Well I'm going thru my 3rd 46XBR3, and have already sent back another 40XBR3. Besides the clouds and distorted picture, has anyone had a problem with night scenes having a green tint where there should be black? Even the actors faces and hair, in low light scenes have a green tint to their faces and hair. I've spent hours trying to tweak the picture ,only to make others worst. Seems like the longer the Tvs' on the more green shows up in the picture. This set is by far the worst of the ones I've sent back. Anybody have any suggestions. Thanks.
