Welp, the problem started from nowhere. but the issue is My ps3 seems to have a lot of difficulties on reading blurays. It's not impossible. But it's really really hard. The only way I get to recogize the disks is putting my PS3Slim on vertical stand. Insert a disc and then right after that put another disc, the second disc will get stuck. then using a little force I remove the second disc and voilá the disk is reading. I'ts really risky so I stoped playing my ps3 for a while. I'm thinking of doing some cleaning since I never opened up the ps3 to clean it. Might it help me with my reading issue?
