Hello we had a Blu ray lens problem so we decided to replace it. After replacing it we hear a weird ticking sound. The guy replaced the lens again + drive. Same result. It didn't damage the cd at all. So it was all set. After playing 2 hours of a video game. It decided to break again. It didn't make any weird noise anymore but it doesn't read anything at all. Luckily we're allowed to replaced the lens again at Monday but if it breaks again we'll get the half of the price back. The question is what is causing the ticking noise after inserting a cd and why did it break again after replacing a new lens ( not used lens )? Do we really have to buy a new PS3 :l?
