I bought an open box samsung LNT3242H yesterday and have been happy with the quality of it so far. However, on the right side of the screen there times where it looks like the lighting is very dark compared to the left side which looks normal. Other times the spot will appear very faint, while other times it is very distracting. What could be causing this and is there anything I can do to fix it? I bought EW through Circuit City and they said that they could replace it if it can't be fixed through Samsung. Anyone have any info on this?
