Joe, can you please get me the model number written on label pasted on back cover of TV?850fh-yb03 is display panel part number of Samsung TV.

Thanks for TV model number info and please reply here to continue troubleshooting, do not open fresh question for same TV.
Do the screen has horizontal bars or thin lines?
OK, is it possible to take a good picture of rear of TV showing all circuit boards, specifically located on left side and post that picture here, please use add-file link located below the box where you type the reply to attach the picture.
I want to check that I'm looking at correct manual for the TV chassis.
I'm online now and think its not too late.
