If the remote control for your LG 3D TV isn't working, start by checking for any obstructions between the remote and the TV. Make sure you are pointing the remote directly at the TV.

If problems persist, install new batteries.
What to do if my LG 3D TV has no picture and no sound?
If your LG 3D TV shows no picture and produces no sound, start by verifying that the TV is powered on. If it is on, try switching to another channel, as the issue might be with the broadcast signal. Also, check that the power cord is securely plugged into the wall outlet. Check your antenna direction and/or location. To ensure the outlet is functioning correctly, test it by plugging another device's power cord into it.
Why does my LG 3D TV suddenly turn off?
Your LG 3D TV might be turning off suddenly due to several reasons. Check if the sleep timer is activated. Also, examine the power control settings. If there is no input signal, the TV will automatically switch off after 15 minutes to save power. If a corrupted file was played from a USB device, the TV may turn off. Also, make sure the screen off mode of the energy saving menu is disabled. It is also possible that the power was interrupted.
