I guess those HDMI ports are not build to take much of a surge.

I "fixed" the problem for good by switching to component video, which looks just as good to me and cost under $200:

HDFURY Gamer 2 Component - $159.00
HDMI® | 3 RCA Component | Toslink Wall Plate - Coupler Type - $10.04
35ft 18AWG CL2 Premium 3-RCA Component Video Coaxial Cable (RG-6/U) - $21.27


I subsequently discovered that the USB section of my laser printer also bit the dust during that storm. I "fixed" that problem with a $7 USB to Centronix cable.

I just recently had to repair and replace my denon HDMI board even though my system is protected by a surge protector. The only other two sources that could have caused my damage are 1) my antenna 2) coax cable. I have since disconnected my antenna since I hardly ever listen to radio anyway. HOwever, I am looking for ways to protect my devices from surges that may come through the coax line

Would something like this work?

http://www.parts-express.com/cable-...source=google&utm_medium=cpc&utm_campaign=pla


IT sounds like if there is a direct strike there is little hope of protection. but maybe something linke that surge protectors for the coax line would protect against other random spikes

Let me know your thoughts

No to the lightning rods

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.

I live in Florida and have had this happen to 4 TV's and all the networking equipment every time . The house has a whole home surge protector , but that doesn't help. Lightning creates what is known as EMP (electro magnetic pulse ) , similar to what would happen with an atomic air explosion. Any sensitive electronics can get cooked and it seems that the HDMI ports are especially susceptible . AS to the lightning rods , they would only make it worse
a) attracting more lightning and b) creating a giant Faraday cage
These links will help 'splain it

to protect against a surge through the line during a lighting storm is it ok to just turn the surge protector switch off or do I have to unplug it?

Thanks

Unplugging is really the only option...if lighten can travel several miles through air, it has no problem jumping the air gap between a small UPS switch. UPS/surge protectors are meant to handle surges on the power line from transient strikes the line further away or irregular power down, not so much direct strikes very close to you house on at your house...that includes whole house UPS' too. There's a reason why all the surge/UPS protectors generally have a statement in their warranty's such as Leviton's whole house surge protector product:

“Power Surge” means an electrical transient or spike on the AC power or communication lines, including those caused by indirect lighting , against which surge suppressors of this type are generally designed to protect as recognized by industry standards.

That being said, a lot of home insurance will cover damage from direct lighten strike which a lot people seem to forget about when losing a lot electrical equipment from a direct strike.

Thats a good point!

After losing my HDMI board two times in my Denon, I am thinking about going to a UPS instead of just a surge protector.

I will have on it my cable box, lcd tv, dvd player and my denon receiver. HOwever in researching UPS, I am reading about Pure Sine UPS versus simulated sine UPS and I am confused.

Do I need Pure Sine UPS for my intended use?

Sincerely

I live in an apartment. Recent storm here fried 2 satellite receivers, modem and all HDMI ports on LG 3 year old tv. Have replaced modem, receivers ( no cost), however am not happy using components on tv. Satellite rep says board for HDMI ports can easily be replaced for appoximately $100, that I should find one online. I am having no luck in finding the model number for same. Has anyone tried this? Is the board for the HDMI ports called the video board or is it the main board? I have read so much and am thoroughly confused. I did have all connected through Monster surge protector. Any info is appreciated. thanks

Have now determined I need a main board for the LG tv, and the model #, however each site is out of stock. Is it within the rules here to ask WHERE I may find EAX63333405(0)?
Thanks

I have my Home Theater on two APC Backups/surge suppressors. Lightning hit right outside my house and fried my Yamaha 765, but did not hurt the Samsung 63" tv, the Samsung Blu-Ray player, the dvd player, Dish Hopper with sling, or the speakers and sub. All were hooked to the APCs. Luck of the draw. I purchased an Onkyo 636, since that was my second Yamaha and I was ready for a change. I looked into getting APC to replace the Yamaha, but if you ever read their warranty, it would be a waste of time.

Several issues - first, you should post in a forum specific to your specific TV or in the display area.

Second, there are no new boards and all legitimate supplies are rebuilt and must come from a factory parts distributor who will have to order it. eBay and the like may be used or salvaged from broken TVs.

Third, there are 6 major variations of a LV5500 with 4 to 8 sub models in each, so getting the right board will be a challenge. And it is a non-returnable, non-refundable item, so if you get the wrong one - too bad. The high number of main boards in use is part of the reason that no one would stock them. They are probably not even available for stocking, only when requested.

Fourth, the cost of the one you listed will be in the $225 - $325 range, depending on the markup needed by the company you order it from. The official MSRP is unrealistic and only warranty replacement would ever use it.

Thanks, I realize it would be a refurbished board. Sorry posted in incorrect form, newbie here.

I had this happen to me recently and lost most of my HT gear and some computer gear etc. My question is would this gear with bad HDMI be worth anything to someone? I see some of you have had your equipment fixed, so not sure if the cost associated with it would make it worth anything. I just hate to throw a $4000 JVC projector and $1500 receiver in the trash if someone could salvage them.
Thanks in advance

The hdmi ports usually end up going out, and it does not take a lighting storm to do it. Unfortunately brand to brand runs into the same issue. If you are handy You can take the back off your TV. Follow the traces on all your hdmi inputs, and they will lead to a single hdmi controller chip. Remove and replace the chip!!

