Can you please explain this? In 3 TVs for me, the hdmi port of the tv to which my avr hdmi out was attached have become dysfunctional. All power connections have been thoroughly checked. All hdmi cables have been updated. That leaves my avr itself and splitter, both of which are under service to rule out any issues. The same splitter feeds into my projector which should have had hdmi issues in case the splitter was the culprit, since a projector I assume is a more sensitive pence of equipment. I am a bit flummoxed here on the hdmi issues. Interestingly, direct hdmi out from avr to the mi tv doesn't work whereas i get a display if routed through the splitter. Makes it even more confusing. Maybe best to take the full refund offered by Xiaomi. I echo the sentiments above on their customer service though - its been stellar. This is a significant part of a big ticket purchase.
