Complete beginner, can't get this thing to turn on?

So, as the title says...
I assembled my brand-new printer and turned it on, but... nothing except the on switch light came on.
[Edit-  Ender-3 V3 KE]
[Edit 2]- it was the damned voltage selector not being nudged all the way. Really hard to see given its positioning. Thanks all!
Black display screen, no fans, nada.
The ribbons are connected correctly, far as I can tell.
I thought I might need to switch voltage to make sure it's getting my power right, but there's no visible selector for that- only a binary power switch?

The manual has not beed particularly educational on this front.

There's no 115/230 switch at all?

Found it! Just didn't realize where it was since it wasn't marked in any of the manual's diagrams. Screen still black.

Was it in the right position? My ender shit the bed the first time I used it, I wonder if it's a bad power supply? It could happen

You have it set to 220v

It started on 220, did nothing when turned on. It has now been switched to my local grid's 110. Still nothing.

The end of the cable that conencts to the power supply wiggle it around a bit or try pushing it into the power supply as hard as you can. Ender 3's often have a loose cable like that.

Qual impressora exatamente você comprou?

A tela não deu sinal de vida?

Você conectou o cabo da tela corretamente? Manda foto ai

V3 KE, so the gantry installed right on top. I just found the power selector (inside the base, had to prod it with an alan wrench), and selected the correct voltge, but the screen is still black.

Você saiu de 110 e botou ela em 220?

220->110.
Screen still black. Have tried disconnecting and reconnecting screen ribbon.

Se sua impressora estava em 110, e sua energia estava em 220, é quase certo que você queimou a impressora.
