Then if you want, you can go ahead and open up your PS3 and examine your Blu-Ray drive and lens. I did this to mine and found out my laser had mysteriously been scratched during a MW2 session and ended up buying a replacement. If this happens to you and you do think about a replacement, make sure it is the correct laser (Dual vs. single lens, PS3 model and hard drive capacity, and shape of the laser)
