Had this TV for 3 days. Initially pleased with it but starting to realise that this unit displays most of Sky channels very poorly compared to 2-year old Sony CRT. Is this the TV's fault, Sky's or both? The best way I can describe the picture from LCD is blocky (on faces it's especially noticeable), as if watching poorly quality MPEG. Some SKy movie channels are better but still nowhere near quality of older Sony CRT. Even watching DVD via high quality RGB scart is worse than CRT. Sky+ is recent Pace, signal strength c. 80%, Signal Quality c. 90%. Any else had same problem with this or other LCDs? Any suggestions to improve things? Bought it off the internet and presumably I have 7 day cancellation rights, but I need to decide whether to return it soon.
