Diagnose and Fix the Real Problem

Before fixing the TV remote sensor, let us perform some basic tests to sort out the real problem. So, we can fix the issue in the right manner.

1. Check the Remote Signals

2. Change the Remote Batteries

The second thing you need to do is change the remote batteries. The one reason behind a non-working remote sensor is expired batteries. Another reason is the remote is locked and not working. So, you should reset it.

You can do this by removing or replacing the batteries. Open the back cover of your LG TV’s remote control. Take out the batteries and insert the new pair. Be sure to insert the batteries in the right position. Now, check whether your TV sensor works or not.

3. Examine the Remote Battery Terminal

Another cause of non-functional remote sensors is defects in the remote. You have changed the remote batteries but still, the sensor is not working. You should examine the battery terminal.

Look for the rust in the battery terminal area. Disassemble the remote and confirm that all things are connected between the remote board and terminal.

4. Try a Different Remote Control

This is a very easy diagnostic test. All you need to do is just take another LG remote. Make sure that this remote is working well with another LG TV.

Now, operate your TV through it. If this remote works with your LG TV then the older remote is defective.

Another test is to use your existing remote with another TV. If it does not work with a different LG TV, it is confirmed that the remote is faulty.

You have to replace the remote and that’s all. But, if the new remote does not work with your LG TV then the fault lies in the TV sensor.

Sometimes, the TV remote sensor stops working because of some electronics nearby. There may be something that is blocking the signals. So:

  • Turn off fluorescent lights and LED bulbs. They may also interfere with the remote sensor. Make sure that nothing is placed in front of the TV remote sensor.
  • Clean the sensor and remove any stickers placed on it. You can clean the remote sensor with a cotton swab soaked in distilled alcohol.
  • Go closer to your TV and operate it from a minimum distance. Maybe you are operating it from a large distance.
