Hook Up External Hard Drive To Sony Tv Sony Vaio Turns On But Has Black Screen.?

Sony vaio turns on but has black screen.? - hook up external hard drive to sony tv

I have a Sony VAIO PCG-grv680 whenever she is on the screen is blank, and when I did not go off without me to take the battery. It is also missing the hard drive.
I have tried to an external monitor by pressing all the buttons to connect any luck in touch.
