I have recently brought a JVC AV-28x4 Widescreen TV which I have the following problem. When viewing a 4.3 format broadcast I get the normal black banding left and right of the screen but the vertical lines curve into the middle! There is about a 1-1.5cm difference in the thickness of the lines at the top and middle.Picture attached) I have contacted the company I brought the TV from and the told me its because the TV is a 16.9 widescreen and not designed for 4.3 format. Yet the settings has a 4.3 auto display feature! It would also seem that when viewing programs any vertical lines in the broadcast i.e door frames also curve so it would seem to be a tube problem. You comments are welcome.
