Step 1: Materials
T9 torx wrench
Surface mount LED's (I got mine at http://secure.llamma.com/catalog/leds-surface-mount-leds-c-43_81_75.html?osCsid=2d3615c06494e624a15689f18e5ecf54 )
Magnifying glasses (not required but highly recommended)
Pliers or tweezers
Step 2: Taking Apart the Controller
Now that you have the battery pack out you should see something like this.
Use your T9 wrench and start to remove the screws. There are 7 screws in total. There is a hidden screw under the white barcode where the battery was. (WARNING!! Once you break the barcode you void the warranty)
It is handy to have a magnet to keep all your screws in one spot.
Step 3: Pry It apart
It makes it easier if you leave the motherboard in the lower half of the casing.
Step 4: Find the LEDs
See the tiny LED's? They are marked D20, D21, D22, and D23.
HINT: I would take off the joystick nobs otherwise you might accidentally melt them. I am speaking from experience.
Now comes the tricky part. Put your magnifying glasses on and get your soldering iron ready.
Now what you need to do here is quickly touch the soldering iron to one end of the LED. Only hold it there for about a second or two then quickly touch the other end of the LED. Keep alternating like this till it comes off. Repeat with the other LED's you want to remove.
You want to be careful taking the LED's off because you can ruin the board if you leave the soldering iron on the board
Step 5: Remove the LEDs
Make sure you have the polarities of the LED correctly lined up with the boards
polarity. Wherever you bought the LEDs should tell you which direction the
To determine the polarity of the controller is depends on your controller if you
have a CG board the negatives are at the tops and the positives are on the
bottoms. If you have a matrix board all the positives are top and negatives are
bottom this applies to all of them but the third player LED which has negative top
and positive bottom.
(NOTE: You should add some solder to your tip.) Using the pliers you can set the
new LED where the old one was and holding the LED down with the pliers solder
one end. Once that end is soldered you can set the pliers down and solder the
other end. To make sure it worked (if you left the motherboard in the back part of
the case) slip the battery back in and use the rubber pad to turn on the
controller. Just set the rubber pad like you would if you were putting it back
together and push down like you normally would. If it lights up, you were
successful. If not, try flipping the LED to get the correct polarity.
Step 6: Finished
Once you have the case snapped back together do a quick test to make sure the LEDs work. So if they all work go ahead and screw it together and now you are done.
