Can a power surge damage an HDMI cable? Absolutely. Most any piece of electronics and apparatuses can end up getting damaged due to power surges, and HDMI cables are no exception. Power surges can happen for several reasons, from accidents due to electrical outages to lightning strikes.

How do I protect my HDMI from power surge?

How to properly reset a TV after a power surge?

The first step to properly resetting your television after a power surge is to unplug your TV from your wall outlet so that no electrical power is being provided to it. Then, unscrew the HDMI and any other audio/video cables which are attached to the television.

Can a power surge cause a HDMI connection to fail?

Surge protection is about hundreds of thousands of joules dissipating harmlessly outside – in earth. That means no surge current is anywhere inside a building. That may have created the original problem. But that is not blowing out HDMI ports. So, stick to one problem. HDMI ports are not as robust as other connections.

How much voltage does a surge protector need?

The surge protectors do not protect from this as the clamping voltage is 330 V. I haven’t had a repeat event like this since then and because it was a whole house occurrence (everything was buzzing and light bulbs were pulsing), it seems likely that I was getting excessive voltage from the utility.

Can a lightning strike cause a power surge?

While unplugging all your electrical appliances during a thunderstorm may sound a bit unnecessary, doing so can protect your devices from damaging power surges. If lightning strikes the electricity cables that run into your home, the bolt can surge through your electricity supply and overwhelm the electronics attached to it.
