I have my TV hooked up to the TV (720p) via HDMI. There seems to be some major graphics glitches/corruption when I use the device. Whether I'm watching a video (at first I thought it was badly encoded file) or navigating the menus, there's glitches all around. Some are weird distortions, other times it's streaks of red pixels. The artifacts look like video card errors, like when I over-clock my desktop's graphics card and the heat makes it screw up. But that's just a hunch. All other devices (1 hdmi, 1 component, 2 composite) show no problems so it's not a TV issue. I'm hoping someone has had this and knows a quick fix so I don't have to send the *TV in for service. Any clues?
