I seem to have found a reliable pattern for getting the LCD to come on. If I boot the system with the HDMI connected, wait until the desktop is displayed, unplug the HDMI, press the power button and wait for the LCD backlight to go out, reinsert the HDMI and press the power button again, the LCD comes up and is fully functional.
This is baffling.
