After replacing the deck and Laser with a brand new one my PS3 still won't read games or Blu-rays. I makes like a clicking sound when trying to read. But, it sounds like it trying to read them. And The game is brand new no scratches on it.
i'd send a pm to barrybarryk and ask for his advice. and include a link to this thread for him also. i know he has been back on lately so you may be in luck. he seems to have vast knowledge of these types of problems.
