Need some help from people who know vidya repair. My PSP 1000 is in great shape except right dpad is sometimes unresponsive. I already took it apart and cleaned everything (the contacts, the pad, readjusted the thing to boot.) It feels a little better but when scrolling on the XMB, for example, it still drops maybe one in five inputs, or holding it will just eventually stop responding and I have to depress it again

Is there anything else I can try or is it likely just borked?
