The main Fios STB is hooked up to an old toshiba and works without issue. Tried this STB w/ 2018 Vizio E50-F2 TV and couldn't get the handshake. Was able to get it one time only w/ the Mini and can no longer get it. HDMI no signal. I have the TV and boxes set up for CEC, HDMI, and HD. All settings are correct but can't get the handshake w/ the Vizio TV. Switched the boxes with the TV. Everything works with Toshiba nothing with vizio. Tried all combinations of plugging/unplugging & changing the order of turning devices on. HDMI cables are new and certified for 4K ultra HD. A 3/27 firmware update by Vizio seemed to cause HDMI no signal issues that weren't there before. Can't get a tech out due to Covid. Reset TV to factory settings, doing soft reboots, etc. It worked one time and I had the best TV quality ever for 1 night only. Now back to No Signal. Tried removing the Mini STB and re-adding it to the network. Any suggestions for getting this to work again?
