i have a phat psp, the screen is black. if i power it on green light turns on for approx. 30 seconds then cuts off, if on charger orange light is constant. heres what i have tried, switched lcd with another psp, so i know that lcd on broken psp did work. also tried unbricking with rains mms, no luck. ive also switched batterys. i have no idea, maybe a simple problem not sure.
