i bought a samsung lcd tv, 650 series, at xmas, brilliant picture, until recently, i,ve discovered on the right hand side of the tv, there are a few vague black lines showing, when i,m watching it. i have my tv hooked up to a sky hd box, could this be causing a problem? i don,t know, but the tv has built in freeview, and when i change to watching the tv through that, no change, thin black lines are still there only on right hand side of screen, anyone with any ideas
