I’m having connectivity issues such as occasional lockups, or no picture when switching video sources to the projector. Is there a firmware upgrade that addresses this?

There is a firmware upgrade available for projector models DLA-RS49, DLA-RS4910, DLA-RS57, DLA-RS67, and DLA-RS6710 to address HDMI compatibility.  The initial December 2013 projector shipments had a version of firmware that was overly sensitive to various HDMI factors (improper cables, switching between HDMI input 1 and 2, faulty connector contacts, etc.). This projector sensitivity caused the projector to enter into improper states and lockups which could only be “reset” by completely removing AC power.  The upgrade firmware and installation instructions can be downloaded here:
