Welcome to Terry's Forums confusion,
Surge protectors do work, for surges but not lightning.
Hopefully your power provider will absorb the cost of your losses. But could be hard to prove.
Most appliances have MOV protection built in, and may just blow the fuse in the device, you can replace it and it works again.
Not sure about what you say when you say "the three hdmi cords" what they have to do with it, other than maybe power went thru them connections, and burnt things up ?
The power surge protectors are rated with Clamp Voltage, and I use as low a voltage as possible for most household devices.
Sounds like the power company may be at fault, they should not have sent that much Voltage down your line.
Good Luck on your project.
I would go to the power company first, Your Insurance Company will just go after them, then may raise your rates.
