Step-by-Step Repair

  1. Step 1 of 5
    1

    Replace the batteries

    Put in fresh, name-brand batteries. Even if you replaced them recently, try new ones — cheap batteries can die quickly. Make sure they're inserted in the correct orientation (+/-).

  2. Step 2 of 5
    2

    Clean the IR sensor

    Clean the IR emitter on the front tip of the remote with a cotton swab dipped in isopropyl alcohol. Also clean the IR receiver on the TV (usually a small dark spot on the bottom front edge).

  3. Step 3 of 5
    3

    Test the remote with your phone camera

    Point the remote at your phone's front camera and press a button. If the remote is working, you'll see a purple/white flash through the camera. If you see nothing, the remote is dead.

  4. Step 4 of 5

    Check for obstructions

    Make sure nothing is blocking the line of sight between the remote and the TV's IR sensor. Sound bars, decorations, or even a dirty sensor window can block the signal.

    Re-pair the remote (for Bluetooth/RF remotes)

    Some smart TV remotes use Bluetooth, not IR. Check your TV's settings for a "Pair Remote" option. Hold the pairing button on the remote (usually for 5+ seconds) to put it in pairing mode.

If That Didn't Work

  • Battery contacts corroded inside the remote
  • Button contacts worn out from heavy use
  • TV's IR receiver board failed

When to Call a Professional

If a new remote doesn't work either, the TV's IR receiver board may be faulty. This is an inexpensive part ($10-$20) but requires opening the TV. A universal remote ($10-$15) is often the easiest solution.
