    • Before starting, make sure you have a die cast laser. Plastic lasers are not repairable.

    • If your laser is plastic: You must replace the laser due to uneven wear.

    • If you have a Die cast laser, this fix may improve the read rate. However, this is an age based failure. Note: In some cases, the laser resistance will need to be adjusted.

    • With the laser removed from the system, remove the 2 Phillips PH1 screws. Check if the laser is plastic.

    • If the laser is plastic, it cannot be repaired and must be replaced. The example shown can be adjusted.

    • Only adjust it enough to reliably read games and music CDs again. If the speed is too slow, the laser can physically "burn" your games or kill the laser.

    • Consider anything less then a 80-90% read rate a failure. These are hard to reliably recover.

    • Before starting, mark the original adjustment point and write down the factory setting as tested. It will be difficult to take it back to stock without this information.

    • Adjust the trimpot incrementally using a Phillips PH1 or other compatible bit. Do this until the laser is reading games more consistently.

    • If possible, test on a known good system first.

    • Improving the read percentage: If you are not happy with the results, keep adjusting the motor. Repeat until you are happy with the passing read rate, or the motor doesn't spin.

    • If you see the Insert PlayStation CD-ROM screen, the motor is running slow. Adjust the speed to be faster.

    • Partially reassemble the system and test it. If it is sufficient, reassemble the system.

    • To test the read percentage, get a few known good games and see which ones load. A minimum of 5 test games is recommended. Only adjust the laser again after each full test is done.

    • If the game loads, test play the system for a few minutes to check the stability. Important: Some early revisions have FMV issues - THIS IS EXPECTED.

Do you have the specifics as to the spacers and trimpot adjustment when using a new KSM-440BAM (with extension cable if needed) on either SCPH-1001 or SCPH-5501?

Leif Behrmann - Contestar

No - I do not.

Nick -

Hello, I recently attempted to replace my weak laser in my 5501 with a 440BAM and it did not work, I even tried putting back the old laser but it wouldn't work again at all no motor spin or anything. Any ideas as to what I'm doing wrong or how to fix? Thanks!
