Why my Wii U doesn't turn on, but red light is blinking?

I have tried everything ifixit recomends to fix this issue, but my Wii U isn't completely dead, a red light blinks and using the AC adapter reset procedure is a momentary fix until I wanna play the next day, and this issue happens again. Is a tedious work that you have to reset the adapter everytime you wanna play your favorite games. Do I have to replace the Wii U motherboard?
