  If you cannot control your LG TV with the remote, it could be due to several reasons. First, ensure you are within 10 meters of the TV and that there are no obstructions. Communication failures can occur if you are outside the coverage area or if obstacles are present. Devices operating on the 2.4 GHz frequency, such as microwave ovens and wireless LANs, may also interfere. Additionally, a wireless router (AP) within 1 meter of the TV can cause issues. Check the remote control sensor on the TV, ensure there are no obstacles between the remote and the TV, and verify that the batteries are working and properly installed.

  Your LG TV might be turning off suddenly due to a few reasons. The power supply could be interrupted, so check the power control settings. Also, the Automatic Standby Timer in the TIMERS settings might be activated. Additionally, if the TV is on but not receiving a signal, it will automatically turn off after 15 minutes of inactivity.
