A couple weeks ago, we had a lightening strike very close by. The power did NOT go out, not even a flicker. At the time I thought nothing of it. A few days later, I tried to watch something on my home theatre system, and my Epson projector was not recognizing the HDMI signal (it worked good for 4 years prior!!). The projector is supplied from a Pioneer VSX-23TXH receiver so I tired various inputs (PS3, cable box, computer HDMI output, Apple TV), all with no luck. I then tried plugging directly to the projector with all of the same devices, and also different cables. No luck. I assumed I simply had a problem with the projector. However, I also tried connecting a laptop using a VGA cable, and the projector worked fine, so it was clear to me the problem was specific with the HDMI port. At the same time, I have a Sony television connected as a second HDMI video output from the same Pioneer receiver, and the TV had stopped working. I chalked it up to coincidence. In the case of the Sony, the television would not even turn on (3 flashing red lights under STANDBY - that is it). At that point, I figured I had a 6 year old Sony which was past its expiry date and a faulty HDMI board in my projector. Today, I purchased a new TV. When I reconnected it to my system (ie through the Pioneer receiver), the TV would not see any signal. I plugged in a computer direct to the TV with an HDMI cable, and it did work, so then I started to scratch my head, and start to wonder what the heck was going on. I tried multiple HDMI inputs and both HDMI outputs on the receiver, and nothing worked. I then also tried connecting the PS3, and it also did NOT work. Everything starts OK, and the sound was working good in the case of my cable box, but no video!! Confused at this point, I am wondering to myself is it possible that all the HDMI ports could be affected?? Everything is connected through high quality electrical surge protectors, so I thought I was covered. Discouraged, I turned to Google to see if I could discover anything, because I was not even sure who to call or what to tell them!!! It is great to find this forum (and other similar threads touching on this same subject). At the end of this drama, I lost the following components:
- Sony television
- Sony PS3
- Pioneer receiver
- Epson Projector
All of these components seem to work fine otherwise, except none of the HDMI ports work. Considering I have invested several thousand dollars in this system, and it is all well past warranty, I am very much hoping that my home insurance will cover this!!
The main point of this lengthy reply is to confirm that a nearby lightening strike can, in fact, wipe out HDMI ports. Every HDMI device I had connected to my system (with the exception of my cable box) has had its HDMI ports destroyed (no visual damage, but they will no longer conduct signals).
Next search will be for solutions to prevent this once I have the system replaced!!
