I recently bought the new Wind Waker Wii U bundle and it has been working great since last Friday but I just recently finished playing Wind Waker HD, saved, and shut down the system. I then opened the TV menu to change input on my TV and the gamepad's screen just came up black with faint grayish squares. I immediately panicked. I turned the system back on and my fears were confirmed. The gamepad screen isn't displaying anything on its screen other than 99% black coverage in the form of many black lines. The console itself seems to be working fine as it shows the Nintendo Network login just fine. I can't login to my Wii U as of now because I can't see the gamepad's input to enter my password. I tried removing the battery for a couple of minutes and then reinstalling it but that did nothing. The touchscreen still seems responsive to touch but it just isn't showing an image like it's supposed to.
It's just strange how it was working perfectly and then I turned it off and now it's not showing anything. If I were required to send the gamepad in, would I need to remove the clear skin that I installed on the gamepad hardware? There isn't any screen protectors on the screen but I did put a clear skin on the hardware to keep it from getting scratched.
Here's a picture of the screen with the TV Control open (with the console turned off):
