PS4 coil short – CPU hot

[rfcomputer]

Hi I have 3 PS4 that has the same problem. There’s a short on coil near APU. When I inject voltage on coil APU become hot (with thermal camera). Is APU damaged or are others problems on it?

Coils next to the CPU, likely vcore related have very low resistance. You can’t measure for a short there. If you inject voltage on the coil, then voltage will go directly to CPU and CPU will get Hot. That’s not a short. You can start by testing Dc mosfets, usually found next to the Dc socket. If you get a short on the drain, you can inject voltage there and monitor the board under a thermal camera.
