Not sure if anyone has heard of this before, very strange. After a lightning strike it appears that besides being left without Cable/internet for a couple days now, that also the HDMI ports seems to have been blown on 3 comcast receivers, 2 Onkyo AV receivers, 1 TV, 1 projector, a HTPC, and a PS3. This is the most bizarre thing I've ever seen - it's between three different rooms, all with surge projectors.


Since I have no incoming cable signal to my house, I think maybe the surge can through the coax cables (which I did not have through surge protectors) and then through my cable boxes' hdmi port to my other devices.


Have any of you heard of that before - a surge taking out only HDMI ports?

This is my understanding of your situation from my experience in this field. Damage to connections between non co-located devices due to lightning is more likely than to connections between devices which are co-located. Having a coax cable in the mix creates an additional risk because it adds another path for lightning to enter the environment. Voltage rise on ground lines of thousands of volts will occur during lightning strikes for a duration of a few hundred microseconds which is sufficient to damage any electronic device. Surge protectors only protect the AC line protecting the device power supplies and apparently worked since none of the devices were reported having been killed. Damage to HDMI inputs is often reported in various AVS forums. They therefore seem to be more easily damaged then other inputs. The manufacturers obviously don't think having a more robust HDMI input, which they could do IMO at a small cost, is needed.

Certainly a possibility.

Easier said than done I think. Even the small increase in capacitance from a shunt mode device can affect the signal on the TMDS lines at the frequencies they operate. If they could do it at small cost, I think they would. It would pay off in reduced warranty claims from damage due to surges and electrostatic discharge.

Well here is what was in the three rooms that got cooked:


Epson Powerlite Home Cinema 8350

Onkyo TX-NR609

Onkyo TX-SR607

Sony PS3

Hannspree HSG1102

Sharp AQUOS LC-52D65U

HTPC (Motherboard with built-in HDMI: GIGABYTE GA-Z68MA-D2H-B3)

2 x Motorola Comcast HDTV receivers

Motorola Comcast HDTV DVR receiver


Out of all those the only device which still has all it's working HDMI ports is the Sharp AQUOS - all the other devices lost any HDMI ports it had. So I guess I know which brand I'll be purchasing for now on...

Wow, I'm sorry to hear this. I didn't know HDMI port was this vulnerable to lightning surges.


You so need lightning rods all over your roof.


Lightning once destroyed my mowing robot's PCB, its charging base PCB, the ADT water sensor, the main ADT keypad panel all in one shot. But laying down such lengthy low-voltage peripheral wires for my mowing robot is an invitation to lightning in the 1st place. Now I know better... Sorry I digress.

Lightening rods won't help if he doesn't have a roof antenna and the surge came thru his cable connection. The cable company should have adequately grounded the cable box at the house or, if you live in an area that is prone to strikes, a whole house ground might have helped.

I'm a bit confused. .. . no incoming cable but has coax cables??




At any rate, Otto and others are correct. Surge protectors will not have helped on incoming other connections like phone, power, or cable service and boxes. In fact, lightening does not even have to have a direct hit to cause damage. For instance, power lines, cable and phone lines, and even an outdoor antenna can pick up a huge EMI spike if lightening strikes nearby (even within a few hundred feet) to those wires or objects. A fairly high voltage can be induced in conductors near a strike and passed on to connected equipment. I had that happen to a phone and answering system, a TV distribution amplifier connected to an attic garage TV antenna, and the connected equipment.

I think I just had this happen to me! Last night we had a lighting strike take out all power in the house. They finally got to us 24 hours later and found that the breaker out at the transformer had blown, and in fact, they had to replace the entire transformer.


We're back up and running now. We have a house full of electronics in most rooms. Nothing in the house is damaged except for anything using an HDMI connection?



I don't know much about electricity, but this just doesn't sound logical. Unless, the HDMI ports are the most sensative thing in the house? Even then, the fellow from the power company assured me that if it blew back at his transformer that there would have been no spikes at our house.


I don't have cable. The entire system was plugged into a J10 surge/battery protector. It was running when the hit happened, but I was able to safely shut everything down due to the battery taking over.


