Just looking for some insight.
I have a client with a New Samsung Q80(His LG TV took a dump),The equipment lives in a closet: marantz NR1510, Roku Ultra and Spectrum Cable. There was a piece of Cat5e ran when the house was built(100feet) to the tv. We had a set of Vanco HDBT extenders in there that worked fine for 1-2 years.
With the New Samsung TV, it will cut out(blue screen of death) in the middle of the show. The customer has to go into the closet and either pull the HDMI or power from the extender. We recently re-terminated the cables and put in a new set of Vanco EV4K2006. Same problem.
I have the resolution fixed on the cable box and have the Input signal plus was turned off on the TV.
Let me know if anyone else has seen this before. I love losing money on problems like this

Switch to AV PRO Edge and you will fix your problem. Great support and 10yr warranty. Everytime I went cheap with Vanco it bit me in the butt.

I don't think switching the brand extender will help in this situation.
The key is in this statement "customer has to go into the closet and either pull the HDMI or power from the extender".
'THAT' is the classic sign of a hot plug issue. The Samsung TV is probably what caused this to creep up but could be the Marantz receiver as well. Either way, you need a device to interupt the hot plug (electrical way of going to the closet and disconnecting & reconnecting things).

Luckily Brent has a solution: [Link: metrahometheater.com]

You will only need to figure out how you are going to trigger the relay input. Either by control system or maybe a switched wall wart, etc...

FWIW, I replaced a set of Snap extenders with AV Pro Edge and they solved the same problem for a few days. System worked on the Snap extender for a year prior to spazzing out.

I don't know what the hell Samsung did but it is starting to become a huge problem. The distributed video (or extender), Marantz AVR and ~1 year old or newer Samsung tv comb is wreaking havoc (and making us look like a bunch of monkeys doing you know what to a football).

It is odd as I have numerous combos, some in the same house, that are fine.

Samsung panel/Crestron DM = no issues
Samsung panel/Marantz AVR being fed DM via HDMI direct = No issues
Samsung panel/Marantz AVR/any HDMI extender = Problem
LG (or Sony) panel/Marantz AVR/any HDMI extender = No problem (so far)

The breakdown is caused by the AVR/extender combo but it isn't the AVR's fault per se, it is the tv flipping out.

We are almost 20 years in to HDMI as our primary video source. Why are we still having problems like this?

This isn’t really directly related, but it may help you down the road a piece.

I had a Samsung TV feeding ARC through one of Snap/Sonos‘s B260 ARC extenders. The sound kept flipping back-and-forth from the TV to the Sonos amp, rather than the Sonos amp doing all the TV sound.

Because I was desperate, I tried an AVPro HDMI extender with ARC, and the problem was solved immediately.

On yet another peripheral installation, I used the same AVPro extender, because I just wanted to feed the cable box from the closet to the TV, and then I needed the ARC backfeed to the Sonos amp, also in the closet. Unfortunately, in that situation, it required two extenders, one for the audio and video feed from Comcast to the television, and one for the ARC backfeed to the Sonos amp.
