2 days ago my phat CFW 5.50 GEN-B PSP suddenly decided to give me a black screen when I turn the power on. Prior to that I did not touch the firmware for over 3 months. I could not access the recovery mode and unlike most other full/semi bricks i read about, the green light stays on and doesn't go off on its own. I don't think the screen itself is busted as I get no sound after I turn on the PSP normally. I borrowed a pandora battery and a magic memory stick from a friend and gave it a shot, but all I get is the green light, ms access light and the wifi light and I still have a black screen. I'm not really new to using these hacks but I seem to be running out of ideas. Any advice would be much appreciated.
