Thanks for posting the transaction number. I passed along your request to the appropriate party; you should hear back very promptly.
Model UN55D8000YFXZA 18 months old and out of warranty by 6 months. A 6 or 8 inch gray bar started appearing on the bottom of my screen. It is a gradient bar about 6 inches high going left to right on the bottom of the screen. Sometimes the upper left half of the screen starts refreshing slowly and looks horrible. I called Samsung and requested a one time warranty but have not heard back in over a week from them. My ticket number is 1109674434 if any Samsung techs are reading. Any help is appreciated as maybe there is a simple fix.
