The product (LED backlights) did exatcly what it was meant to do. The TV picture is now returned to when the TV was new and tyhe blue tinge had completely gone. It was relatively easy to fit due to a video on U Tube showing step by step instructions. The only repeat task was reconnecting the 2 ribon cables from the screen to the control board. We didnt do it correct first time but it worked when disconnected and reconnected.
The help desk was superb in that they gave us the part number needed for that TV but that was only confirmed when we took the whole thing apart. It needed 3 LED strips that ran vertically and not horizontally like the U Tube video. All in all a very successful excercise that meant for £52 we had a working telly instead of £800 for a new one!
