Samsung TV brightness constantly changing

[Evonian]

Hi 

I have a Samsung ks7000 and it's now about a 2 years old. I've notice that there is a very subtle change in brightness every 2 seconds it's worse on the left side. Even if I pause the TV it still does it or if I do the picture test it still does it. All my eco settings are off and I've tested other HDMI ports. It is very subtle but I notice it alot in dark scenes almost like a flickering. I'm not sure if I should send it in or is there some sort of fix? It is on firmware version is 1241

@Evonian: Please can you try going to Settings > Picture > Expert Settings > Smart LED, and disable this feature if it's active. Also, go to HDR+ Mode and disable it to see if this helps, as both settings finely adjust the brightness and contrast, depending on the scene. Let me know how you get on.

Hi Andrew, thanks for the reply sorry getting back to you so late I thought I would get notified. I do have all those settings off, it seems to related to the hardware (i think) as it doesn't matter which HDMI channel I choose with all setting turned off, and also it occurs when I pause the image so nothing is happen with picture. If i do the picture test the brightness is still changing constanly it is very subtle but also noticeable and consitently every 2 seconds. Not sure if I should send it in and if this falls under warranty? Thanks

Hey Evonian. 

Found your post by googling. I have a LG 49UJ6300-SA with the same issue. Exactly each 2 seconds, the image saturation changes. I've reset my TV to factory defaults and the issue still persists. It seems to be a hardware issue, and no specific to the manufacturer. Did you found a fix for this issue?

Hello

Have the same issue on UE55KS7002. Brightness is constantly changing every 2sec. Especially noticeable in dark scenes. All eco settings are off. Weird.
