i have a phillips lx 3750 w surround sound dvd player. it was playing fine dvds of all regions. however it seems to have developed a problem in that any dvd will play but only with two screens of the same thing side by side and poor quality.

i have tried to unplug and change across the scarts but no luck. any dvd thst i put it starts sound fine but with the screen in duplicate side by side. help please
