We are attempting to start up several DLP LightCrafters connected to power only. Two of the five ordered turn on, show the initialization page that displays the LightCrafter logo and a loading bar, load almost to the end of the bar, and then freeze. One of the two defective units is unresponsive to the power button when it reaches this point. We are wondering how to troubleshoot this problem. Specifically, we were thinking there might be a way to overwrite the preinstalled software on the projector and that there might be some basic package we could install in its place available from TI or somewhere else. Any suggestions would be appreciated. Thanks!
