Perhaps the lengthy eulogy for the Canon HF100 was a bit premature. I finally broke down and unscrewed a couple panels, and within about 15 minutes of staring realized the micro-switch that turns on the screen was stuck. I poked it with a screwdriver. It un-stuck itself. Everything is working again.
I'm now back to planning ridiculously mundane videos like "how to cook on a non-pressurized alcohol stove."
As for the poop flood in my boat? I'm almost positive a new hose clamp is going to solve the crisis.
I'm going to anchor out and watch the fireworks tonight.
