XBOX One Light of Death - Bad MOSFET and power regulation circuitry - Diagnosis and Repair

This video covers the repair of an XBOX One games console with an issue where it powers on then off after around 1-2 seconds, otherwise known as the Light of Death.

In this instance it was caused by a blown N-Channel MOSFET, faulty power regulation circuitry (U9D4) and associated surface mount components.

In this video we cover the diagnosis of the faulty components, their replacement and final testing of the console post-repair.
