I have a noticed the following on all sources (DVD, DirectTv, VCR). When viewing a very white scene, hockey is the most obvious, I notice a very faint verticle line down the middle of the set. Thats not so bad. The bad part is that the left side of the verticle line has a noticeably darker tint. Not dark, but definitely a darker tint. So when watching hockey, the ice on the right side looks bright white. However, on the left side it has a tint. This splits the screen exactly in half. On most darker material its not seen. Any ideas what this might be? I have only owned the set for about 2 months and feel this may require a call to Toshiba.
