Instructions
Turn on the Sony PS3 by pressing the "Power" button on the right of the console. Pressing the "PS" button on the controller will not work as the controller is not synced properly.
Connect the mini USB cable end to the USB port on the Sony PS3 controller that is not syncing with the PS3.
Connect the other end of the mini USB cable into one of the Sony PS3 USB ports. Leave it in for no less than five seconds.
Pull the USB cable out of the PS3 controller and the lights will stop blinking. The PS3 controller is now re-synced to the PS3.
