Well maybe I should have asked this a long time ago because if it's dangerous it's already had its effect on me!! well about a year ago I tried to open my psp to fix the analogue stick (and well I didn't manage to do anything useful for the analogue) and when I was trying to put the psp back together I accidentally put the screw underneath it in the back screw hole and since I thought that it was the right screw I stupidly screwed it so hard that I broke my lcd from the inside and I've been using it like this for about a year now I wanted to see if it's dangerous and that is it worth buying a new on! cause my psp is nearly 3 years old now!
