Solder (I have 62/36/2 rosin-corse solder) Soldering iron 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 ...
Now you should be looking at something like this.
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
