Well my little 8 year old cousin was playing on my ps3 , and he got mad and then threw the controller to the ground, when it fell the R3 trigger was broken, so it's like it has no grip anymore, and it doesn't stays in its position, and now I can't play mw2 because my camera will be going on circles, anyone has an idea on how to fix this, without having to buy a new expensive ps3 controller? :S
God... now i tried opening the controller and one of the screws inside is broken and i cant take it out, i tried to force open it, and then the L1 trigger is off and i cant put it back because i need to open the damn controller to fix everything, and i cant because one screw is broken and i cant take it out

lol dude ur controllers screwed, just buy one of the cheap ones online.

well you could of fixed your controller but you've broken the screw now.. it's a waste of time trying to get a screw that will fit again, it's just a waste of time trying to fix it basically. If you don't want to but a new controller thats expensive, just get an unofficial controller until you have the money to buy the proper sony one again.
