I show up at a client's house at 4:00 because the bedroom tv has sound but no picture (audio is through the DA system, and video is through an hdmi matrix). I find the tv isn't turning on. Closer look, the IR flasher isn't working. I've seen this happen before with Elan and go to reboot the processor (I do this from in the configurator). When the processor comes back up... its factory defaulted. Yep... completely clean slate.
