Just replaced the housing on my PSP 2000 (Daxter Ice Silver Edition). Everything went good, the only thing I didn't put on the housing is the umd. PSP turns on, but screen is blank, no light no nothing. I figured it was showing me the set date screen, so when I clicked O, it made noises so I know that I'm not bricked. I was able to scroll like I was in the XMB, so again I'm not bricked. I reinstalled the screen ribbon cables twice, and still doesn't turn on. Could I have messed up the cables without any visible damage?
