1. Use Your Smartphone Camera

Most TV remotes use infrared (IR) signals that are invisible to the naked eye, but visible through most smartphone cameras.

Steps:

1. Open your smartphone camera app.


2. Point the remote’s IR LED (the front part) at the camera lens.


3. Press any button on the remote.


4. Look at your phone screen:

If you see a flashing light, the remote is working.

If no light appears, the remote may have dead batteries or be broken.

2. Check the Batteries

Remove and reseat the batteries.

Replace old batteries with fresh ones.

Try again with the camera test.

3. Try Another Device

If your remote can control multiple devices (like a universal remote), try it with another device to confirm functionality.


---

4. Use an IR Sensor Tester (Optional)

Some electronics stores have IR sensor testers specifically for checking remote signals.

Final Thoughts:

This is a simple DIY method to check any TV remote using your phone — no special tools needed. If the remote still doesn’t work after confirming signal output, consider replacing it.
