The LED (light-emitting diode) can be found at the top of the Samsung SolarCell remote, right above the circular direction pad. It explains the status of your remote. It will let you know when the remote is disconnected, when it needs a charge, and when charging is in progress.
No LED showing
Sometimes the best LED, is no LED at all. No LED means that the remote and the TV are properly connected through Bluetooth.
The LED blinks twice
If the LED blinks twice when you press a button on the remote, this means that the Bluetooth connection between the TV and the remote has been lost. Because the remote also operates through an IR transmitter, you will still be able to change the channel and the volume. If you want to use smart features like voice navigation, the Bluetooth connection will have to be restored. Please refer to our guide, Connect the Smart Remote to your TV.
The LED remains on for 5 seconds or more
If the LED stays on for at least 5 seconds after you press a button on the remote, this means that the remote's battery needs to be charged. A charging guide will appear on the TV screen once the remote's battery level is at 50%, then again at 10% or less.
Note: The remote control's LED will stay on for 5 seconds every time a button is pressed when the remote's battery is at 10% or less.
The LED stays on constantly
If the LED is staying on, this means that the remote is charging successfully. The LED will turn off once charging is complete.
