Toshiba 50l711u18 TV Permanent Black Screen

Hello, my Toshiba TV worked fine until today. When I try to turn it on the screen doesn't display. It's a permanent black screen with no display. However I can still connect through Chromecast and play music, but still no display. I tried turning it off and on, leaving it unplugged for an hour, and changing the plug to no avail. There is no weird smell or sound coming from the TV. Any ideas on how I can fix this?
