Backlight problem

[Chieff666]

I have a UE75NU8000 tv.

The problem is when i change the backlight in the settings to 0 or 50.

There is no difference. The tv is now 4 months old. I remember when i buy the tv and change it. There whas a huge difference. I already called the callcenter. This person on the telephone had the controll of my tv and did a full reset. The problem still exist.

Can anyone help me?

@Chieff666: Can you try going to Settings > General > Eco Solution > Ambient Light Detection > Off > Minimum Backlight > Off

Furthermore please go to Settings > Picture > Expert Settings and adjust the Contrast, Brightness, Sharpness, Colour and Tint to see if you are able to customise the picture to your preference in this manner. Please do this with any external devices disconnected to eliminate the possibility of external interference.

Yes. I tried it everything.

Settings > General > Eco Solution > Ambient Light Detection > Off > Minimum Backlight > Off

Also after setting Contrast, Brightness, Sharpness, Colour and Tint to full and 0 settings the backlight still dont work. I tried it with normal tv, netflix, ps4, smarthphone casting to tv.

Its all the same

What i did with my problem is go to secret setting samsung you can find it on the ethernet. And i change the local dimming to 1 or 2. Now its back normal. Only with netflix sometimes the blacklight changes when theres a dark scene. But its a samsung tv problem in general. What you also can do is do factory settings in the secret menu. IMPORTANT!!!!! Dont mess with other setting in the secret menu. When you do something wrong. There is a chance you get a black screen or anything and youre broke your tv.

My Samsung tv has started turning on a blue tint screen whilst on standby, turn on, off and it goes away. It's the second time it's started doing this. I read some where that the TV does this when doing updates, if so it's staying on. Maybe an update changed a setting in the screen menu settings. I think I may have changed a screen setting before that stopped it but can't remember. iam sure it's settings or software related.
