ummm, i know if contrast is set too high it can turn the bright whites and greys into a pinkish color.
go download the avs709 calibration disc/usb and start from there.http://www.avsforum.com/t/948496/avs-hd-709-blu-ray-mp4-calibration
scroll down to the mp4 part and download the mp4(.7z), extract the mp4 and burn it to a dvd. most newer bluray players, ps3/360 will play the file.
watch the video that is on it as the two guys explain what you should be doing to basic calibration.
also hdtv color is generally set to 15-235 while computer monitors are set to 0-255. 15 or 0 is the blackest black, 235 or 255 is whitest white. to a computer 15 is not fully white and 235 is not fully black so you will see washed out whites and blacks if the color grading scale output to the monitor/hdtv isn't correct.
