I have a new Samsung tv and when starting it up you can see that the back-light is very uneven but when on AV, HDMI and Free view, the backlight is perfectly fine (apart from some uneven lit LED areas which is barely visible unless you move your eyes slowly across the screen). When I go onto the smart mode and there is anything black, you can clearly see the unevenly lit areas but I don't use smart TV anymore. The only thing that bothers me about it really is when going into smart setting and watching movies on Love Film. Is it a common thing that can occur on any LED lit TV?
