I just bought another tv today. All of my connections up until now have been component. I tried hooking this one up via HDMI using multiple h20-100's and different cables and the screen would flicker between the picture and signal lost. I found a link in the FAQ on dtv's site that said this happens when you use the HDMI connection sometimes. Has anyone has this happen and if so, how was it resolved? Did dtv replace it? I just want to know before I call and berate a human as to what I can expect. Thanks in advance.
