I am having a problem with the mag254. It was freezing a little. Changed my DNS to 8.8.8.8 and that helped. But my problem is that the screen just goes blank. Black. For 2 or 3 seconds. It will do this not only when I am watching a movie but also on the home screen. I have been using it for over 2 weeks and watched a few movies on it. Not a problem up until today. Any suggestions
