Need help with my PSP

[Kerodas]

So I've had my psp for 10 years now and few days ago, my right d-pad button refused to work. So I need some help with it since I really love this thing.
Is there any way to fix it or remap the button to volume down?
Or maybe there is some online shop that sells details for psp?
Please, let me know.

Well, apparently the sensor chip behind the d-pad buttons is the problem, any way to fix this?
