I am debating whether to get my set swapped or at least re-calibrated. The picture is always milky, regardless of settings. The four corners are always much paler that the rest and down the middle and the right hand of the screen is a lot of noise. It looks like the middle and right hand side are darker, especially when displaying solid black or blue. I have an IXOS XHT601 cable connected thet set to my Sky+ in RGB mode. Wven terrestrial is not very good. Any thoughts?
