Problems! First Build

Hi, I recently finished building my first new computer, but unfortunately when I boot up the computer, I only get a blank screen. On boot up, all my fans spin and all the lights are lit up. I have a Z68 mother board and from what I have researched it will not test beep.

I am however using a Samsung TV as a temporary monitor until my ASUS monitor arrives. The Samsung TV is plugged into my desktop through a PC monitor cable and the TV detects the signal but the screen is blank.

Please, can anyone help me figure out why there is nothing on my screen? Thank you :]