Voila, all your hdmi ports will be working again.

It is usually a square chip like the one below.


To remove and replace it requires you have a solder station and materials, and the willingness and patience to change the chip. Usually most TVs will be close to upgrade time when this happens anyway, But giving it a go on the old TV even if you just buy a new one, can be a learning experience, and make a good TV for a spare room or cabin, Or even a nice present for the needy.

Unfortunate they do not make more board chips on removable dim like a lot of OP sockets found today. The whole hdmi thing is really a production fault that should be fixed. People's hi end tvs could easily last 25 years or so. But today your lucky to get 5 or 6 out of your hdmi ports, no lightning required.

I don't think that just ANYONE can replace the HDMI Chips (see typical photo above)....there is an entire De-Soldering SYSTEM that is used to heat up ALL of the Pins at the SAME Time for a Very SHORT period of time so the chip itself it's overheated....and when soldering the new chip on to the PAD you have to have the RIGHT amount of Solder...too much will short out the very closely spaced pins. So, leave it to the EXPERTS at a Repair Shop that has the RIGHT Equipment and EXPERIENCE to get the job done right....and BTW, MOST Repair shops only have the "expertise" to swap out entire Board Assemblies, so SHOP AROUND and check on the COST of a Factory Authorized Repair (which would probably be a Board Swap anyway)....

So my WOW technician came out today and figured out that my ONE TV was no longer working receiving a picture due to my HDMI port(s) from last week's bad weather.

I find that...odd.

You would think that it would have zapped more of my TVs if that was the case wouldn't you? Everyone else here is replacing multiple appliances.

I know, this thread is old but it seems like it is still relevant with some good discussions. Last year we had a lightning strike close to our house which took out the TV, security camera recorder, HTPC, LAN port of printer and a video card of another computer. It seems to me that the HDMI ports were the common denominator, except for the printer, so to make a long story short and bearable I replaced all of the parts and repaired them myself for about the same as my insurance deductible. Everything was hooked together through the tv, except the printer.

Well 2 nights ago we had another close lightning strike and it took out 2 of the HDMI ports on the tv and a HDMI port on the new HTPC. I do not have to replace anything this time because there are other HDMI ports to use - next time it will be time for more repairs. I came looking for answers and I suppose I got them - disconnect the HDMI ports when bad storms are coming.

For the record I do not have traditional cable running into my house - we live in the country and have an antenna that receives internet via wireless signal. We do have cat 5 cables running all over the place for the security cameras all over the place. The first lightning strike was extremely close so I feel that nothing would have prevented the damage that it caused. I'm a retired master electrician with many years at a utility company so I'm familar with what lightning is capable of causing. I just wanted to share my experience.

My 75" tv was very simple to repair. It has 2 boards so I replaced both of them for $325 with a phillips screwdriver. The tv sold for about 2K originally. If your is like mine it will be easy to repair if you can perform minor repairs, do it at your own risk of course.

I built a new HTPC and installed it in a cedar box so it doesn't look like a computer. The old HTPC was in a aquarium filled with mineral oil. The old HTPC still worked using the VGA port, (onboard HDMI port bad) so a new video card fixed it so now it is downstairs in the playroom tv.

Repairing these HDMI ports is .going to get expensive eventually. Thinking of getting a seperate monitor for the security system so at least it will seperate some of the equipment.

You NEED to check your house grounding. Make SURE the electrical panel is grounded properly to a ground rod pounded into the ground, right outside where your service entrance (meter) is. Follow the ground wire outside, and you might have to do a little digging to find the rod. Make SURE it hasn't come disconnected from the rod. I've had that happen on an previous house we owned. If it has, sand or wirebrush the end of the rod, and get it re-connected. Be careful though, as there could be a voltage differential there capable of knocking you on your butt at a minimum.

Once you KNOW that's correct, then check and make sure any internet cables, or coax cables from an outdoor tv antenna or whatever coming into the house from and outside headend/or entrance box is ALSO grounded to that rod, NOT to a separate one somewhere else, and/or NOT grounded at all. If they aren't fix it.

Then, make sure all your electrical outlets are properly grounded, AND don't have reverse polarity. Buy a checker for this at Home Depot, Lowes, or your local hardware store. IF any aren't right, get them fixed.

All of that I mentioned on mine are all perfect, and I've had two lightning strikes within 300' of our house in the last few years that blasted the tops off of trees. I almost jumped to the ceiling out of my living room chair due to the sound, YET, all my FTA satellite dishes, (KU and a BUD) outside OTA tv antenna systems, and everything else survived. NO damage at all.

Yes, even IF it's all correct it's still possible to lose equipment to a ground pulse, BUT, it's much less likely.

Thanks for your reply. You may have missed the part where I mentioned being a retired master electrician, I failed to mention that I wired the house myself. It is grounded properly. The induced voltage from a lightning strike can be huge if there are wires around to get induced to. It seems like the hdmi ports are very sensitive to voltage spikes. I feel like the first strike was induced by the camera cable system but it would be hard to prove.
