Haha..I wish....Room solutions are what I push.

Cable boxes and DVD players in each room? Kind of messy don't you think?

Nope. They go in the closets. Done correctly they aren't messy at all. Control it from your head end and you're done. All this matrixing is cool and necessary at times, if it works....but....I'm in business to make money and to provide a working system that isn't going to take multiple service calls to fix and cause me to lose sleep at night.

So we got on site today and tweaked the extenders and the problem seemed to disappear...BUT...I got thinking about EMI and decided to turn the lights in both of the rooms on and off...guess what? The video signal drops out momentarily once the lights in the room are energized....The bone heads that ran the wire must have run too close to power lines...shoot me now!@$##@$#....lol

Did you guys run the wires, or were they already there?  Can you re-run them?

I don't have a quick fix for that.  Sorry.
That would be a better solution. But the client's two sons disagree. And they know more than me because they work in finance. -Fins 2013.

No this was a job wired by another AV company. We took it over. For 5 DA zones, 1- 5.1 Theatre room and 2 TV locations he only paid 800.00. Couldn't believe it....

It would be difficult to run new wires. The basement could be done with drywall cuts but the 3rd floor probably not.....Brand new reno so I doubt customer would want us ripping out drywall.....They did run cat6 shielded so I'm hoping grounding the drains will fix this...I'm not very hopeful though

I took over a job that supposedly done by an A/V tech, and he ran the cat5 on the main truck of electrical feeding the pad. I ended up running an HDMI cable, conduit, and some extra Cat5e's... This was only with a Snap HDMI extender, it was a nightmare.

Gman.
Glade to see it was an EQ tweak that cleared up the issue with the LG DVD player. To clear up the issue with the light switch effecting the extenders, you need to terminate the shielded Cat6 drain wires at each end to the shield of the CAT6 plug. The will reduce the EMI interference that you are seeing.
Again if you have any question at all please give us a call at SnapAV

The difference is actually palpable. All of the manufacturers chose a standard and designed their data transmissions to be maximized by using that standard. The number of twists per unit length is the issue. The green and orange pairs have different number of twists. We all know how HDMI is finicky at best with the cable. Implement it over twisted pairs and use a different standard than recommended, boom issues most of the time. Micro-reflections can easily cause the issues you bring up due to non standard wiring terminations. Not saying that it is causing the real problem. I always pull shielded cat-6 for any HDMI matrix solution as I had nothing but problems with non-shielded. For the last year (fingers crossed while knocking on wood) I have had none on 4 Snap 4x4 matrix installs. Best of luck with finding the solution.

+1

I would agree that it would matter. We do everything in B now and never use A standard unless it asks us to. I have switched from A to B on a Balun before and it started working instantly. I believe it has everything to do with the how the different pairs are twisted.

Could a switch suppressor help? (arc suppressor?) They are normally used to stop popping sounds through speakers when lights are turned on by absorbing the initial arc as the switch is flicked.
I guarantee I'll tell you the truth and I guarantee I'll tell you what you need to know but I can't guarantee that I'll be telling you anything you want to hear.

Not sure if it would work. I have no experience with them. I'm going to wait until the Snap Cat6 ends for shielded cable come out to see if they will fix the problem.

FYI, you don't have to wait for Snap to release Cat6 shielded connectors. ICC has Cat6 shielded connectors and are available through ADI.

I don't belive this problem is do to the proximity of the extender wires and the power lines. You can test by just running a wire on the floor from the rack to the extener. This will at least let you know where to spend your energy on the next fix.

With the behaviour I described; what do you think it might be?

Have you considered using the HDMI outputs rather than the cat5 outputs and placing Solocat HDbaseT extenders between the matrix and display?
