Panic Attack

Bad day. Brand new Console wouldn't power up! Kudus for ETC, their tech TW had me take the console apart and we fixed it! Phew. But it is slightly different to running just the Software. Also theatre called to say right stereo channel out - so I am losing time here. I need to know quickly;

How do a "swap" what's on the monitors? Tried swapping the output leads but the dang thing still put the browser on the right screen! I want it on the left. And

What/How is that big [MASTER] button over the cue faders? And

Where is the master fader and blackout?

I'll be reading late tonight if someone doesn't see this soon.