Frustrated!
Any comments?

Could well be. My only suggestion is to try resetting back to factory defaults for all of the HDMI devices.

Thanks Ken. I'm bringing my PS3 to a friends this morning to see if it works through his system. Then will pick up one of his pieces and see if it works in mine. We'll see what that tells us. I'll also reset. Although, I'm not sure how if I can't see anything over the projector.

I feel for you - I've just finally recovered from all of mine. Lucky most of my stuff was still under warranty, so I did most of the repairs through that in order to avoid insurance. Was a pain dealing with all of them though. For the PS3 I ended up sending that to Sony - they charge $100 to fix it if out of warranty.


For me I believe the surge came through the coax, which is the one think coming in which I didn't have protected. Some of those surge protectors have warranty coverage on them if anything gets damaged from a surge - you could try doing a claim through that.

Sorry, I meant that my cable signal was out as a result of the lightning.

And I stated I didn't have cable, but I do have coax coming in from my OTA antenna. That wasn't running through my APC. I suppose it could come through the ethernet line too?


I've seen alot of posts regarding the topic, but very little in the way of associated costs. My list so far seems to be.


Integra 40.1 processor = $1000

PS3= $250

Bluray player = $150

HDDVD player = $150

Projector = $2500


If I have to ship each item in for repair at an average rate of $150 x 5 = $750

Sorry to hear that, for the record nothing protects against lightning. A ground block is there for potential differences and to bond to the electric for that reason nothing more.

Is the OTA antenna on the roof, or is it plugged into the outlet (amplified)? Maybe came in through your outside internet source, then over the ethernet? Either way, not much you can do to protect against a direct lightning strike.


Well hopefully some of your stuff is still under warranty. There's also insurance - although I'm sure you have a deductible. You can also tried filing a claim with the maker of your surge protector - I know the ones I have give up to $100,000 warranty. Not sure how successful anyone has been filing a claim with them. I believe they require you to ship them the surge protector, so they can inspect it internally for signs of surges. Most likely get denied if the surge occurred outside of it (through coax, ethernet, etc).


I wish you the best of luck, this was not fun dealing with. At least for the PS3 repair it was pretty painless. Paid $100, they sent me shipping box with postage/label included, and I got it back within a couple weeks. You may lose everything on it though as they may replace it with a refurb if they can't repair it.


This ended up being my final damage:


Epson Powerlite Home Cinema 8350 (Warranty replacement - within a few days)

Onkyo TX-NR609 (Warranty repair - almost 2 months)

Onkyo TX-SR607 (Warranty repair - almost 2 months)

Sony PS3 ($100 to repair - 2 weeks)

Hannspree HSG1102 (Warranty repair - 1 month)

OLEVIA 32" HDTV 232V (Bought Sceptre 32" LED HDTV - $220)

HTPC Motherboard GIGABYTE GA-Z68MA-D2H-B3 - (Store exchange - within 2 weeks of purchase)

Sony Subwoofer SA-WX700 (Purchased Polk Audio PSW505 - $230)


So ended up spending about $550 total, and alot of headache with warranty claims. Epson is definitely the best - had a new projector to me in a couple days, and then just stuck the broken one in the included box, shipping included. Onkyo repair sucks, taking nearly 2 months - will not buy from them again.

That's quite true.


Grounding and other protection measures are only good enough for the induced field of a nearby strike. Nothing will hold back a direct hit to an antenna or the house electrical system. Here grounding helps prevent a fire but will not protect any electronic equipment. The rise time of the voltage spike is just too fast for anything to protect sensitive electronic components.

I just brought my PS3 to a fringes and it worked fine through his tv. I may have narrowed it down to my projector inputs, and possibly my processor. Still working the problem.


Yeah, the deductible would be too high to make a claim....and nothing is under warranty.

This just happened to me the other day. I have a Onkyo TX-SR705 and all 3 HDMI ports are blown. Im glad i found this forum, I was racking my brain trying to figure out why none of my stuff would work through the receiver.
