Change your Ps3 lens KES-400AAA and KES-410A or KES-410ACA
Side by side, here are the PS3 lenses that are currently available for your PS3. If you ever decide to change the lens yourself, my best advice is to always open your PS3 first before ordering any new lens as there is no way to determine which model use which lens.
Attention: PS3 40gb may use a different lens: LENS KES-410A or KES-410ACA (but some ps3 40gb has been found with the other lens KES-400AAA)
