I dont think your skipping problem is being caused by a faulty laser assembly or a bad spindle motor not ramping up to the proper speed
If either of these components were bad, you would get a DISC ERROR or NO DISC message in the display window because the disc couldnt be read
You may have a simple fix .... I'll bet the factory lubricant on the rails that the laser sled rides on, has dried up, and is causing the laser sled to momentarily bind or stall when the sled comes in contact with it instead of moving freely along it's pathway.
When the laser binds and/or stops momentarily ... it loses lock with the flags on spinning discs data stream and it's ability to read the disc and skips
It will skip until it can move past the dried lubricant spot and re-locks and reads the data stream again
Because your player is playing fine except for some momentary skipping .. I think the Laser and Spindle Motor are OK and that the dried up lubricant is stalling the laser sled causing it to lose lock and skip
Try cleaning and lubing up the rails that the laser sled rides on, and I'll bet that solves your problem
