Hi, I've just taken delivery of a TX28PS5, overall it's a good set but I'm having a few probs with the picture. Mainly, as the aerial is crap, it's hardly used and so I do most viewing through Sky. Problem is that when using "Panasonic Auto" for aspect switching, it's very unstable. That is that it keeps zooming and cropping the picture at different intervals (only through AV). I can stick it in 16:9 mode of course, but it a pain to change it manually. Anyone had any experience with this? I've also noticed the Sky onscreen banner is quite distorted on the TV and while normal picture seems fine, if you view digital service like BBCi the picture seems to taper quite noticeably in toward the right of the screen. Again, any ideas?
