R720 front LCD display is not working. Can't find DRAC IP.

We have a remote location where a user made me aware of a server that had a fan running at "Mach5".  So I had the user look at the front display to find the DRAC IP address because my predecessor didn't think it was a good idea to keep documentation. The LCD isn't showing any information.  We rebooted the server last night remotely.  It would not boot back up as it was prompting to "press the f1 key to continue" this morning, but rather than giving me the reason why it was prompting, he just pressed the key to get the server booted up.  The front LCD display still isn't working.  The fan is still running at "Mach5", which I assume is 100% and I still don't know how to access the iDrac.

Please assist.
