Why does Samsung TV screen turn dark while watching?

Last Update Date : Apr 03. 2019

There may be several possible reasons that can cause dark image in your Samsung TV screen. Screen can become dark due to bad broadcast transmission.

Some major causes for dark image are mentioned below : 

● It may be caused by changed picture setting.

● If all channel has different brightness of screen, it would be due to different broadcast programs.

● If the screen mode is set as a movie mode, the screen might be dark.

● Screen mode is a function by which users can adjust the brightness of screen.

● You can choose custom mode, standard mode, natural mode, or movie mode. Change the screen mode to the standard mode.

● The screen may be dark if it is under power saving mode. Turn off the power saving mode. CLICK HERE to know how to turn off power saving mode in Samsung TV.

● The Ambient Light Detection function (also called ECO Sensor on some older models) measures the light in the room and changes the screen brightness automatically to reduce power consumption. The screen will be brighter in a brightly light room and darker in a dark room.


The method for turning this function on or off will differ depending on your model

2016 models or older: System > Eco Solution > Eco Sensor > select On or Off

2017 models or newer: Settings > General > Ambient Light Detection > use the slider to turn on or off
