Newbie/First post. I have a 4k Vizio M65 connected to a Onkyo TX-RZ710 which I've been very happy with for the last 2 years. So I'm watching TV one night & the screen goes completely black. I try to change channels and nothing, just a black screen. I pick-up the Vizio remote & select the "INFO" button & in the rectangular box
that shows input (1080p, 2160p) is blank. I do some basic troubleshooting removing the Onkyo & the Xfinity box and since the Vizio is WiFi I go to a Amazon Prime 4k
show and the picture is indeed 4k selecting "INFO" on the Vizio remote. I find the problem is with the Onkyo RZ710. When I replaced my old 1080p monitor with the 4k
Vizio, I selected 1080p -> 4k Upscaling on the Onkyo RZ-710 so the receiver would "Upscale" any 1080p programming through the Comcast/Xfinity box. SO, if I change the 4k Upscaling selection to "OFF" all works fine EXCEPT no 4k. Off means 1080p or less. SO, I call the Onkyo support line & the guy tells me the 4k logic is toast. (We already knew that.) SO I'm in Georgia & the support guy tells me I have to send the unit to a repair facility in Florida. (Lakes Electronics has the worst customer service & I question the expertise because when I told the bench tech the problem he was unfamiliar with 4k Upscaling.) SO, after 3 months I get the Onkyo TX-RZ710 back. If you guessed it was NOT repaired, you would be correct. SO, I'm talking to Onkyo support again & they said they would get back to me!!!!
Any ideas?
