Cut a piece of opaque tape or a small piece of paper or cardboard large enough to cover the IR sensor completely. If using a tape, make sure it’s wide enough and make a neat cut for a clean finish.
Step 4: Apply the Blocking Material
Carefully place your prepared tape or cardboard over the IR sensor, ensuring it covers the sensor completely. Press down firmly to ensure there’s a solid seal. If you’re using tape, make sure it’s applied snugly so that no light can penetrate.
Step 5: Test the Functionality
Now that you’ve blocked the IR sensor, it’s time to test its effectiveness. Try using the remote to control the TV. You should find that it no longer responds to commands, signifying that the sensor is effectively blocked.
Reversing the Blocking Process
In case you need to reverse the process, unstick the tape or remove the cardboard. You can remove any residue left behind by carefully cleaning it with a gentle cleaning solution and a soft cloth.
Alternative Methods of Temporarily Disabling the IR Sensor
While blocking the IR sensor directly is one approach, there are other methods to temporarily disable it without physical obstruction.
Using Remote Control Options
Some modern TVs have settings that allow you to disable the IR sensor from the TV’s system settings. Look for options like “Remote Control Settings” or “Accessibility Settings” in your television’s menu.
Using a Universal Remote
Universal remotes often have features that allow you to program or set specific commands, including disabling the control of certain devices.
