So, this is the problem: I've agreed to fix a PSP that had been dropped and hit the ground. Screen works A ok, and buttons respond as well as used buttons ever will =) The only problem is that it wont charge or work with a battery in it. When I use an AC adapter it works flawlessly, but as stated, when a battery is inserted it won't charge, or run without AC adapter. I've measured the connections between the charger contacts and the battery contacts, and everything is connected ok, so what I'm wondering is if there's something anyone can say that I've probably missed. Thanks in advance!
