I am having a problem with my Sony PSP.  I dropped my PSP and the
little power switch broke off.  I had to buy a new power circuit board
and take my PSP apart and install this board.  Everything works fine
now except I cannot press my D-pad to the right.  I don't know what I
can do to solve this.

D-pad problems are common on the PSP, you could try the new D-pad that
Capcom has released that comes with their new Street Fighter (should
be released Feb 06). But better, try cutting up a piece of cardboard
and put that between the right button of the d-pad and the little
rubber piece holding attaching to the d-pad.

The rubber piece is not seated properly. Open the PSP up again and
make sure the right direction is seated the same as the other three.
Be careful, as the right direction is very close to the screen, and a
improper solution to this problem may harm your screen.

I have opened it and reseated it many times  but it just does not respond
