The TV is changing the INPUT 1 HDMI signal to DVI on its own. It also loses the sound! I have an HDMI cable on INPUT 1 and a gold set of the 5 component on INPUT 3. I have to switch to INPUT 3 in order to watch TV with a 480 picture but at least I have sound.
I unplug the TV for 2-5 minutes and then when I turn it back on, it will stay on as HDMI INPUT 1 for 2 to 15 minutes then it changes to a pink screen and no sound. After a minute or so the picture comes back but no sound. The TV is doing this on its own. I updated the software and still no change.
