I have a JVC AV-28x4 TV, it's only 3 months old. I am experiencing a strange and irritating symptom. Down each side of the screen, there is a slight pattern, a bit like faint vertical pin stripes down the screen. The best way I can describe it is it's as if the density of the pixels or the resolution of the picture graduates away as it nears the edges of the screen. It is present on any source I select and regardless of the TV's Zoom setting. I thought it may have been the Panoramic setting, which as I understand it, maintains proper aspect ratio in the centre of the screen, and stretches it the further towards the edges you get. But whichever picture format setting I use, the problem is still there. Any suggestions?
