I just opened my Nintendo refurbished Wii U, and everything was cool until I noticed that my gamepad screen jumps/flashes/flickers every 2 seconds or so (like the screen is split for a quarter of a second).
I haven't been able to find any posts with that problem yet. There are no running lines, half the screen isn't cut off or anything like that. It just... seizures for a split second. I will call support after Christmas, but I couldn't start a repair because I couldn't find the problem on the support website.
Any help is appreciated, but I'm certain I'll have to send it back. Thanks!
