little bo,
I'm not sure what it could be. But it does sound like it requires the latest firmware update. Have you tried installing that already?

Good Evening,
So we just recently purchased a new 52 inch,i tend just to use it for games and have had no issues (except a few on intros on the ps3) and my wife uses it for movies and tv.
I am becoming very frustrated as i often see red contour lines on shading this occurs through hdmi, pc-tv and strangely never on rgb scart for games but through non hd sky happens often.
I have gone through every setting and it makes little difference, to compound the matter it does not always happen, now is it an issue with the set?, the cable quality im using? or am i just being very stupid and missing something?
Any help or advice would be appreciated
Regards
