well, you have to buy a new screen. i did the same thing and all i had to do was take the face plate off, diconect the screen from the motherboard, pop the sreen out of the psp GENTALLY, then you just have to get a new screen, you can buy one on amazon.com for about $45.00 Dollars(thats how much mine cost). then put it all back togather in the reverse order.
