On startup only. Two diff clients can't get a pic with cable or DirecTV thru an AVR with passive cables. Mess with it enough and picture appears, fine thereafter.

I know I can give more info, but is there a general issue that covers the start up issues? Can a magic box fix it consistently?

I think Brent was going to tell us in which situation to apply his magic electronic gadgets, but don't know if he ever got to it.

Yes, it can.
This start up issue is due to a lack of Hot Plug Reset.
This can be forced with one of our HDM-VCT devices though the use of control system relay.

What Brent said. He and I have been communicating on this very issue over the past month.

DirecTV sucks and is becoming worse. The bad thing is that a perfectly working install can go to hell after an update that they push.

It has the ability to change the voltage in a device on the HDMI board and cause exactly what you are seeing (and worse).

His device will resolve the problem in most situations.

Could this make a combo of a Sony TV and a wireless DirecTV client require 45 seconds to come up? A B I G hint here is that the power light on the DTV client takes about ten seconds to come on.... so, hey, HDMI!

In this particular client's home, a DTV tech swapped clients around and came to the conclusion that the TV must have been causing the problem. I don't remember whether HDMI control was on or off.
A good answer is easier with a clear question giving the make and model of everything.

Ernie, i think that this will help.
I would love to give an absolute answer, but........

So tell me what the relay has to do and a little step by step.

You gave me enough information to buy your product, but not how to use it.

OK TOM.
Here is how it works.
The HDM-VCT is a black metal box the same size as out Original DAD, on one side is a two port Phoenix plug. Inside the VCT is a processor, TMDS Voltage/Current injector* and a micro relay that recognizes contact closure.

Using a pair of wires connect the Phoenix plug to a relay on your control system.
Every time you turn off the system "open" the relay on your control system (this for all purposes disconnects the HDMI cable from the source).
Every time you you turn on the system close the relay (last step of macro), this will force a reinitialize of the EDID (solving your problem).
It is also recommenced that you do this every time you change sources.

* This TMDS Voltage/Current injection also resolves issues that we are seeing where the source (due to firmware update) are demanding more current from the displays.
This is happening on DirecTV and CATV STB's that are connected with thin HDMI cables, Active HDMI cables and longer HDMI cables. The typical symptom is an HDCP Failure indicator (it is NOT HDCP), no picture or major color shifts.

How is this different from the AIO?

The AIO adds to that the Capacitance stripping capability of the DAD, JR and the new JR Plus.
it also fixes issues with some HDMI 2.0 chipsets where the EDID "0" signal is not recognized because the voltage does not drop low enough. .9V is the typical "0" voltage, but some devices require .6V. The JR Plus and the AIO drop it to .4V.

In the absence of a full blown control system with relay contacts, could a local 3X1 or 5X1 switcher be used to disconnect and reconnect, and accomplish the same thing? Or is the DirecTV power problem still going to rear its ugly head?

I do not know if this is possible. The videos sound awesome, but it is also possible that we may have to view ten videos, and try to figure out which device is the best to address a given problem. Is it possible to create a flowchart with symptoms, that lead us in the direction of the best device for that particular symptom? Perhaps there would be a couple troubleshooting steps in between the symptoms and the ideal device.

In addition to being a very real help to technicians in the field, it likely would aid in the sale of many more fantastic electronic gadgets for you!

A switch will not fix this issue, most keep the hot plug active to speed switching.

However I do have a unit coming (sadly CEIDA) that is an IR connecting block with a built in relay with code learning for Open/Close to provide a cost effective answer to this control issue.
