Causes
- Energy Saving mode

Energy Saving Mode
When your TV’s energy saving mode is turned on, your TV’s screen might blink while displaying power-intensive content on screen. Such content expends power while your TV tries to save it causing your screen to blink.
Ambient light detection
Samsung TV’s come with an ambient light detection feature – meaning that your TV will detect the amount of light in your environment and automatically adjust the brightness of the screen.
Sometimes, due to either a temporary glitch, or constantly changing ambient lighting, your TV’s screen might blink.
Backlight settings
The backlight option on your TV changes the intensity of the light source of the TV. If you’ve set the settings to maximum backlight, your TV’s screen might blink because of the power load it puts on the device.

What does it mean when my Samsung TV’s power light is blinking?
When your TV’s power light blinks, it means that either there is some issue with the power supply or your HDMI cable isn’t connected properly.
Causes
- Issues with the power supply.

Issues with the power supply
If your TV’s power light keeps blinking, it is an indication that your TV isn’t receiving a sufficient/ stable supply of electricity. This usually happens when your TV’s power cable is loosely attached to the socket.
When this happens, unplug your TV’s power cable from the socket and re-plug it securely.
Loose HDMI Cable
When one of your HDMI cables are loose, they might send unstable, interrupted signals to your TV’s main board and cause the power light to blink continuously.
When this happens, unplug all connected cables from your device, clean their ports if there is a need, and then re-plug them firmly to the TV.
