Well this is the third time ive been out this week for the the same exact problem at three different locations, miles away. Lightning struck and burned all of the low voltage equipment in the home. The low voltage component of TV's, the cable boxes, the modems, the garage door openers (low voltage only), the phones, the computers sound cards, and audio and video, sound cards, you name it, but no line voltage is effected. I feel like as a contractor I should have a definate answer as to why this is the case. I feel like if lighting struck the home, this would be a sign of good grounding ( because there is no damage on the 240V system), but is it something more. In the past I have just told my customers lightning struck, this is the damage, and heres the bill.
I feel like you dont have to have a direct hit for this to happen, however. I feel like this is more of a matter of, you just cant save it all, rather than there is something wrong. What are some of your thoughts on this? In all of the cases, I found no indications of damage to anything other than circuit boards and LV. So, what is the most likely point of entry? Is this a sign of good grounding because the line voltage was not affected? Is it a case of taking one for the team? Thanks for your help!!
