Motherboard
A critical short circuit has developed on the motherboard, likely within the power delivery system or a core integrated circuit such as the APU or Southbridge. This prevents the console from completing its boot sequence, resulting in the 55-second blue light blink before shutdown, lack of USB power, and limited fan activity. This aligns with findings in similar cases where multiple components on the board exhibit shorted conditions.

APU (Accelerated Processing Unit)
The APU is a common point of failure for the Blue Light of Death, often due to degraded solder joints or internal component failure. While the motherboard itself shows a general short, the APU's failure can be the root cause, leading to the system's inability to initialize and causing the observed boot loop and shutdown behavior.

Power Supply Unit (PSU)
This can manifest as a Blue Light of Death, preventing a full boot and causing the system to shut down prematurely. It is a common, albeit less likely in this specific case given the short circuit finding, cause of power-related boot failures.
