Clean the CD laser in the PlayStation 1
The PlayStation 1 runs on CD-ROMs. After thirty years, dust accumulates on the laser — and the console starts stuttering, crashing or not recognising discs at all. Cleaning is the easiest first step you should take.
What you need {#what-you-need}
- Phillips screwdriver (PH1 and PH2) — for opening the housing
- Isopropyl alcohol (minimum 90%) — for cleaning
- Lint-free cotton swabs — for the lens
Unplug the console before you start. The PS1 has a fairly accessible motherboard — safety first.
Step by step
1. Open the PS1
Remove the screws on the bottom. Some screws are also hidden under the rubber feet — remove these carefully (they’re reusable).
Carefully lift off the top housing.
2. Locate the laser
You can see the CD tray and directly below it the laser sled. The laser sits centrally on the sliding sled.
3. Clean the lens
Dip a lint-free cotton swab in isopropyl alcohol and gently rub in small circles over the laser lens. Use minimal pressure — the lens is delicate.
Let it dry completely (30 seconds).
4. Close the housing and test
Reassemble the console, insert a disc and test. In most cases cleaning fixes the problem.
What if it still doesn’t work after cleaning?
- Adjust the laser potentiometer — A small screw on the laser sled can increase laser power. This is a precise job — look for a video tutorial for your specific PS1 model
- Replace the laser — If adjustment doesn’t help either, the laser is worn out. Replacement costs €10–€20 and is very doable
Does your PS1 work consistently better when you lay it on its side or upside down? Then the laser is nearly finished. It's a known workaround, but not a permanent solution.
