I live in Florida where there's lightning almost daily in the summer. I have a Samsung HDTV I've had for over 7 years, and an Arris Enhanced DVR from the cable company. Everything is plugged into a surge suppressor and the cable itself is supposedly protected by a suppressor and grounding outside the house. We also have a "zap cap" on our incoming electric provided by the electric company to limit effects from surges and lightning. There are other peripherals (Xbox and Chromecast) attached via HDMI to the Samsung.
All these components have weathered intense storms until last week when lightning struck close to the house (blocks away). We had no surges, or electrical interruptions, but suddenly the DVR would not put out a signal. It was operable otherwise as the cable company could "see" it on their network as communicating and functioning.
I unplugged the Chromecast (on HDMI 3) and plugged that cable into the DVR. No signal. They came out and replaced the DVR with a Samsung.
Two days later, intense lightning storm again. A bolt hits relatively close. No surges, etc. DVR stops putting out a signal, but works otherwise. Again I try removing cable from the TV to the Chromecast and plug it into the DVR. It works this time.
Very next day - a storm. TV was not even on. Bolt hits nearby. An hour later I turn on TV & DVR - no signal from DVR. I try exchanging cables/HDMI ports. Won't work. I plug a monitor and a different HDMI cable to DVR. Again the output is fried.
All the HDMI ports on the TV are operable as are the HDMI cables, as Xbox and Chromecast work fine on them.
Just got another DVR today, but I still have no idea what's doing this or how I can prevent it. Anyone have any thoughts?
