Hi @ssmythe68,
Greetings from the Roku Community, and thanks for raising this concern directly with us!
We understand you're having a problem with the Roku Express 4K. We're happy to assist you. How are you powering your Roku device? Is it directly plugged into the wall outlet or on the power strip? Please make sure that all the cables are properly plugged in and firmly attached.
If the problem still persists, try switching HDMI outputs at the back of your TV.
We look forward to hearing from you soon, and let us know how it works.
Regards,
John
