Can you elaborate on this by showing us the path taken by the strike
through the TV?

Path to earth was through the network and into a third computer.
Through that third computer's motherboard, through modem, and to earth
via phone lines. Semiconductors in these paths were damaged.

We literally traced this path by replacing ICs. Some ICs (ie
network interface chips) even had cracks on packages where surge
current entered or exiting those ICs. Absolutely no doubt as to how
surge currents found earth ground, destructively, via adjacent
computers.

I wonder why, since electrical codes in North America
and Britain require a ground connection at each outlet;
computer power cords are 3 wire?
