i foned sony custermer service thy said you have 2 send it in for a repair on the lens because the lens is broken which will cost you about £100 atleast. also i searched online and it said buy a new ps3 lens and open your ps3 and fit it yourself its cheaper but you have to handle all the parts on the inside of your ps3.
