Just wish I knew why the failures

I'd be very careful with the repair.
Remove the damaged components.
Replace the regulator IC11.
Check for shorts on the 5V output.
Check you get 5V before replacing the ICs.
One component failure is just possible, two is very likely due to overvoltage or reversed polarity.
