so the top and bottom 1/3's of the tv shows green dots that covers about 20% of those 2/3's. The middle 1/3 is fine. This now happens when cold and clears up when the tv warms up after about 5-10 minuts. The tv is around 2 1/2 - 3 years old. Can this be fixed or is the tv on the way out and its time for a new one ?
