Scorch marks on my falcon

You also have a take a look at why this happened! What went wrong, there could be a possibility that something else went wrong and caused this issue, if you replace the parts will it just happen again? (ie order more then a few). Can't see from the photo how back the damage. Fingers crossed it's a simple fix.

The absolute root cause is never likely to be known but the why of them burning is well known.... they get a crack/fracture and generally in that case fail short and can burn.
Why do they get cracked, flex in the board, thermal cycles, sheer bad luck, faulty originally, too hot soldering .... bit of a list but with billions in use the odd failure is well inside any MTBF numbers and falling into the crap happens category
