Thank you for sharing your experience as it may be helpful to others to think about surge protection living here in the Lightning Capital of the US. These events are usually caused by an indirect lightning strike to a nearby tree, flag pole, wall, house, or even the ground. This is in contrast to the more powerful but far less frequent direct lightning strikes that was experienced in the Village of Pinealls last month and Calumet Grove last year.
You reference that you had SECO surge protection on your electric meter that is intended to protect hardwired (that which you do not plug into a 120 volt wall outlet) equipment such as the A/C. This is frequently misinterpreted to mean "whole house" surge protection. SECO also provides a starter kit of secondary surge protection devices or point of use plug in protectors for any piece of electronic equipment that has a microprocessor and is of value. TVs should have surge protection that includes the coaxial cable that comes out of the wall should pass through the surge protector before going into the TV. The same concept usually applies to computers with a telephone connection. And do not let a Comcast contractor tell you that this isn't necessary because there is surge protection on their box outside of your house.
