I have a 4K HDMI 1x2 splitter that depends on the HDMI connection for power. I have the two outputs connected to two HDMI inputs on my Vizio TV. The input on the splitter is connected to my C61-700 4K receiver. Before I connect to the C61 the two monitoring lights for output are brightly lit. When I connect the C61 the input lights but dimly. The two output lights also stay lit but change to dim. And I get no signal passthru. This tells me something is off on the C61. A setting perhaps? Any knowledge or experience with this?
