I have a Mitsubishi widescreen TV. When I am watching anamorphic discs the TV plays them back fine. But lately I have discovered a strange phenomenon when I have the TV set to regular standard mode (non anamorphic/widescreen). At certain times in standard mode one gray bar on one side of the screen will be significantly larger than the other one. Instead of 50/50 in terms of their equality on the sides of the TV picture they can get up to 70/30. When I called my service tech to ask them about the problem they were stumped. I noticed that the change happens slowly. This morning they were pretty equal but now its more along the lines of 70/30. Anyone have any ideas why or how this can happen? Thank you in advance!
