My 47ga6400 has started to go into the home screen on its own. No matter what hdmi input i use it keeps going into the home screen. If i try to watch tv it will be fine for about 2 to 5 seconds and go to the home screen, if i try another input, like my ps3 or xbox it does the same. Also it does not want to play any movies no matter what media player i try. Ive tried everything including factory resets and nothing fixes the problems. Can anyone help? Thanks guys!
