Samsung TV is flickering or dimming

Last modified : Aug 09. 2019

If your Samsung Smart TV is having trouble displaying images properly, either flickering or dimming, there are a few things to check. See the dropdowns below for information on disabling the Ambient Light Detection. The Ambient Light Detection is a function that will adjust the screen brightness depending on the light in the room. The Energy Saving Modefeature 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.

 

Before going through the troubleshooting tips below, use Start Picture Test to determine if the problem is caused by the TV. The Start Picture Test displays a high definition picture you can examine for flaws or faults.

 

If your TV screen is flickering or dimming sporadically, you can try to disable some of its energy efficiency features such as the Ambient Light Detection, Minimum Backlight, Energy Saving Mode, or Motion Lighting to keep the brightness level consistent.
