D-pad buttons not functioning
Checked the ribbon. Looks lite it is connected. After testing the joystick and d-pad i found that left-right does not work at all on either. seems lik I can get a response from the left d-pad button if i press really hard on it, but it is intermittent. Wondering if the problem is with the psp?
Sounds like you might have the joystick wired up incorrectly or incompletely. The joystick is connected to the D-pad controls, so it will cause the buttons to work intermittently when it's not wired up.
It's also possible that the D-Pad is positioned underneath the LCD bracket, keeping the buttons from contacting. This one is less likely to be the cause.
I'm happy to look at the joystick wiring if you want to post a pic.
