Why does my LG 42PN4500 Plasma TV turn off suddenly?

If your LG Plasma TV turns off suddenly, first examine the power control settings to ensure that the power supply isn't being interrupted. Also, check if the Auto sleep feature is enabled within the Time settings. If the TV doesn't receive a signal while it's on, it will automatically shut down after 15 minutes of inactivity.
