Hi i have a grundig 17" lcd model lcx17wsi. The problem i am having is when using my gamecube console and trying to play a game ion 60 hrz mode the screen goes black and white and jumps. Where the mystery lies is that when i put a region 1 dvd into my dvd player the tv plays the film fine and the tv menu even changes to ntsc instead of pal. It wont do this for my gamecube though. Any help on what i can do?
