I have had the Samsung A77Q 4k 65'' for around 26 months, and as much as I love Samsung but this is a big problem.
I bought the TV when it was relevantly new and I did not have a problem with it. But after a few months I noticed that at a part of the right became a little brighter then the other parts of the screen.

I thought that it was not a big problem and it was still okey to look at. But after a few more months I turned on the TV and it was getting darker at the left side of the screen. A few days later and now is the screen almost all dark and its almost impossible to see anything.

I went and reported the problem to the store we bought it from and they started saying that it would cost a lot to get checked out.

I do not know what to do because the TV was not cheap and now they are telling me that it will be even more expensive to get checked out by a expert. I will contact my insurance company and see what they tell me and if that doesn't work I will get the TV checked out by someone. I guess I will have to pay even more for something I thought would last me at least 3 years but even that it couldn't do.

As I said before I like the Samsung company and I like your products. But I do not get why the TV screen went out so quick when I had I different Samsung TV for almost 11 years and nothing happened to it but this new one just gave up. I have had your phones for over  10 years now and they all are great, so the tv must have been a faulty one and yes I have tried trouble shooting it and it did not work.
