Ron,
Take this with a grain of salt, because I too am a newbie. I have an XG1100. When I got it, struggled and struggled to get it converged. The previous owner had used a lot of point convergence. To clear this out, I deleted the input, and recreated it. Write down all the input settings prior to deletion!!!Once that was complete, I set everything to zero and did a static alignment and did a rough convergence in 30 minutes. The end result was 10 times better than anything I had obtained previously. No point convergence required. I do not know if this gets you to "factory" settings, but it does clear out a lot of garbage.
I did not do this without guidance, I was directed either by a post on this site or by Curt. Unfortunately, I do not have the projector or my manuals in front of me, so I can not give you the exact menu commands.
