My PSP Fat developed this strange problem after I switched out the standard black case for a clear one. When opening the UMD drive while the system is on, it cuts the power to the system. I can tell because the system shuts off immediately after opening the drive door, and if this is done while charging, going into the system menu shows that the PSP doesn't see the battery in the system, only an external power source (the charger.)
I have a strong feeling that it could be the metallic jacket within the UMD assembly is causing a short somewhere, but I've already tried readjusting the parts within the system to make sure.
I can't figure out what's wrong here. Anyone else run into this problem when doing a full case replacement?
