Philips CDM 12.1T Laser Sledge Replacement

This guide shows the replacement of the laser sledge in Philips CDM 12.1T CD mechanisms. It assumes that you have already cleaned the lens and done the necessary troubleshooting to rule out other errors (see this article for diagnosis with the Service Shell). If you only get dirty disc messages or experience stuttering audio/video from time to time, you can still follow the guide to clean and grease the mechanism.

For documentation, I replaced the laser sleds of two CDI450 players with unreliable or no disc recognition at all. I took different approaches to find the easiest replacement procedure, so don’t be surprised if you suddenly see pictures where things are in different places.

There was no common denominator to pin down the problem, as all the CD-i players they’ve used were of different revisions and generations.
