My television has started to have screen problems, in the areas that should be dark the screen is green, I left the television on for a while to see if this effect would fade but it has remained there.
On looking at the operating manual under trouble shooting its says:Strange colour, light colour, or dark, or colour misalignment------I have tried to do as it says, Adjust picture tone, checked the colour system setting and checked the HDMI Setup setting, but nothing changes this problem, can anyone tell me why it is doing this?

Uh Oh! Your light engine is warping a little from overheating and
is distorting the picture. It usually means replacing the light
My suggestion to you is to get on the phone with Samsung and start
complaining, then keep complaining until they agree to pay for it. You
may have to get the problem diagnosed by a pro before they agree to pay
for it though.
Hope ya fix it!
The back light is beginning to fail, thats why it goes shaded but you can still the picture on one side, do a google search for back lights for your make and model, there a few how to's to help you with changing the back light.
This is no solution but a point in a probable direction.
A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.
it sounds as if there are speakers to close to the tv or the built in speakers are not magnetically sheilded properly (maufacturer defect) if u have or have ever had speakers on the left and right side of your tv then the magnets in them will discolor and distort the screen. sometimes even long after the speakers have been moved away from the tv it will still look that way. you may try going to the library( or online )and looking in tv repair books on how to build a homade degauser unless your tv has that feature built into it in the menu somewhere like some computer monitors do. I had placed the front speaker of a 5.1 surround sound system on top my tv and it cuased that same problem, but i found out that by placing a small round magnet with a hole in the center on top of the tv (after removing the speaker for good) right where the discoloration was.. had to flip it one side or the other to get proper effect...it immediatly took away most of the discoloration and over time it disappeared. I hope this helps. Please email me at email@example.com as to your conclusion in case it will help others. thanks, Adam
