KS8000 65" Overheating and Backlight Banding

JUMP TO SOLUTION

Hi, as mentioned in the subject, my 65" KS8000 bought in 2016 is starting to experience massive backlight defects around the edges.  Some edges have extremely bright blue LEDs, some places have backlight banding from the bottom to the top, and some areas just have strange bright artifacts on the panel.  Also the TV is so hot in these places it actually burns me if i touch it, I'm legitimately worried about my house catching on fire.

 

From what I have gathered from other posts, it seems as if these units eventually start to go bad, overheat massively (for one reason or another), and panel separation starts to occur, my guess is the LCD panel from the backlight diffuser.

 

I've been a longtime customer of samsung products, TVs, multiple phones, computer monitors, but this seems awfully bad to me for a high end TV to die in 3 years of ownership.  I don't really want to pay 100$ for a technician to come out to tell me what i already know, that the entire panel needs to be replaced for what is essentially the cost of a brand new TV.  Is there anything Samsung support can actually do here?  Happy to provide details in a PM.

This worked for me:
-Unplug tv from a power outlet, let it sit over night
-Turn on the tv the next day, turn off hdmi uhd color, lower your tv's resolution to 1080p

 

During the first two days with this setting my tv flickered two or three times for a couple of seconds and then it would go back to normal without me doing anything. After two days the picture has been rock steady for three days now. I’ve also noticed that my screen is radiating less heat now.

 

I suspect this to be a software bug or the update just didn't sit well with the tv.
I hope this will get resolved with the next update, I am curently on 1242.

My issue (and many others') is not a software issue, it's some issue with the panel (or t-con board which is integrated in the panel). Unplugging the TV or leaving it off for some time to let the TV cool down will only temporarily mitigate the issue, but then the issue will gradually reappear again in my case. At first the issue was not so bad for me but it has progressively gotten worse.

 

As it seems to be some known issue Samsung kindly agreed to repair mine out of warranty. Already had the tech come to diagnose the problem and they confirmed it was a panel issue, just waiting for the new panel to arrive now.

Yes, you are right. The flicker came back.

That's it, I'll never buy another Samsung Tv again.

 

End of story.

I'm having the SAME EXACT problem with mine, how did you get Samsung to help you? I spent a nice penny on this TV and would like Samsung to help if they want to keep a customer.

I have the same exact issue.  I started occuring about 1 year ago but at that time switching off the ECO mode worked but now it has come back.  After just 30-60 minutes of being on it starts flickering and can't be watched.
