I've heard loads of people having the same problem but so far no answer!
Some wii U are coming with this problem that the T.V doesn't show ANY image at all , so you can't Sync the gamepad with the console since you can't see any symbols at the T.V . The console turns on normally the gamepad too , everything is correct , follow the instruction on the manual step by step ,you try different T.Vs different HDMI cable , try the AV cable but no success ..
So the final solution is to send it back to nintendo to get a new one...
But what if you want to try to fix it by your self?
Can someone please solve the mistery of the bricked wii U's?
