The optical unit has laché my ps3. I order a new optical block, and surprise: The optical unit received is not an original block, but more importantly, is not new (traces of oxidation on some metal parts). Of course after assembly a little test with my ps3. I had fears, and they were justified. The "new" block mounted, allows my ps3 play dvd but Blu-ray, so more games. I sent an email to the seller, and I expected either a refund or an exchange with a new, or at least tested and working.
