What to do if my LG 42LS3400 has no image and sound?
If your LG LCD TV isn't showing an image and there's no sound, first ensure the TV is actually powered on. Next, verify that the power cord is securely connected to both the TV and the wall outlet. Lastly, test the wall outlet by plugging in another device to confirm it's working correctly.
Why does my LG LCD TV turn off by itself?
If your LG LCD TV is turning off unexpectedly, you should first check the power control settings to ensure the power supply isn't being interrupted. Also, verify that the Auto sleep feature is not enabled within the Time settings. Lastly, be aware that if the TV doesn't receive a signal for 15 minutes while it's on, it will automatically shut off.
How to fix an LG 42LS3400 remote that is not working?
If you're unable to control your LG LCD TV with the remote, start by checking the remote control sensor on the TV and try again. Make sure there are no obstructions between the remote and the TV. Also, ensure the batteries in the remote are working and correctly installed.
