I don't know what I'm doing wrong. It worked on my old Wii U that I sent in for repairs, now Nintendo sent me the new one it won't work on my TV even though my TV is on the manufacturer list. Don't know what gives.

Sometimes mine doesn't work when I want it to. Then later it's A okay.

Maybe wait and see if it works later.

Make sure you point the GamePad at the TV. I know with our GamePad it needs to be facing the TV (like a remote), and doesn't register if I'm lounged sideways on the couch.
