lightning damage/ surge protection
I was out of town last weekend; lightning struck a tree about 100 yards from my house while I was gone. When I returned on Sunday the comcast box was toast (no service), my AV receiver connected to the box via HDMI was non-functional (in protection mode) and won't turn on, and the TV was toast (connected to AV receiver via HDMI). No damage to my cable modem. All were plugged into a surge protected outlet strip (which is still functional) and I have a whole house surge protector (which is still functional). I replaced the comcast box at the local Xfinity store. Did the surge come over the comcast coax? Is there anything I can do to protect from this happening in the future? Is comcast responsible for failing to protect the coax input?

Did you ever get resolution to this? I too had the same thing happen. First time 4 months ago I lost my projector, receiver, cable box, Nintendo switch dock. Second time this week fried my HDMI output again on my AV receiver (this was replaced so it is a new unit) and cable box. Tried to call customer service but they are useless and can't get me to an actual tech. The coax line through the hdmi cable is my suspicion too but not sure how to go about figuring that out. I checked the box outside and the line is grounded there. Hubby is pretty handy so if they can just tell me what to look for/check before sending out a tech that would be helpful so I don't have to pay or waste a techs time.

We just had the same thing happen to us for the second time now! We had our set top box and gateway modem get fried along with a receiver, Playstation, computer docking station, and a security system NVR. I'm positive the surge didn't come through the electrical because we use surge protectors and power conditioners, and because we have other electronics plugged into the same surge protectors as the equipment that was damaged, and only those connected directly to the comcast/xfinity equipment were damaged. I suspect our system was not properly grounded during install. Not thrilled about losing several thousand dollars worth of electronics, especially since we invested in higher quality and more expensive surge protectors to prevent this from happening.
