A common problem with TV remotes is that they stop working even when the batteries are not dead. Many people try tapping the remote, and surprisingly, this can fix the issue.
One explanation is that oxidation forms on the battery contacts over time. This creates a layer that blocks the flow of electricity. As a result, the remote cannot send signals to the TV.
Tapping the remote may dislodge this oxidized layer or improve the connection between the batteries and the metal contacts. This allows electrical current to flow again and restores the remote’s function.
