I got one of these almost two years ago and its worked pretty well. Tonight it decided to display a solid black box on my TV, as if it were a display screen since it is about 1/3 the size of my TV screen. It goes off and on, but is mostly on. My guess is something in the electronics is heating up or there is a component of some sort breaking down.

I called directv but you know how hard it is go get a person. Not sure if they even have any.

Anyone have some ideas on what it is or is it fixable>?
Thanks
