Why does my LG 55LM5800 LCD TV turn off suddenly?
There are a few reasons why your LG LCD TV might be turning off unexpectedly. One possibility is that the power supply is unstable, so check your power control settings. Also, the Auto sleep feature might be enabled in the Time settings. Finally, the TV is designed to turn off automatically after 15 minutes of inactivity if there's no signal.
How to fix LG 55LM5800 remote control not working?
If you're having trouble controlling your LG LCD TV with the remote, start by checking the remote control sensor on the TV itself and try again.
