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.
I bought a 75" Samsung JU7100 in September of 2016 because i was a proud owner of a Samsung plasma TV that had lasted for over 7 years (still works great till this day). Unfortunately I can not say the same for my 75". Last year around December i started noticing vertical banding. My warranty was up but luckily i bought a 3rd party extended warranty. After calling several times and sending pictures they replaced my TV with an LG. I'm quite disappointed that the TV has only lasted me for a little over 2 years since i paid about 3 grand for the TV at the time. This was the last of their 3D TV's and even though some have moved on I still enjoy throwing in a 3D movie to watch. Needless to say after reading this thread i will no longer be purchasing Samsung TV's until they get this figured out.
Same over here! We called Samsung and they gave us the info for an authorized store that can fix it but they want to charge us $1,500 because according to them its the screen. That price is ABSURD and for that we just buy a new tv! Come on Samsung.. theres gotta be something you can do. There are a whole 25 pages of US, CUSTOMERS, having the same issue!!
The links below are to the pictures. I wasnt sure how to attach them
Hello, My original request went into Samsung on the 21st of July. I have had an authorized service tech come to my house and verify the problem with the vertical lines. That was three weeks ago. I continuously am being told that the exchange department will call me back in less than 2 days. (2 days not 2 weeks). What is the story? This is a known defect with the TV, is the goal to see if I stop calling? My patience is beginning to wear thin. Is there a direct line to US supervisor to talk to?
