Logitech wireless action controllers for ps2 are arguably the best wireless controller for the ps2.  However, their major flaw seems to be that the x button tends to stick after some use.  This happens for one of 2 reasons:

•             1.  The x button is dirty and needs to be cleaned.

            - or - (and more often)

•             2.  The silicon (I think it is silicon) connector that acts as a spring for the x button breaks down over time.

The x button is usually the only one to stick.  This is because the x button is used the most.  I have come up with a very easy and quick fix for this problem.

Please note that if your controller was bought under a year ago, you can call Logitech and they will send you a brand new controller.  But if you get that new controller, and you do this fix on your old controller, you will have 2 working Logitech controllers.  Logitech has had so many of these x buttons stick that they only need phone conformation of the serial number (if the serial number indicates that the controller is not yet a year old) in order to send you a new controller.  They will not take your old controller (to my knowledge).  However, Logitech has excellent customer service and I do not advocate ripping them off.  They do a pretty good job so cut them a break and do not exploit this loophole that I've conveniently pointed out.

Anyway here's how to fix your sticky x button.

Step 1.  Take off the battery cover, take out the batteries, and unscrew all the screws from the back of the controller.

Step 2.  Remove the back of the controller.  Note that this can seem tricky because it appears as if the shoulder buttons are attached to the back and front by a short cord.  However, they slide out of the back of the controller quite easily.

Step 3.  Remove the 2 screws from the circuit board.

Step 4.  Carefully pull the circuit board away from the front of the controller.  It may be difficult but don’t worry, the circuit board is pretty durable.

Step 5.  Remove the blue silicon piece from the right side of the circuit board.  It is attached via 4 plugs.  It should come off the circuit board when pulled.

Step 6.  Flip the piece 180 degrees (or whatever you choose) so that the part of the piece that was for the x button is now for the triangle button (or another button if you so choose).  I chose the triangle button because it is used less than the x button and is easier to deal with than a sticky x button (and actually now my triangle button doesn’t stick, it is just noticeably less springy than the rest of the buttons).  Then reattach the piece to the controller.  You will have to pull the plugs back through the holes in the circuit board.  Use your fingernails or needle nose pliers for this.

Step 7.  Trim the top of the piece so that it is flush with the top of the circuit board.  Be careful not to cut too much.

Step 8.  Put the controller back together.

Step 9.  Play games with the controller.
