i just got the psp repaired after i bricked it. they told me that they had to change some parts. well after two weeks i switched the psp on and the screen seemed like it was cracked with black and white stripes down the middle and a thick blue line down the right hand side. in the bottem left you can see a bit of the screen and the rest is black. does anyone know what the problem is? my warrenty on my psp is running out fast!
