2. Check Connected Cords

Your Samsung smart TV may flicker due to loose or damaged cables connected to it. So check all the cables connected to your TV such as an HDMI cable, USB cable, etc. If the Samsung TV screen flickers while connecting to a particular device like PS5, or Fire TV stick, then the issue could be in their cable. A good practice is to disconnect and reconnect the cables. You should also try applying more pressure while reconnecting the cable. Furthermore, try connecting the cord using a different HDMI/USB port on your TV, or even better try a different cable itself.

3. Change the Video Source

If your Samsung TV is connected to an external device like a USB dongle, or streaming device (Roku, Fire TV, etc.), there are chances that the problem is in the external device. Try changing the video source to see if the issue is fixed. Tip: Learn how to view photos from Android or iPhone on Samsung TV.
