LG TV insists on turning itself off

We’ve got an LG TV being used in the office for displaying system information from a Raspberry Pi plugged into the back. The Pi is powered via USB from the TV.

We’ve used the timer to get it to switch on at 6am on weekdays, off at 5:45pm, reflecting the hours people are in the office.

It was consistently switching itself off at the wrong time, exactly two hours after it came on.

Turns out it’s a long-running bug in LG televisions.

In the forum, some found if they could get into the service menu, they could remove the 2 hour sleep setting.

Others found setting it to “hotel mode” would disable all timers – in our case this would waste a lot of power though.

    Unconfigure the tv’s timer and plug the set into an old fashioned mains timer 😉
