Question about Sony PlayStation Portable (PSP) Console
Good day all
I recently ran into this same problem of a PSP joystick "jumping" or hopping around. Since I'm an electronics engineer I was determined to get to the bottom of this annoying problem, I read all the posts on the site and none helped, but the problem turned out to be much easier fixed than I first anticipated.
First of all I assume that you know how to take the PSP apart and take out the joystick module as well. The Joystick module connects to the PSP mainboard by means of 4 contacts, seperated by a spacer conductor that appears like a rectangular rubber, be careful not to lose this during the process.
Here is why the problem occurs, when you have a faulty joystick module, one or more of those 4 contacts don't connect to the main board anymore, so the when the PSP is trying to measure the resistance to determine the joystick position, it reads a varying value, i.e. the contact is floating.
This happens for mainly 2 reasons, dirt or a faulty module, as stated in the previous posts, the contacts could be dirty, but this can usually easy be seen, and this wasn't the problem in my case, I had a faulty module, but luckily all is not lost.
Here's how to fix a faulty module in most cases. Remove the joystick module from the PSP completely, put that little rectangular rubber on the 4 contacts (clear in my case) aside and keep it safe. There is metal clasp on the bottom of the module, you can simply pop it off with a screwdriver, by slightly bending the clasps on the side and taking it off. Now you should be able to see a VERY SIMPLE mini circuit board with tracks on, on the bottom of the module, you can indeed pop this off too. On this you will see tracks where the joystick sliders move. Put the circuit board aside too. Now look at the now completely open joystick module, you will see the two sliders each having a metal part, each of these metal parts has 2 very small contacts that run on the circuit board tracks that you just removed, most times these small contacts get bent inward and they can't make contact with the circuit board tracks anymore. Just bend them slightly outward again, so that when you put circuit board back, they touch the tracks on the board nicely. Put the circuit board back, it just slips back on, put the metal clasp back, put the rubber back in over 4 contacts on the module and voila, if all goes well you will have a nice working joystick module again. Put it back in the PSP and test it to see if it worked. In my case it worked 100% and saved me a few bucks. Hope this helps everyone. Let me know if it worked.

Remove faceplate...........take out the joy stick.......remove the metal clasp on the bottom of the joystick.........replace metal clasp.........play with the joystick untill it rotates smoothly.......you may have to be a little rough with it*............when it rotates smoothly replace it.......if you can not get it to rotate smoothly buy one off ebay for 10 bucks

Hi PDaddy, The Circuit board that is used for the D-pad may be dirty and erroneously giving your PSP a signal to move the cursor, I have seen this happen to a few PSP systems. open the cover again and take a pencil eraser and clean the round spots that are under the D-pad direction buttons.

I was having the same problem on my psp so I stripped another one down (just took the faceplate off) and noticed that there is a small rubber strip that sits under the thumb stick....this had gone missing so tried the one from the working psp and hey presto it worked.
So it might be a case of you need to replaec that small part which can be bought very cheaply (less than a £1 here in the UK)

I just replaced my PSP's joystick and decided to test it out before I put the faceplate back on (so that I wouldn't have to take out all the screws if it wasn't fitted in correctly etc.). However, I found that without screwing the faceplate into place, the joystick kept sending my position in random directions making it impossible to play with. By putting the faceplate on though with all screws in ploace, the problem was completely errased.

I know how to solve this so worry not! here's the solution:
1:your joystick may have a little part that is dismembered so buy a new one
2:ask for a assistant to open your psp to put the joystick properly
3:I have the same problem so here's what I do.
