Cleaning the laser lens on a PS2

Why do this?

If you find that disks don’t load properly (you get "Disk Read Error"), or some disks load but others don’t, it may be that there has been a build-up of dust on the laser lens. This can best be removed by disassembling the unit and carefully cleaning the lens. This is a repair you can easily do yourself by following this step-by-step guide.

 Note: This procedure involves removing the PS2 cover. This will invalidate the warranty. A tell-tale sticker will show the cover has been removed.

Step 1 – Try a quick check to see if the laser is dirty.

You may find that by opening the disk drawer and blowing hard into the player that you can dislodge some dust. If after doing this you find that the disk now works, the lens probably needs cleaning.

Step 2 – Assemble the tools you’ll need.

To perform this your’re going to need to remove the PS2 covers and clean the laser lens. For this you’ll need:

  • Cross-point screwdriver (large)
  • Small flat blade screwdriver
  • Watchmaker’s crosspoint screwdriver (small)
  • Isopropal alcohol (Isopropanol or Ethanol – similar to Methylated spirits). Available from Maplin
  • Cotton buds
  • Magnifier (optional)

Step 3 – Remove the screw covers

The PS2 has two types of screw covers. Four rubberised covers -  which also act as feet - and four plastic covers. Carefully prise out the covers with a flat bladed screwdriver.

Step 4 – Remove the screws

Remove the eight crosspoint screws. The four on the left of the photo are quite long.

Step 5 – Remove the main cover.

Turn the unit the right way up and have the rear panel facing you. Carefully peel back the tell-tale label that is fitted across the upper and lower covers. Once you peel back this label, a ‘warranty void’ symbol will appear on the label.

 

Carefully manoeuvre the cover over the front connectors and hinge it over to one side. You will need to hinge it as there is a flexible pcb linking to the front panel indicators and switches. See larger version of ‘Remove disk cover’ picture.

Step 6 – Remove the disk cover.

With the main cover out of the way, use the watchmakers crosspoint screwdriver to remove the four self-tap screws. Then remove the disk cover.

Step 7 – Clean the laser lens

Have a look at the lens first through the magnifier. You can easily see if it’s dust-covered.

Using a clean cotton bud, dip it in the isopropanol and gently wipe the lens in one smooth sweeping and twisting movement. Inspect the lens again with the magnifier. It should appear completely clean.

Step 8 – Re-assemble

Re-assembly is the reversal of the above..

Step 9 – Test

Re-connect the PS2 and test, preferably with a disk that previously did not read reliably.

Other PS2 problems

PS2 Freezes:

My experience is that normally reliable systems randomly freezing (locking up) can sometimes be due to overheating. Check that ventilation slots are clear and any fans are operational. As a diagnostic, try positioning a ventilation fan next to the unit to see if it helps.

PS2 won't read disks:

This happened to my son's unit. Having confirmed the laser was clean (see above) ,I speculated that the sled that carries the read head assembly was not moving on its runners correctly. As a test I tried tilting the unit forward (by raising the back of the unit) so that gravity assisted the sled . Hey Presto! It started working again!. So then it was just a matter of dissasembling the unit and carefully cleaning the runners.. It's been working fine since.
