DVD to Projector via component cable. DVD set to Progressive / Widescreen. Projector set to Progressive / WScreen.
All this worked fine for several weeks until I played a DVD-A.
Since then, the image on normal DVD has been split 3/4 of the way down by a black line, below the line the first 1/4 of the image is repeated. I assumed that this was a Progressive scan problem, not so, because when the image size is altered to 'Full through' the image is fine and when the Pr'gsve is is set wrong the projector just displays the blue screen.
Will a 'hard reset' cause any harm / can anyone suggest a fix?
