Hi . I just got a Samsung theater in a box unit ht-tq72 and I connectted it toa 4 year old Sony 32 in flat screen . I used the component cables , red blue and green , and when I go to play a dvd I get lines from the top corner of the screen to the bottom corner . . There is good sound but you can't see the picture. I tried out he audio component cable and I did get a good picture . The Samsung says on it that it is a progressive scan . Whats going on .
