Has anyone had there HD tuner go bad on there 942? All of a sudden my HD tuner to set #1 went haywire the picture had horizontal green lines all over the place. Thought it was a bad connection and tried a new HDMI cable but this did'nt help, tried a new set of component cables and still have the bad picture, Now tuner #2 still has a good picture, running the wires through the composite outputs. Called Dish and they are going to sent out a replacement 942. Tried to get them to send me a VIP 622 but they said I should wait till April. or pay the $299.00. Thanks
