It might be a defective HDMI cable. Either that, or a defective HDMI port. Try different cables and ports and see if that will solve the issue. If not, then sure I would say that the entire device unit is defective. But as was stated in the above post, you could probably either check how your Roku device is powered. If it’s connected through the wall outlet and not the TV’s USB port, then you could probably return it for a replacement if you bought it direct from the Roku online store.
I’m into videotapes and old electronics stuff, including extenders, converters and analog 4:3 TV sets (which are obsolete these days), and Miss Bianca is my favorite character in Disney’s The Rescuers (1977) and its sequel, The Rescuers Down Under (1990). I am not a Roku employee, only a user like you. ~ Jordan
