the first thing to make sure of is that the customer is paying you and being reimbursed by his insurance
you dont want to have to bill the insurance company and possibly wait months to be paid for all those expensive boards
the surge prolly came through the neutral line, no breakers there so everything in the house fries
check ground on the machines other than that you should be ok
the customer will prolly replace the TV before you are back so you can just ask them and make sure the new one never blew up before you install your parts
