Hello htcthelegend,
As a measure of troubleshooting, have you tried connecting the computer to any other display, or was it only connected to the television?
I know I always check the easy (physical) things first... (i.e. cables are all firmly attached, from video card to display, the display device is on the correct HDMI input, both the computer and display are firmly connected to a power source, etc).
Once you rule out all of the physical aspects, then you move to hardware and software issues.
