How to stop my Smart TV flickering or dimming

Last modified : Nov 20. 2018

If your Samsung Smart TV is having trouble displaying images properly, either flickering or dimming, there are a couple of things to check. See the dropdowns below for information on disabling the Eco Sensor. Eco sensor is a function that will adjust the screen brightness depending on the light in the room. The Energy Saving feature of some TVs will likewise affect the brightness of the TV screen. 


If the screen on your TV flickers to black rather than dimming, particularly only on one source; check that all cables are connected to your TV securely.


If your TV screen is flickering or dimming sporadically, you can try to disable some of its energy efficiency features such as the Eco Sensor or the Energy Saving feature to keep the brightness level consistent.
