Tv flashing on and off


Recommended Posts

I don’t think this is a Control4 problem but I thought perhaps maybe somebody could help me with this . Whenever I watch TV in the bedroom with dish theTV flickers off and on about every five seconds. It actually makes a loud crackling noise at times. If I watch YouTube or Netflix or any other app it works fine. The connection for the master bedroom is from the monitor 2 out  through a balun to the master bedroom tv. Also the outdoor theater does the same off and on when watching dish but works fine when watching a movie through Zappiti. This is connected through the receiver zone 2 output through the Balin to a receiver in the garage that operates the outdoor theater. The steps I have taken so far to try to fix this is upgrading all the HDMI cables and checking the settings in the dish and marantz receiver. So if anyone could give me any suggestions I would appreciate it thanks

Is this VIA the same set top box? If so, it sounds like the tuner might be going in it.

I forgot to mention that whenever watching dish in the main theater room it works fine. Usually when watching an app it’s through the Samsung TV.

Could be balun issues?

The odd thing is the zappiti goes through balun to outdoor theater works fine for playing movies .The condition exists only when trying to play dish in both master bedroom and outdoor theater. There are two seperate balun one master bedroom and one for outdoor theater. It would be odd for both Balun to be defective  when they let other video sources play. But thanks for your ideas. I’ll continue to troubleshoot but it’s getting irritating. Thanks for your help

So receiver zone 2 to balun to another receiver? Also a good chance it's an HDCP/EDID issue. Different balun may work, or may need something to bypass the receiver EDID (HDMI splitter with settable EDID or HDMI audio extractor)

If you're having issues on BOTH TVs, there is the possibility that the issue is the Dish box too, or that the EDID is an issue right of the settop box - in the latter case, you can try use a single splitter/extractor directly on the box to the first receiver.

That's what I'm leaning towards it's trouble with the dish box. Sorry to repeat myself but I just don't understand why other video sources work, zappiti ,bluray player. I could eliminate the balun to the master by a long hdmi cable but unable to the eliminate the balun that connects the outdoor theater. Outdoor theater works fine which is  primarily used for the movies. Really don't watch much TV outdoors. But on rare occasions in the fall I like to watch football out there. I will try your suggestion and thank you so much for your replies.
