Why is HDMI not working on Vizio TV?
If the HDMI port on your Vizio TV is not working, the most effective solution is to perform a hard restart by unplugging it from the power source. Alternately, you may need to replace the HDMI cable or port, change the display settings on the device, update your firmware, or perform a factory reset.
Why does my Vizio TV say no signal when HDMI is plugged in?
