"The colors hurt my eyes" is more a description of you than of the set.
Please be more specific about the set itself.
When you turn the contrast down "the black level suffers." Do you mean the blacks are too dark, or too bright?
Certain colors bother you. Does the picture look too bright or too dark or have an over-all tint when you turn the color all the way down and view in black and white? Can you get a pleasing result for the problem colors by turning down the color control? Are other colors then too muted?
