Basically all you want to do is go over to the TV power button that's on the TV and after turning it off using the button turn it back on but instead of releasing hold down that button after about thirty seconds the TV should turn back on again this is only if you're having the same problem as me which is where your TV has gone black but your power light is green and flickering or just staying solid otherwise I guess try the other methods that have been given to you but other people on this website
