Good Morning,
I'm trying to identify the cause of some failed electronics after a thunderstorm Tuesday night. I happened to be in the living room when there was a lightning flash and thunder that shook the house. The power flickered and I heard a pop noise, it sounded like a half second of loud white noise. I assumed a surround sound speaker or something made the noise even though everything was powered off. Wednesday morning I find that the TV will no longer turn on, have tried a few outlets throughout the house. The comcast modem and cable/DVR box were also dead. I was able to get the modem to power up but the DVR box will not. I still don't have wifi, technician is coming tomorrow.
So, everything is plugged into the same surge protector except for the TV. Everything on that surge protector seems to be unaffected, accept the comcast equipment. The TV is plugged into its own surge protected recessed outlet (datacomm 45-0041-wh). The surge protector has not given me an audible alarm as it should when it has failed and it doesn't appear to be damaged. I have attached a rough schematic of how everything is wired. Can a power surge come through the coax and kill the comcast equipment? If so, I can't figure out what happened to the TV.
I should mention that several months ago, the Foscam camera unit in the schematic, lost it's ability to connect to the internet. It has an ethernet cord directly to the modem. The unit still works, just won't connect to the internet. I had an electrical engineer at work look it over and apparently the ethernet port is fried. So I potentially have had a ghost inside the electronics for a while.
Thank you for any help you can provide! I will be buying a new TV but I'm not comfortable plugging it in until I know what may have happened...
