The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button.

Issue : The motherboard is not powering on. Only the 5V rail is present. The 3.3V rail is missing because EN1 on the SY8286B remains stuck at 0V. This signal is driven directly by the EC/SIO. I replaced the 3.3V regulator and confirmed it's working.
