My 15"MBPr goes dead when I plug in a TV over HDMI

Question

I have a 2014 15"MBPr. It is the version with the 750M. All firmware and software is up to date, all the cabling has been verified to be working.
I use this laptop at a desk my lot. Until recently, my setup was a 24inch AOC display connected through an apple mini display to HDMI adapter. I leave the laptop screen open and run both. This has worked fine since I've had the computer. I have lots of other peripherals plugged in too these are as follows.
Thunderbolt to Ethernet (meaning both thunderbolt ports are occupied. Wifi is not an option)
USB3 Hub, which has my keyboard (A DAS Model S), my mouse (a Logitech Performance MX), my 3TB western Digital drive, and my focusrite scarlet USB audio.
Recently, I bought a TV. It is a 42 inch Vizio, model number M422i-b1. I went and bought an HDMI cable so that I could use it as a display if I wanted to. I plugged the HDMI in to the TV on one end, and then in to the HDMI port on my mac on the other end. It worked fine, I set up the displays so they weren't all mirrored, and so they were arranged in the right way.
I used the setup like this for an hour or two, then disconnected the laptop to take somewhere.
I came back a couple hours later, and reconnected the computer in the same manner that I described above:
Ethernet to one thunderbolt port
Display out to my AOC monitor on the other
USB out to all the other things
Power in via magsafe
After connecting it all up I tried to wake the computer, and nothing happened. The backlit keyboard came up, but all three screens stayed black. It seemed like the two external displays were getting a signal, but the signal was a black screen. Both external displays (The AOC and the Vizio TV) usually will say "No Signal" If they are not getting anything, but they were not saying "No Signal"
- I tried a restart of the computer, nothing. All screens stayed black but I did hear a startup chime as usual. The grey screen and apple logo came up, but after that was finished loading all screens went black.
- I tried connecting the displays after the laptop was up and running, I did the monitor first via thunderbolt and it worked fine, so I eliminated that as not being the problem. When I plugged the TV in via HDMI though, all the screens immediately went black.
- After force restarting the computer again, I tried plugging the HDMI in to a different HDMI plug on the TV. The same problem persists with all four HDMI plugs. Then I tried leaving the cable on on the TV and pluggign the HDMI in to the computer when there wasnt anywhere for the computer to output to. Even without the HDMI port I want to use on the TV selected as the one I want ot use, the computer immedeatly goes black when I plug in HDMI.
- Every time I force restart the computer, upon logging in (without the TV connected, computer will not even boot with TV connected) I recieve a message that says "Your computer shut down because of a problem, do you wish to continue?"
- I have tested all the inputs on the tv with other devices (A windows PC and a PS3) and they all work fine. In adition the HDMI cable I am using is good.
What should I do from here to fix the problem?
