If your LG TV powers on or off by itself at specific times, a Power On/Off Timer or an inactivity auto power-off feature may be enabled. Check the TV time settings and turn off any timers that are not needed.
This symptom is often caused by scheduled Power On/Off timers or automatic power-off behavior after the TV turns on by timer and no one uses the remote for a set period. Incorrect time settings can also make timers trigger at unexpected times.
If a Power On Timer or Power Off Timer is set, the TV can turn on or off at the scheduled time. This can look like a repeating power issue when the schedule repeats daily or on selected days.
On some models, when the TV turns on using a Power On Timer, it may turn off automatically after a period of inactivity (for example, 2 or 4 hours) if there is no remote control input.
If the current time is incorrect, timer events may trigger at unexpected times, which can be mistaken for a malfunction.
