I recently got a new Samsung Plasma 50" and heard I should run a plasma burn-in dvd off the net first. So I turned it on and tried messing around with settings and such and hooked it up to my laptop through PC inputs hoping to run the burn-in file off of it. However, when I started it up showing screens of different shades of color, I saw the TV menu burned in already in the background!!! I turned it off and am afraid to turn it back on now! Can this happen with in the first 30min!??
