Hello and sorry you're having problems. Issues which show up as a distinct difference between the left and right side of the picture (generally a double image, etc.) are generally caused by a faulty LCD timing controller (T-Con) board. This is on average a $200 repair on this set and you can use either of the following links to locate a shop in your area. Please keep in mind it does not need to be a certified "Samsung Service Center" as this fault is common among all brand and model and any certified repair shop can tackle this.
If you need further assistance let me know. Please do not forget to click at least a 3 STAR RATING, at the top of the page for my efforts. You can follow up at any time if needed.
