If your TV remote looks fine but still doesn’t work, the issue might be with the infrared (IR) sensor. This tiny LED at the front of your remote sends signals to your TV—and when it fails, your remote becomes useless. Here’s how to fix it:
1. Test the IR Sensor
Point the remote at your phone’s camera and press a button. If you don’t see a flashing light on the camera screen, the IR sensor isn’t working.
2. Replace the Batteries First
Before diving into repairs, make sure you’ve inserted fresh batteries.
3. Open the Remote
Use a small screwdriver to carefully open the remote. Be gentle to avoid damaging the casing.
4. Inspect the IR LED
Look for any obvious damage or misalignment. If it’s bent, you can carefully straighten it. If the solder looks cracked or loose, it may need reflowing.
5. Re-solder or Replace the IR LED
With a soldering iron, reattach any loose pins. If the LED is completely dead, you can purchase a replacement IR LED and swap it in.
This type of repair requires patience and a steady hand—but it can save you the cost of a new remote.
