When I turn off my tv and set top box (Foxtel) after a while the tv restarts itself and looks for a signal. That’s when the horrible screen saver images start up. They will rotate for hours until someone turns on the set tops box to watch the tv. Now I find these images are BURNING IN to the TV. I can see in blue coloured vision the mountains burnt into the background. I cannot turn the TV off in a way to prevent the tv restarting and showing the screensavers photos. Please help me.
