amybody good with fixin disc drives? (ps3)

[RATS]

i traded my ca sportline p90 for a worked on ps3. all was well then i accidentally powered off the system by unpluggin it, and now the disc drive wont pull in or eject discs. i have looked inside, and went by youtube's videos, which are useles thus far. it will still read discs if i manually put them in, but if i cant fix it by this weekend its goin back to the guy, and im gettin his bolt action and guille suit. (no loss there imo) but if any help can come in before then, i will gladly buy mk9 >:D
thanks all

ps i have absolutely NO experience in fixin game systems. i dont even know what system i have beyon a ps3 lol
