Samsung repair replaced main board. Problem is still there unfortunately. In addition, since the main board replacement there are pixels in my screen a straight line of them when using the smart hub apps. Repairman is being dispatched again. Will update on next part they replace. I promise you they will replace every part in this TV until it's fixed. I have never owned a Samsung product that has behaved liked this.
