Is there a trick to the power button? I have a new 70″ ActivPanel that I love. We’ve got about 3 in the building right now and on all of them there seems to be no rhyme or reason to how long it takes to actually get them started (power light green). It seems like if I hold the power button down for 15-20 seconds it sometimes starts, but sometimes it takes a longer or shorter amount of time. Also, the remotes seem to be about as useful and require very close proximity to work. If this just happened with my board I would consider it a technical error, but all of ours seem to work (or not work) this way.
