I bought a JVC 27s33 yesterday and I'm liking it quite a bit, but there is a small color "weirdness". If I turn my tv so its screen faces north, a green spot appears in the upper left and a red spot appears in the bottom right corners. If I tilt it any other direction the corners of the screen are slightly darkened. I think that both problems are less than they were yesterday but it may just be my imagination. Should I take this back? or is there a chance that it is actually clearing up on its own? I have 30 days before I need to return or exchange it so should I just wait a bit to see if it clears up?
