We recently got 4 of these 42LS5700 in our office here (I'm the IT guy) for displaying presentations throughout the office spaces.
I plugged in a laptop, got it all set up, and configured the TV to turn on at 8am, off at 6pm.
Well, turns out they turn themselves off after two hours. I just called into support and it's a "safety feature", and non-configurable.
I'm guessing this is not something that has come up for y'all in normal A/V usage... but I wanted to post and ask if anyone has run into this, and if so, do you have any suggestions for a workaround? What is necessary to reset this timeout, I wonder... is only the movement of the remote control that will?
I wonder if pinging the network interface might be sufficient (I doubt it).
Can these things be turned on/off via the network? I could script something to turn them on every 2 hours...
Any ideas!? I don't want to have to box up and send all 4 back, even if they would be accepted by the vendor!
