I have been banging my head against the wall trying to figure out what my problem could be. I have a UN55B6000VFXZA that have horizontal black lines along the top of the picture, ghosting along the top 3/4 of the picture, and a completely normal bottom 1/4. So far I've:
-Performed a factory reset from the service menu
-Installed a replacement t-con board
-Opened the panel up to press on the tabs to make sure they're not loose and everything is pristine and no matter how hard I press I get no results.
The ONLY thing I don't know is what type/model my tv should be listed in under those headings in the service mode. I'm guessing that an incorrect setting MIGHT be causing this problem. Anyone have any suggestions, I'd love to hear it.
