Bought a new OLED TV from Currys 15 months ago. Model OLED65B7V at a cost of over £2000. I now have 2 wide green lines across the bottom of the screen known as burn in. It appears this is from watching the news channels that have breaking news banners. Using "You Tube" to display a red background I can see the logo BREAKING NEWS on the bottom left corner of the screen. The guarantee does not cover burn in and any attempt to remove the burn in has failed using the TV pixel refresh options. What a waste of money. Will have to bear with it until I can afford a good Samsung QLED TV.
