So did this issue eventually get fixed? Per customer support I need a technician to come out and diagnose the issue. It's been just over a year since we purchased the TV. I'm just wondering if the technicians have even been able to do anything?
I've had my panel replaced Feb 2018 for my 75inch Samsung mu9000 and called again a few weeks ago about a stuck pixel and they have offered to refund me. So it must be true Samsung can't afford to repair these faulty panels.
I’m having the same issue with NU8000 75 inch. This will be the second time on the same tv and I’m really upset. To spend almost $3000 and to get this is a real disappointment. Bought this tv 1 year ago and going on second panel. It comes up after a few weeks of use. I do not want this product line and I’m hoping they’ll replace the tv with a different model.
Just to add to the conversation, I have an older model 75" 4K, a UN75JU7100 bought in October 2015. We paid over $4200 for this TV at Best Buy and at first I didn't notice the banding. In fact I first noticed it during horizontal panning of a football field but I wasn't sure what I was seeing. I think the problem actually worsened over time and now it's visible pretty much anytime there's a darkened scene. When I did contact Samsung about it I was out of warranty and of coarse they tried to say it's normal and had no interest standing behind it. My 46" Vizio ($650) and 60" Insignia ($250) both look much better and it makes be sick. On a side note, our high priced Samsung fridge display also failed. Other than phones I'll never buy another Samsung product. Our latest purchase was an expensive Kitchenaid dishwasher. I never considered a Samsung even once. Hope others steer clear based on this and other's testimonies.
This is normal I have a Bolva brand new and it's doing this same thing I sent the first one back thinking something was wrong. I'm hoping they have some kind of firmware update for this.
I started with a Samsung Q7 QLED. When I quickly found the horrible vertical banding, among many other troubleshooting steps, I tried using the link above.
The banding did not appear in the picture test. The link says that, if the problem doesn't show up in the picture test, the TV is fine and the problem is with either the HDMI cables or the source. In my case, I've used the same HDMI cables and the same sources with 3 other TVs, and there was no vertical banding. With the Samsung Q7, when I tried various sources and different HDMI cables, the banding was still present.
I subsequently returned the Q7 and replaced it with a Q8. The vertical bnding on the Q8 was even worse.
I returned the Q8 and replaced it with a Sony OLED TV. With the Sony, there is not even a hint of vertical banding (with using the same sources and the same HDMI cables that I used with the 2 Samsung QLED TVs).
Thus, I found the information in the link about the problem being with the HDMI cables or the source to be inaccurate, and the link is hardly a solution to the problem.
