Purchased the TU7020 6 months ago and have issues where there are lights in 3 corner and along the bottom which are bleeding through and it’s impossible to enjoy watching this tv. rang customer support who spent 2 months going back and forth and then eventually I spoke to lady called Laura in customer services who told me it’s within specification…i none of my documentation that came with the telly does it say that I could experience this issue and then refused to help me any further, I asked to be put through to her boss or someone more senior, she point blank refused. SHOCKING CUSTOMER SERVICE AND SHOCKING PRODUCTS. Falsely advertising crystal clear picture. Will never buy anything Samsung again and I urge everyone not to either. You won’t be looked after if you encounter an issue. Waste of a £1000.
