So, I bought a used ps3 that was in need of repair for 50$. Well, it works fine other than the sound. When it first boots up, sounds perfect. Then it slowly, progressively begins to crackle and pop, until at about 8 minutes it's nothing but the sound of frying bacon. I know the basics about computer internals, so I am pretty sure I can fix it, just I don't know whats wrong with it. Anyone have a suggestion? I'll upload some sound samples if anyone wants to hear it.
