Hi, I have a JVC XV-N55 DVD player. Its works well up to a point when a scene in a movie is dark. The TV goes blank and "input" shows up on the screen. I'm thinking that it could be a setting on my DVD player but all the things I have tried have not worked. I have Sony Trinitron TV ( Pre-Wega) which is connected to the DVD Via SVIDEO. Any Ideas? Thanks
