- UN65KU7500 Samsung Curved TV White Spots problem overheating problem, melting problem. Burned/melted Light Diffuser.
This is a BIG PROBLEM.
1. To fix this unit, LCD SCREEN needs to be replaced (NOT ECONOMICAL if TV is out of warranty).
2. Can this unit cause more damage (fire, burn etc).
3. Does Samsung need to address this issue ASAP?
4. Does Samsung need to recall this model (and maybe more edge lit models)?
This is a first unit we saw with this damage. We checked some sites and saw many pictures with the same symptoms. I decided to make this video in hope that owners of the same TV model will be aware of this issue. It may effect other Samsung KU models with edge lit backlight.
Please comment below. Thank you

UE48JS9000 - same problem. It seems to start when there are minor cracks caused by the heat - these cracks then heat up more because they become a reflective surface that channels more light ..... over time the cracks get longer and the edges char.
First warning sign is small fine slightly brighter lines at the edge where the LED are...... very small to start with but will grow over time and spread along the edge...... the charring will then occur.
Once it starts there is no stopping it and eventually the edge/s where the first cracks appear will gradually worsen..... and the worse it gets the more heat gets channeled by the imperfections the quicker it gets even worse .... vicious circle of feedback effect.
Luckily I had a 6 year warranty ( thanks Richer Sounds U.K. ) and I got a full credit for the 2021 equivalent.
Don’t even have to return the old one so I had a look to see what the cause was.
The actual cause is the poor quality of the diffuser material - a better material that does not crack so easily would stop this in its tracks....... it’s the fine cracks that causes the hotspot that snowball into this problem.
Turn down your backlight level folks. Absolutely every TV I get for backlight replacement is set at 100%. No, it's not a fix. Nor is it excusing poor build quality, but it really does extend the life of the LEDs.
It's not just the curved model the none curved does it too it's those LEDs.
I found the problem (well you did) my (actually everyone who has this model TV) 48" JS9000 has this exact same issue.
I have the same problem with this model, I turned the backlight down when I first noticed the issue and so far have prevented the screen melt. some of the leds are burned out though. I think this is ridiculous for a less than 3 year old tv, Samsung should recall!!!
My white sheet inside the TV is destroyed which is also known as the Diffuser. Is there anyway i can get it replaced? or can order from somewhere online..
I have this issue as of three days ago. 7000 series flat. The bottom right of the screen is extremely hot and melted the screen. I called Samsung and they definitely didn’t seem to care! I was told to unplug it and I’ll need to bring my 55” tv 1 hour away to a repair facility! I’m Done with Samsung
I have a UN65KU7500, 2 years old that did the exact same thing.
Hi I have light difuser glass melted, its any chance to bu new one and where?thanks
I'm a Korean living in Korea, a country of Samsung. I'm ashamed of Samsung's dirty corporate ideology of deliberately covering up this issue.
It's not a country problem, it's a consumer problem. When people buy a TV, they look at screen size and price. The marketplace demands shortcuts be made to make them cheaper. A TV can be built for about 50% more that will last 5X as long, but consumers won't buy them.
Yes I have this problem as well and they are expensive so I demand a recall
I had the same problem with mine. UN65MU6290. A ton of LED's burned out and melted to the diffuser, along with the clips that held the led strips in. They were so brittle and stuck to the strips that they broke into about 30 pieces trying to remove them. Really disappointed in the tv.
Même problème sur une incurvé Samsung française, avez vous obtenu quelques choses de la part de Samsung ? Merci
I have had the same issue. My extended warranty just expired Feb 2020. I doubt they would try to help at this point even though this is a known documented issue with their tv's. The diffuser plate seems to be burned/melted on the sides because I can see the white areas on the sides of the tv screen when it's on. Does anyone know where you can buy a replacement diffuser plate (model UN65JS8500FXZA)?
I have the same exact model same same exact issue, any one know where to find the Light guide plate for these TV’s
Is the curved TV strip different than the flat one? is it curved like the tv somehow or it's the same in both models and can be flexed a bit?
The curve is gentle. The new strips are not curved but they are held down with double sided tape. Just start at one end and slowly lay the strip in - it will form to the curve if you do it right. You must remove 110% of the old double sided tape from the heatsink - any fraction of tape not removed will prevent the new strip from making perfect flat thermal contact with the heatsink. The new strips will fail within hours.
I have an UN65JS8500 that's 3 years old with the same problem. After reading some of the comments here I opened a ticket with Samsung. So far, they didn't say no to replacing it, we shall see....
Pls let us know the outcome. Thx.
@@PaulsTVCo Sorry for the delay, I was traveling. I got a call from a Samsung repair shop and they're coming out to fix it on the 7th, for Free! I'll come back when it's done and let you know the turnout.
So the guy came out, but not to repair it, just to look at what needed to be repaired. Was supposed to come back tomorrow to do the repair but I got a call today saying they can't get the parts so Samsung is going to give me a new TV. Now they have call call back with the details.
