I have a psp phat and I have a Pandoras battery and Magic Memory Stick and never had to open up my psp. recently the d-pad of my psp hasn't been working properly. Like when i push the down arrow it goes to the left, the right arrow takes a little more pressure to work, and only twice now it went up when i pushed the right arrow. Is there any way to fix this? I haven't yet opened my psp to check the d-pad but i am going to very soon. (I haven't opened it yet cause i need my friends tiny screwdriver) What should i try to do to fix this?
