I have recently bought a fortec receiver and connected via scart (I have also used the video lead and also aerial lead too) but on my tv am getting lines as shown on the images. I have tried all different modes of connection to tv and all settings on digi box but lines are still there making viewinghard. I have no probs with my sky box or dtt receiver only this fortec box. I thought that may be interferance lines so switched off everything but lines are still there.
