I am having the same power cycling problem that many others are having with the Samsung TV. I see that Samsung arranged for repairs of the problem at no cost. I would like to see what can be done for my TV. The critical issue is that none of the solutions I have read in your feedback solves the problem. The television doesn't stay on more than a second. In fact it never really turns completely on. The back light comes on and immediately goes off. Then the samsung logo in the center lower from lights up, then the TV powers off. I have a curved Model UN65KS8500FXZA, Serial Number <HIDDEN> Incidental to the power cycling issue, which is my focus right now, the sound often would not come onwould have to power off and go into cable tv mode to increase the sound. Then everything would seem to be fine. Before the power cycling started I had an issue with the sound being too low. So I had to do the above steps. Everything was fine and then the sound started stuttering loudly and finally went completely out and started cycling on and off.

Hello, I am glad to see that finally someone has received help from Samsung. My UN65ks8500F is doing exactly the same thing. It doesn't stay on long enough to try any of the suggested fixes. I am devastated because of the price I paid for what I thought was a top of the line TV. I have a smaller Vizio and a 3D LG which are both much older and still working as new. Do you have a number for the person or Dept. that finally helped you resolve your issue? Thank you in advance.
