Right... update time.
Feel a bit of a fool right now, had the man out from John Lewis's repair partners. Now before he came out i did what the lovely lady at JL tech help said and did the factory reset option. Now i did this and could still see the vertical bands on the right of the screen. The next morning was the day the repair guy was due and intentionally put the tv onto the Everton vs Wigan game as football matches made the bands stand out. But guess what i could hardly see the bands!!! This was on the Normal pic setting so i then switched over to the Pro settings listed in this forum and ta-da, couldn't see them at all!
To late to cancel the repair guy, when he turned up i apologized for wasting his time, and explained the situation. He had a quick look at the picture and said he also couldn't see anything.
So instead of him taking it away for no reason, i decided to keep it, but as JL have the problem in the system if it comes back ill be in a good place to get back to them.
If its stays away ill be so happy as apart from the now non-exsistant problem the tv is amazing.
