Black screen but can see display with flashlight

[Nailles]

When I start my computer its screen remains black. I have it connected to a TV through HDMI and the computer is fully operational. When I shine a flashlight on the computer screen I can see the display, identical to what is on the TV. Does this mean screen replacement, cable replacement, or is there some adjustment within the computer to bring screen brightness back up to normal? Thanks.
