I have been getting a verticle black line along the outside edge of the screen whenever I am using the HDMI input from the samsung dvd combo recorder? It occurs while watching dvd's or vhs or tv signal through the unit. The verticle line dissapears whenever I watch the tv signal directly from the satellite box via S video. So it seems the problem is with the samsung unit. Any ideas what could be causing the black line on edge of screen? It is about 3/4 of an inch wide. Its like the picture is not going to the end of the tv screen.