So they're offering me a $670 pro rated rebate, or, I could pay $470 for a UN65RU8000FXZA. Since they're selling on Amazon for less than 1k I'm going to take the rebate and buy the new one. All in all, I'm pretty satisfied since the thing is over a year out of warranty.
@@JayParisi did you need to show them your receipt? Did they say they wouldn't do it without proof of purchase?
Yes they need to recall the TV. Fire hazard.
I had the same TV and never has an issue with it. That owner probably left in on 24/7. I accidentally cracked mine though and I really felt bad for being broken as it was my parents as well. They weren’t too angry after all, but it definitely was an accident so they shouldn’t be angry. We hardly leave most of our TVs on 24/7 except the Vizio in the living room so we don’t expect burning LEDs.
There's no fire hazard. I've repaired hundreds of these and have never seen a fire.
@@guypatterson7334 I have seen pictures and Facebook post with fire. Mine also caught fire. Design flaw
@@jameshughes131 Pics? The internal diffuser melts, the LEDs eventually fail, and that's it. Without flame, burned parts are not a "fire".
@@guypatterson7334 it got so hot it burned. Charcoal edges. Smells like plastic. Actually the LEDs arnt even out. Just the diffuser puts off burning plastic smell with smoke. Had to go to er for heart palpitations.
Im having problem with backlight, how can I replace it
I have a UN55NU7300 curved, same problem with burned out LED’s and burned diffuser plate. I ended up cutting down the diffuser about 3/8” just past the scorched, bubbled area and replaced the LED strips. Can’t tell that the plate was altered but if it had gone further up the plate would have had to be replaced.
Do you have a RUclips channel, because I am facing the same problem and would really like to see how you do this properly.
Hi. Mines just melted the surface area a bit but enough to cause a brightness bloom in the area. When you trimmed your panel how did you cut it and did you wet sand it to a polish? I need about 2mm off mine. Cheers
HI, iam also facing this same issue...same model "UN65KU7500".hw to get LED strips..
Hello, this may sound a daft question but is the Lcd panel curved also or is if flat but bendy enough to match the curved frame? Thanks and great video
I have ssme model with the same issue the panel its blended to be curve
Hi Have-a-go RepairHero, i repair many TVs like this both from Curved and non curved and confirm most AV Boards, PSU and even Screen are the same but vary slightly depending on the series, like the NU and RU models are the same, and im sure the KU and MU series are the same. all burn the defusers also even though both sets have slightly different LED strips.
Curved TVs use the same flat LCD displays that are installed in the flat models. They are flexible enough to bend when put into the curved frame, but they are far more stressed and easier to fracture than their flat counterparts.
I have a samsung curve 55" tv and it is doing the same It gets a little warm but on the left side of my tv and there is white cloudy view. Model:UN55K6250
I have the exact same problem

Would turning down the backlights help this problem not to happen?
By turning down the backlights it may help for this problem not to happen within the first 2 years, but will it help for a long time? It's a good question.
Also, by turning down backlight it is not a fix. I would call it a PATCH.
If company provided the Dynamic Mode option, they should make their parts to last. That is my opinion.
@@PaulsTVCo Also, when the TV detects an HDR image, it automatically maxes out the backlight to 100% !!!
My 43 had burned out led when I got it for cheap. They were beginning to melt and distort the diffuser panel. When I installed the new strips I sort of offset them a little so they shone through the unburned bit, and the picture is not bad. A bit of light peeps up but very little. Only see it on a solid color screen. Crappy design flaw though. I keep them at 50% now. I wonder if you could shave down the edge with a sander so it's a smooth leading edge?? 2mm would do it but I've yet to try it. Anyone have any tricks or tips??
It won't help. I've dremeled out the burned crispies and it still leaves a very uneven screen. I stopped taking these in for repair.
I PULLED APART MY 65JS8000 YESTERDAY TO FIND THE SAME ISSUE
Mine did the same samsung replace the screen with a new one.
Paul we have also a curved samsung but we don’t have a dark sparks but one little white wipe when the screen light up clear… is that a LED problem ? The wipe is gone when the screen gets darker ….. best regards from Holland ✌🏽😀
If it's at the bottom of the screen, the diffuser is cracked. The white "wipe" is light leaking from the diffuser instead of staying contained inside.
Mine just did the same thing and it is UN75AU8000 the LED literally burnt, they carbonized and burnt some screen filters and everything I had bought the replacement parts, but decided to buy a new TV set and throw the other one away
I had this problem on my Samsung UN55KS9500FXZA curved TV
Most tv's backlights are overdriven by factory settings and pushing the leds over their limits. They won't last unless you decrease the backlight intensity to about 50%. Mine I got it to 40% and image still quite bright, so why to keep it at a 100%?
Yep. Whenever I do an LED replacement I change the value of the current sense feedback resistor to cut the display wattage so the customer can't crank it even if the setting is at 100%. No callbacks.
