My daughter put a paper card in the disc slot so i took apart the ps3 to get it out. One of the white rollers to take the disc in seems to be missing so it won't load discs. I also vacuumed the dust while it was open. Now it will play movies that are already downloaded but when i try to open Netflix or playstation store the screen just turns black and i have to turn it off from the console. Did i kill it? Anyone have thoughts?
