Dark Vertical Banding on UN55MU7000 - Software version: T-KTMAKUC-1270.3

I have a Samsung 55" 7000 series TV that is less than 2 years old and has what I once thought was one dark vertical band, but now it appears there are two dark vertical bands visible at all times in my television picture. Additionally, the bands appear to be getting worse, which would explain why I am now seeing two vertical bands when I previously only noticed one.  

 

Here are several pictures of the issue taken today :

I posted a reply on another thread with a similar issue, but with a different model and the SamsungMod @SamsungMod23 suggested I run the Picture Test under Settings>Support>Self Diagnosis>Start Picture Test.   The test failed all 3 tests (see attached Picture Test Result screen below)

This issue seems to be extremely common, based solely on the number of posts in the samsung.communtity.com forum by users experiencing similar, if not identical, issues with their Samsung TVs.  It also appears this issue is prevalent throughout the entire model line; 6000 through QLED and is also prevalent on Samsung TVs going back several years.

 

This is extremely frustrating and disappointing as I had always thought of Samsung TVs to be very high quality, and the sheer number of users reporting experiencing this issue makes me question the quality of Samsung TVs.

I have the same problem and very disappointed in Samsung. I filled out the check for warranty form and they emailed me back with a headline of, Warranty Approved, then I read the rest of the email and it said Out of Warranty 01/17/2019. I paid a lot of money for Samsung UA75MU8000FXZA to only last less than 2 years. I can't see me buying another Samsung product.

Thanks for the warning !! typical samsung from what i have been hearing .. never will be buying another product from them thats for sure.. look back at there folding phone screen that had problems..  Sure didnt do any testing before releasing it.. and also the phone that would catch on fire.. some airline wouldnt  allow you to even have it on flights.. I know i should of bought a Sony tv instead, my other tv is a Sony and has had not one problem and a beautful picture for 15 years now

Your wasting your time, likely the backlight strips are bad and the diffuser is melted.  I had the exact issue.  No amount of troubleshooting is going to correct it - it has to be repaired or in my case cheaper to just purchase another tv.  I had to after barely 3yrs.  I have a house full of samsung products, watches,tablets, phones etc.  Im all about samsung but sadly im being rewareded with disappointment.  Good luck to you my friend.

I have the same problem with my 75" QLED (QN75Q7FN) purchased in November 2018.  This is a horrible situation when you spend over $3k.  I currently have four other Samsung TV's in my home but may rethink my dedication to the brand. Very disappointing.

I just wanted to give an update on the situation with my TV.  A moderator replied to my post on here and asked me to PM them with the details of my television, which I did.  Samsung support emailed me, asked me for more information and pictures showing the issue.  I sent them what they asked for and then they scheduled a technician to come to my place and replace the display unit in my TV.  They came out and replaced the display unit (took 2 visits b/c the display unit didn't come in before the first visit) and my picture is back to looking perfect again.  Hope this is a permanent fix and these new display units don't have the same issue.

 

Thank you to Samsung for making this issue right, even though it was outside the warranty period.

I had the same problem and solution from Samsung. My tv is back to normal after warranty expired. My UA75MU8000FXZA panel was replaced with a MU7000FXZA panel which no one told  me that's what they were going to do. Are they different, I know the cost when buying the tv was a lot different. The power supply was going to be replaced  along with the panel. When the tech took the power supply out of a open box, you could see the circuit board was broken, so no new power supply for my tv. This whole process took about 2 months and I still have the old panel sitting in my living room. They don't seem to want it very bad. I've called many times and I've had my ticket number canceled 3 times making it difficult to contact them. I received and email stating that the trucking company will contact me but nothing yet. I am glad to have my tv back though.IMG_2725.JPG
