If you’re having difficulty getting your TV screen to display anything but a black screen, it’s important to work out if the TV is switched on and just displaying a black screen, or if the TV isn’t powered on at all. The first thing that you should look for is the standby light, this can usually be found on the lower middle or lower right of your TV. The standby light will be lit when your TV is turned off and unlit when it is turned on.
