Thanks for the info. It’s been many days since the surge occurred.I think the 3B+ has a PTC/PPTC (resetable fuse) which when triggered hard can a long time to recover.
Leave the 3B+ totally unpowered for 24 hours and try again.
Re-powering the 3B+ before the PTC is fully recovered just re-trips them and would account for the red LED going out.
On the other hand if the PMIC is damaged it could cause the PTC to trip anyway.
