ok so about 2 weeks ago i had bought a psp off a friend because he thought that it was broken and the screen had cracked(turns out it was only the faceplate and it did work). so i ordered a replacement faceplate, carefully put it on and had a brand new psp for 50 dollars. Everything was fine until today. I tried turning it on earlier and it wouldnt power on. The little green light went on and the backlight went on but it would shut off like 15 secs later. Is it bricked or sumthin cuz exactly seen what a brick does and ne help or explanation would be appreciated.
