Do Note 3 motherboards work in all models? Or are there different models?

[sbaird50]

My note 3 has had a new lcd and screen fitted, the phone turns on but has a blank screen, I can hear the phone speak, all lights are working, because I got a blank screen I can't see what model it is to order a motherboard. Is there anything I need to do to turn the screen on or is it a new motherboard.

At that point is it really worth repairing? That device is very old at this point, for not much more than the cost of the parts you almost certainly could have bought a new mid-range device or found a more recent Note device.

But, the boards likely will interchange within the same model line...
