Chromecast Just Shows A Black Screen

At first Chromecast shows the logo, but when I cast something, it just shows a black screen. To fix Chromecast and stop it showing a black screen, hold down the button on the Google Chromecast (next to the wire sticking out the end of the Chromecast) until the light at the end goes solid white. Then setup your Google Chromecast again. This should fix the issue of it just showing a black screen.
