1. Powerboard replacement
If no success, then (and/or)
2. Mainboard replacement
If no success, then (and/or)
3 T-con board replacement.

No idea what could have been damaged during storm, can be any of existing electric parts...Bring TV to local service, they can identifi problem and probably have spare parts to swap.
