I thought that was the most likely place. Because of my cheap DIY mount, taking it down is not the easiest thing so I was trying to avoid that for as long as possible. Thanks for the box suggestion, I do still have it.
I'm hoping that the turnaround will be no more than two weeks, is that wishful thinking? I waited on hold with Infocus for about 15 min, earlier and couldn't wait any longer, I'll try again.
