Antminer S7LN - One Board No Longer Working

Antminer S7LN has been running fine. It started beeping today, which it occasionally does when it loses internet, so I reset it with the power switch. When it came back on, only one board is hashing. The other ASIC board reads 30 chips instead of 45, and 0 temperature and shows 30, -'s for the status (the other board reads 45 chips, 71 temperature and shows 45 o's for the status). Is there anything I can do to attempt a repair or is it just a lost cause? It's running at around 1.4TH/s, so I assume just one board is working.

Edit: I rebooted it again, now the bad hash board is showing 30 o's for ASIC status. I tried rebooting it a third time, now it shows 30 -'s again for ASIC status but then after a few minutes shows 30 o's again but still not hashing or showing any temp.
