
• Caution: It's still held on the underside by a flat cable! It's the cable for the laser head.
• This cable also has a clamp that you can carefully pry open and release the cable from the interface.

Step 13 :: Unscrewing the drive

• To release the laser unit from the bracket you must remove the 3 marked screws.
• Attention: Don't loose the small brackets and screws!

Step 14 :: Removing the Laser Unit

• Now you can remove the rail from the laser unit, which it moves on while it reads the CD.

Step 15 :: New laser preparation / desoldering tin

• The new laser must be prepared. The small portion of solder at the area marked in green, must be removed with the help of desoldering wire. At this point, the new laser should look exactly like the old one.
• Take the desoldering wire and the heated soldering iron in-hand, and remove the bit of solder from this part.
• Finished! The new laser is ready to be installed! You're almost done! Now you just have to screw everything back together again in reverse order!

Conclusion

Follow the steps in reverse to reassemble your device.
