APU BGA Reballing Service
The pulsing blue light indicates a failure to complete the system check, most often caused by fractured solder balls under the CXD90044GB APU. A professional reballing service replaces the degraded lead-free solder with leaded solder, restoring electrical continuity between the processor and the motherboard.

Internal Power Supply Unit
If the PSU's 12V rail is unstable or cannot provide sufficient amperage when the APU ramps up during boot, the console will hang in a pulsing blue light state. Replacing the PSU ensures that the power delivery network (PDN) is meeting the transient demands of the Pro model's higher wattage requirements.

2.5-Inch SATA Internal Hard Drive
A corrupted or physically damaged hard drive can prevent the PS4 from loading the system software during the initial boot phase. If the console can boot into Safe Mode with the drive removed, the HDD is the confirmed point of failure, necessitating a replacement and system software reinstallation.
