Hello,
We have recently completed a simple upgrade to our in house church TV's and we are experiencing a problem. First, some quick background...
Previously and least important our setup was as follows to each TV.
ATEM 1 M/E > Program out > SDI to Analog Mini Converter > TV Modulator > TV x4 (analog was stanard RG6 coax).
Current setup as of the upgrade date of 7/11/16 as follows:
ATEM 1 M/E > Program out > SDI Distribution Mini Converter > SDI - HDMI Micro Converter > TVx4 (One Micro Converter at each TV).
Problem:
After a few minutes of being on, the sound signal coming from the TV puts out a static/white noise like sound, almost like a digital interference of some sort. It doesn't do it constantly. It will stop for a few seconds and pick back up for a minute or two. Here's what I have done in way of troubleshooting.
I have confirmed that it isn't a matter of signal loss or interruption from the long cable runs. The issue is the same across all TV's/converters. To take that method of thought a step further, I have a TV in our Media Booth at the church not 10 feet from our switcher, I ran a program out directly to one of the Micro Converters that I removed from one of the TV's (totally bypassed the distribution converter), and then out HDMI to the TV's from the Micro and the problem reproduced itself after a few minutes.
I have pulled the analog sound input from the switcher, and while the main incoming sound signal does stop and obviously goes away, the static noise is still there.
I can disconnect the HDMI from the converter, and plug it back in after a few seconds and the problem instantly returns.
I can disconnect the SDI connection and plug it back in after a few seconds and the problem will go away for anywhere from 5-10 minutes and then return.
TV Types: (3) 47" Vizios, (1) 32" Vizio and the test TV in the media booth mentioned above is a 48" Hitachi, 2016 model. Same results on all TV's.
The only other common denominator is the HDMI cables. I am running 3FT Vanco HDMI cables (High Speed with Ethernet) from each Micro Converter to the TV's. I used a 10FT Vanco to test the connection on the TV in the media booth.
There you have it. I tried to sum up as much as I could but provide quick and pertinent information. I have attempted to plug the Micro Converters up to computer using the latest version of the converter software and there's not much in the way of settings to adjust, other then the "Clip Video Output to Legal Levels" setting, and it has nothing to do with audio (for arguments sake, I did test it with this setting off - same problem!).
I've made bold the areas that I feel the problem is likely to exist. Either the SDI connection or the HDMI cables... However, the SDI method we are using is the same that we have running all of our long run projectors, the SDI to Analog converter, and the SDI to our DecLink to our live stream box and we have had zero problems. The sound issue only lies with the TV's.
Sorry for the long post, again, wanted to provide as much detail as possible and minimize the number of questions. Please feel free to ask though and I will give more detail if needed in any area.
Any help or suggestions are appreciated. Thanks in advance.
