rdavisunr,
Well, it's great to see that you did the test on all the inputs - so it looks like it may be an internal issue at this point. I might suggest calling 800-SAMSUNG to schedule a repair tech. You should probably still be under warranty for that, but if this issue slowly appeared, it's best to get it professionally looked at.
Keep me posted.

Samsung technical personal, thank you in advance for you response.
When I arrived home tonight and turned on my LN46A550 I discovered that all the white color reproduced on the screen seem to have a pink hue to them. The problem becomes more obvious when the on screen white color is bright. I believe this problem is isolated to the set as I see the same issue from multiple types of input sources (Cable TV Box with DVI-HDMI connection and an AppleTV with a straight HDMI connection). Any advice you can provide would be appreciated. My current firmware is 1006.1.
