OK I am having trouble with the PSP screws. I am trying to repair a broken screen but I can't even get the screws off. A couple of months ago I had this same problem and instead of using a 1.4mm screwdriver like the manual said I used a 2.4mm screwdriver and it got the screws out. Now I have tried using all screw sizes on a different PSP and I cannot get one of the screws. I am letting some WD-40 sit on it right now but I don't think that will do much. Are there any suggestions or past experiences that could help me out?
