Wii U black screen and gamepad not connecting

Hello,

I was trying to go to the eShop to buy some games before the eShop shutdown. Before it launches, a system update is required. So I did the system update and was provided a error message. I don't recall the full details of the error message but to summarize, the update got interrupted somehow and it turn itself off. Now, whenever I power on the system, I am greeted with no Wii U logo screen and "no signal" screen from my TV. Essential a black screen. My gamepad is also having a "unable to connect to Wii u console" error message even though my gamepad is close to the console. I tried to sync my gamepad to my Wii u console but I need the tv screen to sync it. I feel this a software issue and not a hardware issue. Something is preventing HDMI from activating Im guessing. Is there any way of fixing this issue?

Ill try and elaborate more if anyone can reply to this!
