The model I have has 3 buttons on the back, labeled "menu", "+" and "-".

So I may be able to power both the Pi and the screen directly applying 5V current? That could prove useful indeed.

For now I'm just going to try again and be more careful with polarity. If there is no video input, is there some hint on screen to show it's on, like a "no signal" message?

That may be the case, actually. Would that be a possible cause?
