I received my Roku Stick Extender and have made sure that all connections are snug.
However, the picture now keeps flickering. It's like there is a loose wire or bad connection somewhere.
It's extremely irritating !
Thanks for the post.
Have you tried using another HDMI port to see if that resolves the issue? For troubleshooting purposes, have you tried plugging your device into another TV to see if you are experiencing the same issue?
Please keep us posted.
