With time manually set, we configured all sets to power off at 9:30pm daily and back on mon - sat at 7am. Each morning, the sets are on as configured. at 9:30am, each set powers off. We have confirmed that the time is properly set, and that the timer is set to PM, not AM. Still, the sets power off 12 hours before design.
Testing has confirmed that the feature works if set to go off one or two minutes from current time. Same with powering on. If it is 3:45pm and I program it to turn off at 3:46, it complies.
Yesterday, since our signage units have the abilty to power on/off thorugh HDMI (but the LG TVs don't listen to the power ON signal, long story) I configured the signage to power the unit off at 9:30pm and the TV turns itself on at 7am. This solution worked for one day. The set was confirmed off at 9:30pm, and it was on in the morning when the workforce arrived. However, the next time I walked by a set, it was off. These sets are mounted out of reach, and I have all remotes. Also, this is our off-season, so we have nobody here to interfere.
Has anyone had or heard of any reported problems with the built-in timers? Perhaps the TV has anti-burn-in tech that turns it off after so many hours of operation? Perhaps an inability to read PM or AM? I notice the TV shows military time when powering on, despite the fact that the timers are using 12-hr AM/PM time format.
Any suggestions would be appreciated.
Yes, I can confirm there's a problem with the timer. I have the 42LD550. The timer will work to turn the set off and on at my designated times. However, it will also shut the TV off at a time later that I didn't choose.
For example, I set the timer to turn the set off during the day, from 8:00 am when I'm at work, and back on again when I get home at 5:30 pm. This works; I've seen it go off before I leave and it's on when I get home. However, at 7:30 pm, the set turns itself off. However there's no secondary timer, and I haven't changed the timer from its orginal setting.
My set has the latest firmware 08.03.06. This has been an issue on previous firmwares since I purchased it in February of 2011.
Although I haven't contacted LG about the timer issue, I did contact them last year about the clock not automatically adjusting for Daylight Savings Time and the Automatic time setting not working. Here is LG's response:
The clock time is not determined or controlled by your internet connection. The time is adjusted automatically, if you have an antenna or straight cable. The time is adjusted by information from a designated broadcaster. If you use a cable box or satellite receiver, the time will not adjust automatically, but have to be adjusted manually.
