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.
