Nevermind guys,found the problem. I was using a Hdmi switcher and for some reason it wouldn't work. I unplugged my XB1 and put the wii u into that slot and is working again
It froze and so I had to pull the plug. Don't understand why this happened because it was just working fine last night. The Gamepad is still working with the console though,just can't see anything on the TV.
