When I initially got my 50in display, I found that I had to leave it on 
all the time to avoid the system freaking out, but that hasn't been the 
case for over a year.  I now setthe  GPU to shut off the display which 
doesn't actually shut off the display, but I have the TV set to shut off 
after a certain amount of time with no input.
I do have to turn it on my hand whenever I want to use the computer, but 
it's quick to power up and really hasn't been a big deal ever since they 
fixed the issues with the system freaking out because of a lack of displays.

There is also the possibility to use a USB to CEC adapter to shut down 
and wake up your TV.

I picked one of them up and got it to turn on and off the TV from a 
script, but I haven't been able to locate how to hook it into the power 
management properly to get things automated.
