Edit 2: Might as well use this accidental post for something.
My PS3 won't read XCOM: Enemy Unknown right now. I know there is something wrong with the disc drive already. I have to lift it vertically for it to read any disc at all. Otherwise, there's a clicking sound. I'm 99% certain it's a loose gear inside the blu-ray drive. Lifting has worked for over a year now, but it's fairly annoying. Now I'm wondering how long it will be before it stops reading all discs. It has trouble with certain games, like XCOM: Enemy Unknown, Demon's Souls and the Sly Collection but works fine with everything else, as long as I lift it. Am I probably correct in assuming that it's a loose gear and not something else? How hard would it be to fix it myself, considering I have very little experience fiddling with mechanical stuff?
