Samsung TV UE65KU6400 vertical dark band

[rikkog]

Hi there,

My just more than two year old (and therefore just out of warranty) television has begun to show a top-to-bottom darker area or shadow just to the left of centre.

I was appalled to learn that a local Samsung-recommended repairer has quoted me €200 MORE THAN THE COST of the original television(!) just to supply the part - labour NOT included!

I am obviously very disappointed that such a new and expensive television is showing such a problem - I understand it is a problem that other people have experienced... Is there anyone from Samsung who would care to comment on this matter?

Many thanks

Rik

I would love to know more about how I’d go about doing what you were able to do if you get a chance to respond. Just happened to mine a few weeks ago and I was sort of resigned to the fact that I made a bad decision to buy a Samsung.

Just managed to solve this issue by changing the display mode. No idea why it worked, but it did. Randomly trying anything to see what might help, in the General Settings/ System Manger settings menu I changed the usage mode to Retail Mode. The dark strip all but disappeared which was great as it showed that it wasn't a hardware fault. However the advertising strip that keeps appearing is more annoying than the dark strip. Changed back to Home Mode and cycled through the display modes. Initially the dark stripe occurred on one or two of the modes but as I cycled through them, it disappeared. Since then I have noticed a very small area, bottom of the screen, slightly left of center that appears slightly "off". However this is barely noticeable, especially compared to the thick dark vertical band that was there before.
TV is UE55NU7100 model with software version T-KTM2LDEUC-1330.5
The dark stripe, same as OPs picture appeared 7-10 days ago

Edit 12/11/2022 The dark vertical band has not reappeared.

Just back up on the problem. We are in UK and my 75" is 15 months old and the dark stripe is pretty bad. Samsung helpline take you to Picture testing eventually and then say TV needs a repair, but the problem is not known to them !!I have a company to contact re-repair but it's really pointless as the cost will be too high based on other blogs.They must know and should take responsibility for this fault, as it's a £900 TV and 15 months old. new set will not be Samsung for sure.

I have the same problem with my 65 inch Samsung, the dark band started on the right side about 4 inches wide, it has now moved to the middle of the screen and it is a good 18-24 inches wide now. My TV was just about 3 years old when the problem started. With what you pay for these QLED TV's you shouldn't have to deal with these problems and Samsung should man-up and stand behind their products.

It sounds like a panel problem but my concern is you replace the panel and the problem comes back (this has to be a defect in the design of the panel), unless Samsung has fixed the defect so they know it won't happen anymore.

My TV is a 2018 model, I am curious to see if anyone here has a 2021 model or newer with this problem.
