Oog. Sorry to hear about that... did all of them get damaged at once? If
you live in an area frequented by lightning, the best thing to do is unplug
the sets in advance. That's the best surge protection there is, and it's
free.

It should be noted that power surge suppressors are designed to suppress
unsustained power spikes only. They are completely useless at protecting
equipment from direct and indirect lightning hits due to the sheer amount of
energy that a lightning bolt has. Lightning will exceed the joule rating of
even the best surge suppressor. The advice to unplug equipment from electrical
outlets and telephone connections during a lightning storm, as advised by Mr.
McCullar, is the best way to prevent lightning damage.

As for the original poster, there isn't much that can be done to repair
lightning damaged equipment if you don't have the training, experience,
appropriate service documentation, and the repair equipment. As advised
before, it is recommended that the damaged sets be taken to a repair
professional. - Reinhart
