I have similar issue since yesterday's update to 22.214.171.12474. The Roku starting showing black screen even after unplug power and plugging power back on. Performed a full reset which works to have something show on screen until after the setup procedure step where it is detecting my TV. This is where the screen turns black, I can hear the remote sounds, and at times I get the static screen briefly or a full no hdmi device detected. This is with my Streaming Stick+ plugged into soundbar. When I plug directly into TV, the Streaming Stick+ works. There seems to be some video auto detect issue for me. I would like to have this fixed to connect the Roku to my soundbar for better audio options (Atmos).
Roku model 3810X - Streaming Stick+ Device ID - 2139AD878399 SW ver - 126.96.36.19974 Serial # - YHOODP878399
same issue on my soundbar. not sure what to do. sending back to ROKU for a refund I guess since it will not work on my TV but every other device on it works perfect. I was so hoping it wouldn't suck... and it does.
