- Sleep Timer: Turns the TV to standby mode after a preset length of time.
- ECO
- Presence Sensor: When the sensor detects no motion in front of the TV for a certain period of time, it turns the picture off automatically, while leaving the TV sound on. Additionally, if no presence is detected after 30 minutes in picture-off mode, the TV will switch to standby mode. In some cases, it will turn off the TV if you are too close to the TV or the sensor is blocked by an object.

- Auto Shut-off: Turns the TV off when no input signal is detected for a certain period of time.
3. Make sure the AC power cord (mains lead) is properly plugged in
- If your TV has a power cord (mains lead) that can be removed, make sure that it is firmly plugged into the back of the TV.
- If the TV has a separate AC power adaptor, check the connection between the adaptor and power cord (mains lead) as well.
- Make sure that the power cord (mains lead) is properly plugged in to the AC outlet on the wall.
- Remove any power strips, surge suppressors, or other similar devices and plug the TV directly into the AC outlet on the wall to verify that these additional devices are not causing the issue.
- Try a different AC wall outlet and make sure the outlet is not controlled by a switch that is turned off.
4. Check for remote control issues
Remove the batteries from the remote and check whether or not the issue persists. This tests whether the remote is malfunctioning, rather than the TV.
Notes:
- If you are using a multi-function remote in addition to the supplied one, check it too.
- Covering the remote control sensor of the TV is also a way to check whether the issue occurs. Refer to the manual for information about the location of the remote control sensor. However, you cannot verify using this method if the issue is caused by a remote control which is not an infrared type, such as the Touchpad Remote Control.
5. Check for issues with externally connected devices
Disconnect all external devices (USB, LAN, HDMI, antenna, etc.) from the TV except the AC power cord (mains lead). Verify that external devices are not causing the issue. If the issue is resolved, reconnect the devices one at a time to find the device causing the issue.
6. Turn off the TV's Wi-Fi function
If your TV has Wi-Fi capability, temporarily disable it to help determine if the issue is related to the network connection.
7. Perform a power reset
8. Reset the TV to the original factory settings
