Hi Steve

I'm sorry to have to break this news to you its a bad LCD display, thats about the worst thing that could happen with the set, unfortunately its not an option to replace the display panel (screen)because of the cost it would exceed the cost to replace the set as new.

Steve your best move is to complain to samsung, manufacturers are very aware of panel failure its a very common occurence and are known to help owners who have had their set for less than 3 years.

I am sorry I dont have better news than this I see panel failure it on a daily basis.

Please let me know if you need more info

I know its not what you want to hear however it is the right answer and I would be grateful if you could rate the answer as OK or better as this is the only way I receive credit from the site.

Many Thanks
