Further update:
Things have happened remarkably quickly with this and I have to say that the speed of this service has been amazing so top marks to Samsung!
So the authorised service centre have called and after describing the issue it's a known fault with this range but the bad news is it requires a new panel to solve it
The good news is that Samsung authorise the repair company to carry out the install of the new panel at my property so the repair agent has ordered the panel which will arrive on Thursday so the repair will be done on Friday and take about half an hour. They will confirm on Thursday evening that the panel has arrived and call on Friday too with a one hour time slot for the repair so I'm not waiting in all day. How refreshing is this guys, this is what I call good customer service so all other manufacturers should take note as this has been faultless so far.
The bad news is that my THX professional calibration will now be wiped and I presume need doing again, this is a problem as I really can't afford another £225 for it to be recalibrated. I will contact Jules and see what he says, hopefully we can come to some arrangement but I'm not very hopeful in all honesty. Gutted that the calibration will be useless but considering the response from Samsung to my issue I can't really grumble too much I suppose but it all means extra expense that I can't afford right now.
