I have the same issue with a JS8500. "bleeding black blotches from the edges" is a good way to describe it. I sent pictures to Samsung. Curious what their response will be. I'm reading around 158 degrees F on the top left edge. I'm worried there might be a catastrophic failure (smoke, sparks, etc...) as other people have mentioned in the community.
I got a Samsung J5200 50"-Class Full HD Smart LED TV in July 2017, there where cheaper options but I went for Samsung thinking of quality but as many other people in here it overheated and a corner of the tv melted, it has sound but a black screen, this happens only a year and a half later, it is not only a money concern but a safety one, this tv is a fire hazard, I leave this Tv on when I leave for my dog, I'm glad this happened while I was home because it was really hot; I sent a PM to SamsungCole with all the info requested, I need a solution.
My Samsung UN50J6300 Smart TV apparently overheated today and now the screen is black. I had no idea there have been issues of this nature from Samsung TVs or I would not have purchased it three years ago. I called Samsumg today, but of course the representative could not help. It is a shame that the appliances of today are made of such poor quality and craftsmanship. One previous tv I owned lasted approximately 25 years and another one I still use is about 20 years old.
Furthermore, I purchased three new Samsung appliances for my kitchen. Two of those appliances have already had issues. In fact, the microwave will need to be replaced or repaired with a $150 part. I will NEVER buy a Samsung product again. It is ridiculous that companies would manufacture such crappy products and not expect people to spread the word or search online for information.
We just had the same issue last night. The TV is 6 years old, but I'm still really disappointed in this hardware. Not only is it crazy for a high end TV to fail after 6 years, but this failure mechanism is really scary! This could've started a fire in our house if we hadn't been sitting right there!
I have a Samsung 50" Class Smart LED TV - UN50J6200 TV and it was purchased in October 2015. The lower left hand corner melted and the TV is inoperative. I believe this happened last night with the TV turned OFF while the tV was fine in the morning hours of yesterday when last used.
This is a definite fire hazard and after researching this on line this morning, I can see it is a common problem and Samsung is aware of it. This TV and other models affected should be recalled. I want a refund or exchange (non-fire hazard model please) TV. That's only fair seeing you (Samsung) have known about this issue and failed to warn consumers or recalled your defective product.
