So when I turn on my Wii U, nothing happens on the tv. Also it can connect to the gamepad to power it on, but doesn't display anything to it. Instead the gamepad gives an error saying to power it off and on. The last thing that happened on the Wii U before this issue was me trying to play Breath of the Wild, but about 20 seconds after it booted it gave a usb error. I can tell the Wii U is on because the power light is blue and I hear disk activity.
