I have a customer who has the worst luck with equipment ever heard of. We are on his fifth AVR in 3 years (warranty has covered it but we are sick of messing with it) as well as 10 or so sets of HDMI converters over the same time period, all of which I have made a loss on.
Some of his equipment was smoked when it was new by a lightning storm which blew a hole through his roof and concrete floor and that killed his lighting control, theatre and everything else electrical including the pool pumps and cooling system.
It is time to replace the AVR and get a solid HDMI solution going, I just dont want to go down this road any more.
He has a 3D panasonic TV, Epson non 3D projector and we want to use his existing single cat5 cables to each location for the HDMI signal. Before anybody says anything, there were originally 3 cats going to each location but the storm killed (fried) the 2 which were connected. This last set is the spare and I just need something that works, no questions.
Biggest problem I can see is the 3D and non 3D mix, but both will be used at different times.
Brands available to me are Yamaha and Denon for the AVR and Wyrestorm looks like my best bet for HDMI extenders.
Will these work together and let me keep some hair on my head????

I was at a friends house lat week who was having issues with a "new" leak after a contractor did some work. The contractor said "I don't believe in coincidences".

This made sense, problematic installations are not bad luck. I have a house or two (or three) where there are ongoing problems, after three years I found one, the other house is still ongoing.

The one I fixed was definitely electrical, the others I'm convinced are too, I just don't know how.

My advise is, Surgex on the equipment, cable surge on the incoming line

[Link: amazon.com]

And use the data surge on all available equipment. After this,if the is a direct lightning hit again, find a lightning rod company, get a price, mark it up and cross your fingers.

You'll be fine with Denon or Yamaha, both hold up to electrical spikes the same, but most here would Lear towards Yamaha, for extenders, wyrestorm are probably fine, otherwise look at zektor, snap (fingers crossed), even the pro connect extenders.

you need to try to fix the problem, good luck, I hate these problems.

The house was hit directly by lightning a few days after move in. Many systems were destroyed and due to circumstances it was decided to use what was left as spare to get up and running again.
The main reason the home wasnt rebuilt from the ground up including all new cables for me was our wet season had just started and removing the roof for even a short time was not an option for at least 5 months. Roof removal was necessary to get to the theatre, it is in a corner of the home so there is no room to even get in the ceiling space near the main wire run.
Anyhow, I dont think many of the problems have arisen specifically from the lightning damage, I think HDMI senders have not really been very reliable in any installation until recently if I look at the amount of threads here and elsewhere detailing the misery and woes of almost all who participate here.
The Integra receivers we have been using have all failed with stupid problems, mostly related to build quality issues with HDMI and control circuitry.
I guess to summise I am asking, will Wyrestorm HDMI widgets work with a Yammie receiver over 2 separate HDMI outputs and give reliable and dependable output day and night through either a 3D capable Panasonic plasma or a non 3D Epson projector depending which screen my customer chooses to watch at the time?
I dont want to be a regular visitor in this guy's house any more, I just want to get it fixed the most reliable way there is.

Put Ethereal HDM-SP (inline HDMI 8KV surge unit).

I have regularly been using Binary HDBaseT extenders with Yamaha receivers with no issue. Just keep some 1x2 HDMI splitters on the truck in case you experience the clocking issues that some of mentioned (myself included). The splitter fixes the issue. EDID issues can also pop up, and Brent can point you in the direction of what is needed to correct it. I think you will be fine as long as you use decent equipment. I have not used Wyrestorm so I cannot comment on its reliability.

What Goldenz said....+1 for Yamaha AVR & Binary HDBaseT baluns. That combo works every time for us.

If you seriously want to design a system capable of either preventing a direct strike or surviving a direct strike, you need to hire a qualified consultant. This goes way beyond the range of surge suppression products that you see in the consumer product industry. To make it clear, your equipment will not have any chance of surviving a direct lightning strike with add on products in this industry. Physics wins every time.
In reality, the products you can buy can more or less limit damage from nearby strikes, and that even has a lot more to do with structure wiring than the product itself.
911 call centers, oil refineries, and other critical system installations have lightning prevention and protection systems that become serious projects and are integrated into the building and surrounding property. Take a look at these guys for an example: http://www.lightningprotection.com/

now that is some serious shit!!! incredible science and technology

I just met with a rep from this company, [Link: surgesuppression.com] at a home that lost some equipment from lightning strikes. We discussed potential reasons the home has been hit hard the last 2 years and went over the products they offer. It's probably worth it to bring in a specialist in your case.

For hdmi extenders also look into transformative engineering as they are very reliable.

I can use Binary extenders as well, so a splitter (I can use a less expensive AV receiver then) will fix any clocking issues and 2x HDBaseT extenders it should be solid.
Thanks, that is what I will propose.
Any info whether the 75 series Yamaha amps have RS232 on board? Using RTI ZRP6 for control and it does not do ethernet.

|there were originally 3 cats going to each location but the storm killed (fried) the 2 which were connected. This last set is the spare and I just need something that works, no questions.


Each cable has four twisted pair. Doubtful that all four twisted pair in any cat 5 cable are destroyed. Consider testing and using any twisted pair that remain intact.

First way to accomplish this is with a megohm tester between all wires. That will not be a complete test. The actual and final proof will occur once signals are put on those wires.
