Plug in the TV to the mains and use the power on button to turn on the TV.

despite the aweful TV image shown here , that came up as I turned on the TV onto youtube. This happeded to be a random image and the TV was perfectly fine. The images I was going to put up are not working.

So at this point, you should see the screen not looking blue and cloudy like the second image and after entering the sources tab. and openimg say youtube. Which is where this first image came from and had me worried for a moment that I had damaged the screen. If it's all ok from this point. Once again unplug the TV. Then flip onto back.
