Why does my LG LED TV turn off suddenly?
Your LG LED TV might be turning off suddenly because the power supply is interrupted; in this case, check the power control settings. Also, check if the Sleep Timer or Timer Power Off is activated in the TIMERS settings. If the TV is on but there is no signal, it will turn off automatically after 15 minutes of inactivity.
What to do if my LG 43UH668V remote control is not working?
If you cannot control your LG LED TV with the remote, check the remote control sensor on the TV and try again. Ensure there are no obstacles between the remote and the TV. Also, check if the batteries in the remote are working and properly installed.
What to do if my LG 43UH668V has no image and sound?
If your LG LED TV has no image and produces no sound, first check if the TV is turned on. Then, verify that the power cord is properly connected to a wall outlet. To ensure the wall outlet is working, connect other products to it.
