Few weeks ago i bought brand new PSP Slim Felicia blue. It's beautiful, but soon after Pandorizing it with 3.80 I discovered some problems: My power button sometimes doesn't work, sometimes when I want to turn it off green light stays for few minutes. Also sometimes it makes noises from UMD drive (I couldn't shut it off so I removed battery to reset it). Friend told me to change the region in Recovery menu to American, but Power light problems still exists. Any ideas how to fix it?
