There's a couple of holes on the board to put an electrolytic capacitor.
Beside one of the holes is a white dot. Is that where the positive of the
capacitor goes?

No standard on that, compare with other caps/dots on the same pcb

And if there are no other electros on the board with which to compare it, check the voltage across it, or get a non-polarized cap instead.
