My Sky+ box is showing horizontal lines which are noticable when there is a large area of any one colour on screen. Is this connected to the "Vertical Banding" problem that is well known? Just to make it clear the lines are running horizontally across the screen. After a quick search on the forum there ain't many mentions of this problem.......... is this an isolated case? I've checked connections etc but they are ok. The banding is even visible from my TV upstairs which is fed from the RF2 output.
