Reply To: MXQ box keeps shutting down my TV during movie play…why?

I have a decoder plugged in on my tv on HDMI1. When I plug my MXQ 4K tv box into my tv on HDMI2 or 3 the tv box and decoder start to flicker on the tv screen. Both shows clear picture for 2 seconds then off for 2 seconds and keep on repeating the sequence. I can unplug any one and just have one connected on the tv and it works 100%. I tried to connect them to a splitter box and just have one HDMI cable into the tv but still had the same problem. A different MXQ 4K box on 2 other tv’s is doing the same thing.
Do you have any advice for me please.
