The Vizio remote is important for the use of your Vizio smart TV, since you use it to navigate through the menu and various applications.

If the Vizio remote stops working, it can be due to low batteries, a blocked TV sensor, power residue of remote and TV, dirty power source, stuck memory of the remote, or issues with the TV itself.

In this article, we will offer a few tips on how to fix the remote, provided that the functionality is not affected by a flawed IR sensor.

4. Clear the way to the TV sensorhow to fix vizio remote control

The IR sensor of the TV is usually located either on the bottom left or bottom right of the TV. The sensor is very sensitive to anything that might block it, even protective plastic wrap that comes with new TVs.

So move anything that might be in front of the sensor, including books, picture frames etc.

Also, use a cotton swab with a bit of distilled alcohol to clean any impurities on the Tv sensor and also on the IR remote sensor ( the small lightbulb on the remote‘s front edge).

5. Reset Remote to Clear the Memory (for Universal Remotes)clear memory universal remote

  1. Press and hold the Set or Setup button. Release the button LED on the top of the remote light blinks twice.
  2. Type in the reset code of your remote, most Vizio universal remotes have a reset code of 981 or 977. You can also consult your remote’s manual to find the reset code.
  3. Again, the LED should flash twice. This means that the memory has been cleared and any firmware issues should be resolved.
  4.  Switch it back to the TV using the button at the bottom of the remote and see if it works.

If the problem persists, the problem might be related to the IR sensor. The only solution here is to replace it altogether or to change the sensor.

For the first solution, check Vizio’s offer for remote controls, as they sell various models for all TVs. Also, contact Vizio technical support at 1 (888) 849-4623 for more information.
