Sky q box keeps turning off and remains unresponsive. Eventually I give up and switch it off at the wall. When I turn on again the blue screen with the message saying press home when the screen goes blank comes up, the screen then either goes blank or 'snows out' so the message is barely readable. If I press the home button nothing happens and the box continues to rumble. Once in a while The home page does appear only to disappear a minute or two later. Do I need a new box or is there a fix?
