Default [Q] Tab Pro 8.4 Hangs on Boot

When I turned on the tablet today, it hung and just went to a Samsung screen that gets dim and then bright every few minutes. It never boots.

I tried to boot to the recovery menu and wipe everything, and it still hangs. I tried to connect it to Kies and it never sees it. It makes noise when plugged in and looks like it is going to connect, but it doesn't. I have the Samsung drivers installed, rebooted the PC and have the firewall and the AV client turned off.

Any idea how to get it back up and running?

I am somewhat of a novice on Android devices, but I catch on quickly.
