If the image appears slowly when you turn on your LG LCD TV, this is normal as the image is muted during the startup process. However, if the image doesn't appear after a few minutes, try unplugging the TV for 30 seconds and then plugging it back in.

If your LG LED TV is turning off suddenly, check the power control settings to ensure the power supply isn't interrupted. Also, verify if the Auto sleep feature is activated in the Time settings. If there is no signal while the TV is on, the TV will turn off automatically after 15 minutes of inactivity.
