Your PSP-3000’s face buttons stopped working because the button contact sheet is dirty, the ribbon cable is loose, or the button board has corrosion. The D-pad still works because it uses a different circuit. Cleaning the contacts or reseating the ribbon cable usually fixes the issue; replacing the button board is the next step and is cheap.

To add: here is a guide: PSP 300x Motherboard Replacement
Please check step 18 till 20 (they explain here how to replace the input board).
