I recently purchased a 42" plasma samsung PN42B400P3D, and when I plug in the standard red, white, and yellow cables to the back of the tv, the playstation image will show up, however, it is grainy, black and white, and there are blue lines across the tv screen. This happens no matter which configuration I am trying to cords in. I am able to get sound, but the picture is horrible!! Any ideas why this would be happening? Do I need different cables?? Not sure what to do about it! Any help would be much appreciated.
