finally finish setup my Onn Roku tv. Not getting any video on the screen. I have picture when going threw apps and setup. But no video on TV mode or streaming. The sound is working so I know the TV is on. Took a video and picture of it but not sure how to post it on here. Its the Onn Roku 50" 4k under TV. Model number 100012585
Can you please provide more information about the issue you are experiencing? Is this issue happening on a specific channel or does it happen regardless the channel you are streaming? Have you tried removing the channel(s), restarting your TV, then adding the channel back to see if that resolves the issue?
With more information we will be able to assist you further.