My Samsung 49” curved tv the diffuser sheet melted and the led backlight had also blown on the left side of the screen this is unacceptable as we are purchasing the tv in good faith’ I just wish that Samsung will let owners of Samsung tv with this problem were we can purchase the diffusers ??
have the same problem with a 43" 7500 series. This generation of Samsung curved monitors are just junk
Any idea why my Curve Tv picture is very dark?
Jacquelyn Scott . Some of the backlight leds are burning out. It won't be long before it will go completely dark. Basically same issue as presented in this video.
I stopped buying Samsung TVs after I had this problem. Been using LG C9 OLED since Feb 2020 and don’t have one regret. Also got the 5yr warranty this time. It’s OLED for me from now on. I paid less than I did for the Js9000 and the picture quality of OLED blows it away
the JS9000 was a 2015 set...I have the same issue, just on the sides, a white glow, about 2 inch spread towards the middle. 7-8 years is the life expectancy according to Magnolia at Best Buy-My backlight was 50%, my replacement is less than what I paid for the 2015 I'm wondering if that's why they stopped making the curved TVS...but hear it happens on flat panel too.
@@TheFlashyWeasel Yep. I got my Js9000 towards the end of 2015 on sale for 2,499.99 at Best Buy but only got the two year warranty and it started happening around 2.5 years. The small yellow spot started getting bigger and was making the screen really hot.
@@dlaroc The installer/setup guys said it was a panel issue-terrible light bleed on both left and right sides-top and bottom were fine. Either way, for what I paid for it (mine was 300 less than yours- I had rewards points plus received a TV mount/wire concealer). Either way, 7 yrs seems too short...my "tubed" and rear-projection TV's lasted longer.
LG OLEDs have a very high rate of screen failure. We do not recommend them to any of our customers.
@@ohger1 I’ve been using mine as a PC monitor since Feb 2020 and the only issue I’ve is a minor software issue where the side bar will pop up randomly. Other than that it’s been by far the best display I’ve owned. Not a sign of burn in at almost 9,000 hours. I’ve been pushing it since I have the 5 year Best Buy warranty that covers burn in. It’s a very good Tv imo.
OK, Samsung will replace the panel, including the Backlight, at no charge to the consumer. If you are a authorised Samsung service center, you need to tell the customer to contact Samsung customer service and apply for a 1 time courtesy repair. But inform the customer to make sure that they allow the customer to contact the customer relations management dept. This office is the only office a Samsung that has the authority to authorize the repair at no cost to the customer. We have done many of these and Samsung is the only company, that I am aware of, that will cover panel issues beyond the 1 year manufacturer's warranty.
When we got this set, it had no power. If customer will call Samsung with No power issue, they WON'T do anything. We had to open the panel, in order for us to see what is going on. In order for Samsung to fix/replace defective screen (as you say), customer needs to show the problem with the screen. How customer can do that if LEDS goes out and TV will not turn on? Good question, right? Samsung won't cover anything at this point.
As the service center, do we need to charge our customers to open their TVs and provide some pictures of the issue or we need to do this BIG job at no charge?
Check one of our videos (UN65JS8500 Samsung TV overheating/burning/ melting problem.). Customer called samsung and they did nothing for him. That is the reason we decided to make a video. Therefore, I will not agree with your last statement.
Wayne Mitnick, have you actually had experience of Samsung replacing the panel and backlight for free? And was the set out of warranty?
Same issue with my KU7500, backlighting just flickers now, and wont ever respond to the controls, $1000 and 2 1/5 years later wasted >.>. I remember when TVs lasted over 20 years with no problem, wtf is with these tech companies these days.
Simple, they make more money that way
@@russjg69 lolz I threw out that TV I had and got a LG 43" for less then half the cost :D, and has a better picture :O.
Sphoxros It’ll still break in a fraction of the time they broke a few decades ago. And the screen will crack from 1000 times less force than back then too
Instantly if it has music and they don't talk about it it sucks they don't know what they're doing
Our same model just did the exact thing...Not a good selling point Samsung.
Samsung should be embarrassed to put this TV to market. We bought the 55 inch curved set, had the screen replaced under warranty in the first three months, then in the third year an LED strip burned out, turning a quarter of the screen black! Garbage.
sAMSUNG ue65js9000 2 years TV same problem, they were so kind they are ready to repair for 3000 euro F...K samsung
@AndreyEliseev I replaced it with a QE55Q700T and the TV broke in 3 days lol Samsung really need to up their game and find some assembly companies that do a good job.
you can almost buy 2 TVS with that cost....
Samsung always a problem I buy lg
Never had a problem with Samsung TVs. LG Crystal LED TVs suck. Samsung’s even non QLED TVs beat LG LCD. But I am sure OLED is best, but I don’t want to deal with burn in displays because it’s permanent. I use QLED because it’s almost as good as an OLED panel.
LGs don't burn diffusers but have their own bag of issues with LEDs turning blue, burning out, and bad main board issues.
@@loudspeakertestsmorebyaida3804 I was told this can happen to ALL oled/qled panels, but Samsung seems to have more
