It seems that I am having worse luck. I have gotten the black screen right off the hop. My U is flashing a blue light. After six hours, it has made no difference. And yes, the HDMI cable is hooked up, turned to the proper input, etc, etc. The gamepad just tells me to turn on my tv and change to proper input. I have yet to see any home screen or "System update required" on my tv. Really frustrating.
I've heard that the flashing blue light is an indicator that something is wrong and you should call Nintendo. I think you got a defective unit.
