Sony Wega KP-46WT520 Color Problem on HD Inputs

Bought my inlaws a bluray player for Christmas and when hooked into the component or hdmi inputs the yellows appear neon and greenish in color and no true reds are present.  When hooked up the the rca input it is fine.  Coax input is fine too.  They have never used the component or hdmi inputs so this problem was just discovered.  Brought my bluray player over and it does the same, changed hdmi cables and component cables and have concluded it must be the inputs on the hdmi and component inputs on video 5, 6, & 7.  What would cause this and how can I fix it?  Thank you!
