Why does my LG 42PA4500 Plasma TV turn off suddenly?

If your LG Plasma TV suddenly turns off, first examine the power control settings to ensure the power supply isn't interrupted. Then, verify if the Auto sleep feature is enabled within the Time settings. Also, be aware that the TV will automatically shut down after 15 minutes of inactivity if no signal is detected while it's on.
