Serious Analog Stick Problems

[Jimsocom]

I've been experiencing a problem with my PSP 1000's analog stick for quite awhile now. The problem is that everywhere in the 90 degree area from the left to the up of my analog stick is very unresponsive, meaning my character in a game will move at a an increadibly slow speed even when I push the stick in that direction all the way. In the middle of that unresponsive spot, and down in the middle of the bottom and right, I have dead spots, meaning when I push in that certain direction my character will cease movement entirely. The unresponsive parts, but not the dead spots, go away for about 30 minutes if I remove and put the faceplate back on, but then they come right back.
I can't fathom what the cause of this problem might be, and I've been looking everywhere for a solution, I'll give you a list of things I've tried:
-Replacing my analog stick (Not just the nub, the actually stick under the faceplate)
-Using a stock faceplate with a different buttons
-Using stock buttons with a different faceplate
-Using a different faceplate and it's corresponding buttons
-Installing JoySens
-Blowing into my analog stick
-Cleaning off the connections on my stick and the circuit board inside the PSP
-Replacing the rubber block under the stick
-Different looseness/tightness of the faceplate

I've tried everything, but nothing is working, my faceplate is screwed in as securely as I can get it, but my stick just won't work, can somebody please help me? Thank you for reading.

i'm not sure.may be due to the part of board that relating with analog stick.

Did you buy a new faceplate? Tighness isn't the only factor.

Why don't you solder the board to the stick?
It looks really easy, fat pads, even a monkey could do it
