Talk to the maintenance guy. It is their piano.
That is the best option, of course... assuming that, in a university setting, there is a maintenance guy who can be interested in the problem...
I didn't want to sound cheeky but I don't try to repair something I don't own. As a fellow organist, I've had to play on some very strange instruments. It was the ones with little written notes for the tuner that had the most surprises. Even though I could probably go up into the chamber and fix some things, I never did. "A dog should have only one master."
Very good point... Did you ever have to go up into the chamber and put a hymnbook or two on top of a ciphering pipe's opening? All in the day's work... The worst organs I hit were straight pneumatic action contraptions. When they worked, they were painfully slow. Fortunately there weren't many of them, and most of them are long gone now!
At the risk of pointing out the obvious...Step 1 -- check the mains socket. Does it have power?Step 2 -- find the fuses on the instrument (not sure where they are on that instrument; they may be a little hard to find). Check -- or better yet, replace them with new ones. If you have access to a multimeter, is there mains power at the fuses? If not, why not? Check the power cord; they have been known to break.Now... if there is a regular power switch on the instrument, check to see if it actually works (turns on and turns off)(with the instrument unplugged!). If it does, plug it back in and see if you get power downstream from the switch. If there is power downstream from the switch, or if the power switch is a touch pad or something evil of that sort, and you still won't turn on, you're pretty well out of luck unless you have the ability to start tracing in the internal circuitry. Which I wouldn't bother doing...
