Symptoms

  • Powers off shortly after powering on
  • Automatic Shutdown after pressing the power button.

Solution

  • Shutdown within 3 seconds: Short on 12v power rails.
  • Shutdown within 10 seconds: Short on APU power rails.

If shorts are found on the rails' capacitors, it is probably a chip surrounding them instead of the capacitors themselves. Try to remove surrounding chip one by one and test if the shorts are still there until you find the faulty chip.

If you just replaced the HDMI port, double check your work and make sure you don't have any pins bridged.
