What kind of picture options do you have? I'm not familiar with this particular panel but do you see such things as, "Natural", "Standard", "Movie", "Cool" or "Game" settings/modes somewhere in your menu? If you're stuck in the wrong one of those, then even making changes to brightness, contrast, color, etc., will only go so far in changing the image you see. You might be set in some cool/bluer image mode when you were in a warmer mode, such as movie mode, before with your old set.
Mourning the disappearing usage of the -ly suffix. Words being cut-off before they've had a chance to fully form, left incomplete, with their shoelaces untied and their zippers undone. If I quote your post (or post in your thread) without comment, please check your zipper.
