Narrative:
We were descending via the STAR and there were scattered thunderstorms along the [route] so we turned on the radar while descending and both mfd's (multi functional flight display) went blank. We reset the mfd's via the company procedure and they didn't reset but [on] the second attempt; the mfd's reset and the radar was up and running. ATC asked us if we were descending via the STAR and we said yes. By the time we got our mfd's back up and running; the fix we were going through was between 21;000 ft. And 17;000 ft. And we were actually going through around 15;300 ft. Which is low for that fix. The rest of the STAR; approach and landing were normal.we were distracted resetting the mfd's and getting the radar up for the thunderstorms in the area. It was RNAV fixes on the STAR and the priority was getting the mfd's back and by the time we got them back up; we were low on the one fix.
