My Sony 7700 is about 6 years old. Of late the picture has a green tint to it, usually shows on peoples faces. The green will come and go. At first i thought it might be my TV, a Sony 36" XBR, only 3 years old. I checked the picture on satellite when the DVD picture was green, it looked great. Then,switch back to DVD, and its green again. I have my player hooked up to the component inputs. Any thoughts?
