Hi, We have had great success with Roku Express HD since purchased in 2019. However, just recently during streaming any service, the image is sometimes ghosting with rapid image movement and not as clear as usual and this wide set of persistent faint vertical lines shows up everywhere including the home screen. The sound is perfect and there is no hesitations in streaming. We get 6Mbps down load where the TV is. The older Sony Bravia 1080P HD TV works fine on all cable stations with no problems. Software shows up to date and NW connection registers as "GOOD" when tested. We rebooted the Internet Router and restarted Roku. Any ideas? Can a Roku express fail? THANKS
Any electronic device can die, including your TV.
Have you tried connecting your Roku to a different HDMI port on your TV? Tried a different HDMI cable? Tried connecting it to a different TV?
