As the title says, I'm battling with a CD player (Sony CDP-N550C) that's randomly skipping. I already replaced all the buttons in the entire system (before I got the complaint about skipping, the system was basically unusable at that point). While investigating the skipping I found the plastic pickup guide (it only has one metal rail) was broken in several places, so I fabricated a new guide out of metal. The guide is completely flat, the same height and it's been lubricated. I even tried a new pickup, but it still skips. Sometimes it'll skip a couple seconds, other times it'll skip to the end of the next song, or even several songs at a time. The skipping is also completely random, and it doesn't matter what CDs are used.
Can any of you think of another reason why it would do this? My aunt doesn't want to move away from physical CDs, and she doesn't have the money to buy a new changer.
