Hello, My psp's screen was broken, so I had to change it. I took a replacement screen from my cousin's PSP. The screen worked good on his device but when I connected it to my device, problems started arising. First of all the psp didn't turn on (not charging either) so I had figured out the issue was from the battery, I replaced the battery. The psp did charge but the screen wasn't working. I thought I didn't connect the wires correctly, so when I unscrewed it's cover and put it back, it stopped charging. It doesn't charge anymore neither does it turn on (I presume its because the battery is empty). I checked all the wires, battery wires and everything but it doesn't charge. Anything I can do ?
