Could comcast have caused this???

A couple of weeks ago, my mom lost her cable, phone and internet.  Days later when the Comcast tech came to check out the issue, she needed a new modem.  The HDMI1 input on her TV was blown and she needed a new HD cable box for her family room (good thing she had more then one HDMI input), both bedroom cable boxes (one HD box and 1 converter) were dead and needed to be changed.  Now her computer will not start up and her phone/answering system was dead and needed replacing.  Everything that started from the comcast modem was DEAD.  The tech said there must have been an energy surge BUT she never lost electricity, had blinking clocks, etc.  Could this have originated from Comcast?  Is it possible to have a surge through the cable/phone line?  Thanks for any help from someone that might know!

the tech said the outside levels were 28 and should have been between -7 and 7.  he had to change something outside as well.  electricity in the house is fully grounded.

A nearby lightning strike can cause all of that damage.

Lightning hitting a utility pole can send a huge surge in through the cable.

 

Has she contacted her homeowners insurance agent?

but the clocks were not effected so there was no electrical surge through the house.  only the items that stemmed from the modem were blown.

It can happen. Last July during a thunderstorm lighning struck a pine tree in my front yard. The tree sits smack dab in the middle of power, cable, and phone lines.

 

The result of that strike was 2 of my cable boxes, 2 of my 4 tv's and my computer motherboard got zapped. The other computer in the house was not affected. An expensive component of my central ac unit also got hit and the component had to be replaced.

 

We are not sure exactly what happened. If it traveled through the electrical line it stopped at the ac unit. Or it could have struck the unit directly but we saw no evidence of that.

 

Most likely the lightning went through the cable line and only the above mentioned items were affected.

 

We are grounded. Had some electrical work done in 2008 and it had to be grounded so it could pass inspection.

The surge didn't come in on the electrical lines.  It came in via the cable line.
