i just got a xbox 360 with rod. wing i press the power button i can hear the cooler spinning but there's no light. i opened the system and i sow that the power switch was replaced. the swich has 4 pins: 1 2 3 4 the pad on pin 3 is missing, so the pin is unconnected. is it possible that because pin 3 is missing the leds aren't working?
