So for the past 3 months I've had 3 separate Samsung Q7Fs. The first suffered with a blue mark at the bottom of the screen and the next two (both v2 screens) had SEVERE shadow problems and Samsung have F***ed me around something chronic with it. As I said already, 3 months. They are claiming that this is within spec of the TV. Make you're own mind up. from the attached image. ANYWAY! I finally have them sending an #engineer out to look at the fault, something which literally took them a week to sort out in the first instance, and basically, unless they can offer me something seriously magical (which I doubt), I'm just going to get the code I need and claim a refund from the retailer. The only comparable screen I can see is the LG B7V. What are peoples opinions?
