If anyone has encountered something similar or has any ideas, we'd be very grateful!

Can you pin down what changed to make it stop working?
Also, here are some specific things to try:
A) If you think the problem happened after updating the firmware, it's remotely possible something went wrong during that process - in which case you might try re-downloading and installing the latest build, and re-updating the firmware.
B) Also, when the board is first powered on, all 4 leds turn on for a second, then all but the red power led are on as the board begins initialization; then after it initializes, the green S1 and S2 leds should come on. Do both of these LEDs come on and _stay on_?
C) The other test is, as Caboose mentioned: can you use the
navXUI on a PC to display the sensor data?
So after you perform A), let us know if C) is successful and if B) shows both S1 and S2 leds on.
P.S. Can you please also indicate the version of RoboRIO firmware you have installed?
