Yes,your model number is wrong,if it's an LG & it's a 47LN something,then you can replace the strips,from e-bay or there's a company called Ohm supplies,they sell the strips,or if your soldering skills are good,the individual led's!There's also a guy selling genuine LG replacement led's & fitting instructions on e-Bay 10 x led's £10,so although time consuming could be worth while.
