I have recently purchased a 444 from Richer Sounds and I am suffering problems with the picture quality. During bright scenes in films the top part of the picture is much brighter than the problem. This is very noticeable in the black band of the widescreen. This only happens in RGB mode and I know that it is not the television as when I plug in my Panasonic A360 using the same scart lead etc then the picture is fine. Can anyone give me any ideas what may be causing this as I want to make sure that I know what I am talking about when I return the unit to Richer Sounds. Many Thanks for any help.
