Ihave Panasonic 37" Plasma Screen with Separate Tuner.The connection isRGB from board attached under screen to RGB Tuner Then Scart From AV1 (RGB)Tuner to Sky Plus. My problem is shadowy vertical approx 1" wide broad lines on Sky picture and recordings. They are mostly visible on green backgrounds and light grey backgrounds particularly on Sky Sports Football. I have had a second brand new Sky+ box Amstrad fitted and the problem will still not go away, so it is not the Amstrad Box unless it is a compatability problem with Panasonic Plasma Tuners/Screens. Has anyone else ever had this problem and if so what is the solution to fix it. I have tried every obvious method to no avail.
