I also have a Sanyo HT28745 that is exhibiting the green tint problem. It started within a week of it turning two years old. I called Sanyo, spoke with Harvey and he stated that the green tint problem didn't happen to these models only the earlier models. The green tint problem being described sounds exactly like what is happening to mine though. Harvey basically stated that I am on my own. Sanyo hasn't received any complaints on this model.
Has anyone else with a HT28745 experienced the green tint problem? If so, how was it fixed and did Sanyo do anything about it? I realize the TV is out of warrenty, but I am really ticked off that a 2-year-old TV is now in need of repair.
