Smart TV screen flickering or flashing on and off
TV flickering is caused by a loose HDMI cable, the wrong picture mode setting, or refresh rate mismatch between the TV and your device you are watching. Check the HDMI cable first, then change the picture mode from dynamic to standard. This fixes most flickering.
Screen flickering on a smart TV happens when the image refresh rate or HDMI connection is unstable. A loose HDMI cable, wrong picture mode, or incompatible resolution can all cause it. We will check the cable, adjust picture settings, and make sure your TV is set to refresh at the right speed.
