Are you able to share the specific TV model?
From TV itself: Sansui S55VAUG. From System info within tv menu: Settings: Device Name: GoogleTV8931 Model: Apollo Premium 4KTV
from cat /sys/class/drm/card0/card0-HDMI-A-1/edid: binary stuff with words 'AndroidTV' embedded. TV's only about 6 months old and MicroCenter offers them. Steve
