I purchased the 60" Sony SXRD XBR a few months ago and noticed on this model that the letter box lines are not completely straight. They curve up a bit on the edges. It's very slight, but still, shouldn't they be straight as an arrow?? especially for this price? Anybody else have this problem also? Checked the same exact models at other stores and they all have this problem. Even had a Sony tech come out to check and he says b/c of the LCOS technology, this can't be straightened. Let me know if you have this problem and if you were able to fix this. Thanks!
