1) Customer buys new RV (motorhome) from a dealer 8 hours away.
2) There are 5 Seiki TVs installed
3) There is one Sony blu ray player
4) There is one Satellite receiver..probably Dish Network...don't remember.
5) There is one Monoprice MHSP0204B 8 way HDMI splitter with 2 inputs.
6) THE MAIN TV HAS A DEFECTIVE HDMI CABLE. (Cable was pre-wired in the RV. It is buried.) Diagnosed by Yours Truly.
7) Customer calls RV dealer for a solution. Dealer advises customer to go with wireless HDMI to bypass defective cable.
8) Customer orders Nyrius NPCS549 wireless HDMI kit. (RV Dealer assures customer they use these all the time in situations such as this.)
9) After installation, the wireless HDMI kit has perfect video on the problem TV. Audio drops out several times, then completely after about 30 seconds. Problem occurs on both sources.
9a) Wireless HDMI works perfectly when the splitter is bypassed on either source.
9b) Running a 25' temporary HDMI cable from splitter to TV works perfectly.
10) I installed the Ethereal DAD JR between bluray player and splitter, then splitter and HDMI transmitter, then between HDMI receiver and TV. No luck on any configuration.

*CONCLUSION* I think I have exhausted all reasonable efforts. I advised customer at the beginning to get the HDMI cable replaced. Unless someone here has a better idea, I believe that is what needs to happen next. However, I prefer to have a solid and profitable solution. What did I miss??? HELP!

I just went through this.
Replaced splitter with another brand and it fixed the problem.

I love how the RV likely cost $250k but they use the crappiest AV equipment money can buy.

I agree with William David Design's solution. I had a similar experience the only time I tried a Monoprice splitter.

That is encouraging! Do you remember the brand you used? I want to avoid the trial and error routine.

You are correct! I can't believe they use this garbage in these expensive RVs.

Take the customer & yourself (if you have time) to the RV dealer and say "Show me!"
They just stated they use them all the time and it works. Make them show you.
If they do show you one working (with the same setup), remind the customer that RVs move around. And many things can and will interfere with the wireless working everywhere he goes.

While youre there, then the RV company to stay out of the AV business and hire and damn pro!

Great idea, but RV dealer is 8 hours away.

Ah forgot about that. Not worth an 8 hour trip to screw with them.

Send the customer! With the reminder about the wireless, even if they do happen to get it to working. And if it does fail, he can insist running a new cable then.
Most likely out come however is the stupid cheap extender will work there. And of course fail when he tries using it elsewhere. But they will refuse to do anything, because they can get it to work at their place.

Following up on what Brad says, you can state (or at least claim) that you can put in equipment that measures up to the quality of the rest of the rolling money pile, and that will perform correctly. But you won't mess any more with that lowest price item that those cheapskates hoped would work, since it's an insult to the client to supply it in the first place and a waste of money to try to make it work any better.

I'm sure they'll understand the concept that the proper equipment will function properly but improper equipment will always find new ways to fail. As I wrote that I was reminded of the Anna Karenina principle, "Happy families are all alike; every unhappy family is unhappy in its own way." And so it is with equipment.

The short answer is no.

It was on my own system and I had maxed out the HDMIs on my reciever so I thought this a good oppertunity to try out a cheapy and see if it worked, which it didn't. I didn't want to invest in a good HDMI since the money would be much better spent upgrading the receiver. I wound up switching the rarey used sources through the TV.

Sorry I couldn't be more help. Just wanted to plus one the replant of that crap Monoprice piece.

Now I should qualify this next statement with a disclaimer, in that I have NEVER worked in an RV, but I agree 100 percent with your initial sollution. Fixing cable issues with band-AIDS like wireless, or what ever, doesn't always work out. We make the money on the margin but lose out having to mess around getting what ever solution to work right, and the customer spends the whole time frustrated. Ideally we know the solution, impliment it, and take the cheque to the bank but if that were the case all the time none of us would post here.

I say tunnel into that thing and run a new HDMI, and a cat6 while you're in there. Labour is always 100 percent proffit and you will be fixing the actual problem. Maybe it takes a long time but so is what you're doing now. I think the customer will appreciate it more in the long run, and you can sleep knowing it was done right and won't be getting a phone call.

This is true in an additional way: labor to fix it right the first time is profit because you won't have to come back out and do the job again, for which you surely would not charge if you messed up this time.

You guys are missing something and the reason why I keep putting it off on the RV dealer to fix this. Running an HDMI cable thru the entire length of an RV, is a nightmare!!! You have to disassemble so much stuff (including pulling appliances and/or furniture, panels, etc...).
All of which will also mean; if he ever has a problem in the future, the cheap dealer will most certainly say you damaged in taking it apart & putting it back together.

I would say 'you' fixing it should be a last resort. If at all possible, have the customer make the dealer fix it the right way.
If they won't, then quote time & materials for fixing it and inform the customer the possibility of the dealer giving him crap in the future on any warranty issues, related to what you take apart and put back together.

I found a possible solution. Iogear GWHDMS52MBK4. [Link: iogear.com]

With this, I can transmit to 4 receivers about 12 inches away and use 1 existing HDMI output on the transmitter. I am very concerned about a remote that had edid buttons on it for a non-technical customer. Anyone had any experience with this or similar models?

The client would be better off paying you to drive the RV back to the dealer for him, putting you up in a hotel, and having you bring it home once it was fixed. At least it would be done right and maintain the existing warranty, assuming there is one. Based on your initial post it sounds as if the thing was brand new.
