We don't run into any surprises here; the heat sink remains much the same as its predecessor from 2015.

We take a moment to pluck a familiar pair of presumed power posts from the body of the heat sink.

During our Apple TV 4th Generation Teardown, we suspected that power was transmitted to the logic board via the heat sink screw posts. It looks like this is still the case with Apple TV 4K.

With the heatsink and posts out of the way, the only thing left to do is remove the power supply board.
