I have a Samsung(UN5MU8500FXZA) Smart UHD 4k TV, Everything worked fine until I had an outage about a month ago. Since the outage, I have had Blackscreen with Xfinity. I have:
Restarted my box over 20 Times
Done Multiple System updates
Made sure my TV had updates
Got a new cable box
Had a tech out
The Xfinity Service works with other (old TV's), that i bring out
The Tech told me it was a handshake issue
we got it working for 1 day( until I turned hte TV off)
It has been blackscreen since then
other devices and appss still work including (other HDMI sources as well)
Everythingg but Xfinity
I have seen these issues in other forums back in 2018 & 2019
Does anyone know what can mix this?
