Analog nub problems? Here is a quick fix!
Is your analog stick moving up and to the left on its own?
The problem is the screw right behind the analog nub tighten it up but not to tight you will break it.
Don't have a screwdriver handy or the screw wont tighten all the way.
take some black tape (now you just need about a 1/4 of an inch) stick the narrow part on the faceplate right below the LAN switch and stretch it across tightly and stick it. Now if you did it right you should have missed the LAN switch and the memory stick cover.
I came to this conclusion after I started having problems with my analog.
God did I search Google for months and believe it or not it's a common problem that people don't know how to fix. So after trial and error I finally figured it out.
The following screws affect the analog nub the one I mentioned above. The top screw on the back top left and the one on the bottom of the face plate.
Hope this helps people out!
If I missed anything please don't flame just politely let me know.
Or you can just replace the faceplate.
