Billions of people don’t know the secret of the TV remote!

1. Disassemble the controller: Use a small screwdriver or plastic card to open the controller without damaging the edges.
2. Cleaning internally:
   • Separate the circuit board and the rubber membrane.
   • Clean contacts with isopropyl alcohol and a cotton swab.
   • Reinforce the contacts with conductive paint if they are very worn.
3. Check the IR LED:
   • If it doesn’t emit light (verifiable with the camera), you can replace it with one from an old controller.
4. Close and Try:
   • Make sure the parts are properly placed.
   • Test the control on the TV.

Additional Tips

• Keep controls away from moisture: Avoid leaving them near glasses, plants or outdoors.
• Don’t use too much force when pressing the buttons, as it speeds up wear.
• Have a universal controller as a backup while you repair the main one.
• Check the control if you have several to avoid confusion (especially in homes with many devices).

Conclusion

With simple materials and a little patience, you can fix many of the typical remote control problems without resorting to technical services. This knowledge not only saves money, but also reduces unnecessary e-waste. A basic skill that can be very useful in any home.
