Hisense 4k UHD Roku TV, turned it on tonight and only has a black screen. I did the remote sequence to reboot/restart the TV and it did not solve. I unplugged the TV for 30-60 secs and it did nothing. I unplugged for longer, about 10 minutes, it did nothing. But instill have audio, i can hear the menu when trying to navigate. Had the TV for only about 1.5-2 years..
Thanks
