Hello All. I have a Vizio V555-G1 TV with a ROKU Streamer HD plugged into HDMI3. Within the last couple of weeks, my HDMI-3 input will go blank. Nothing from the ROKU box, or so it appears. I have swapped the box with a streaming stick and everything will work fine for a while and then the same thing happens. No more input on HDMI-3. I've tried HDMI-1 and -2 with the same results. I have to believe there is some sort of issue of compatibility, but want to see if anyone knows of a solution. I take bot ROKU devices to my upstairs TV and they work fine. Thank you!
