The projector shows as “warming up” well after all the other projectors have already started. When looking at the crestron connection menu in the hidden service menu, it shows a green rectangle for the status.

First disconnect the projector's power cord for a minimum of 3 minutes. Double-check that the crestron says that the projector is “disconnected”. Plug the projector back in. See after about 5 minutes, the green rectangle appears again next to that projector.

In the regular projector menu, attempt to click “off” and “on”. You may see a flicker on the left side under “power” where it says it is warming up. There is no other GUI indication on the crestron you'll see. Next wait to see if the projector begins to light up.
