No signal to TV from Express 4k+

My Express 4k+ (3941x) will power on but will not work properly. I have rebooted the device several times. The screen with the dancing “R-O-K-U” will appear on my TV when the device is powered on, but when the device should go to the home screen, the display shows “no signal” instead.

I have tried using the device with two different HDMI cables in all three of the HMDI ports on the TV and get the same results. I have also plugged our different Roku devices into the TV and they work properly.

Pressing and holding the factory reset button on the back of the device does not change anything.

I am also able to find our other two Roku devices using the Roku mobile app but I cannot find this Express 4k+ with the app. This makes me think there is a hardware issue with the device related to its network connectivity.

    If you're using the TV's USB port for power, try the supplied power adapter (or vice versa, for that matter).

    I am having the exact same problem as you are/were. Did you ever solve it?

    Thanks, Patty

      Hi Watcher4now,

      Thanks for your post.

      May we know how you are powering your device? Also, what provided fixes have you tried so far? Do you happen to have another TV that we can hook the Roku Express into and see if the same issue occurs?

      Please keep us in the loop.

      Regards,
      Janadee

        Hello,

        Thank you in advance for trying to solve my Express 4K+ issues. I purchased the Roku in July 2022. I started having issues within a few months. When I would attempt to watch a program, the picture would flash on/off. I would unplug the HDMI from the TV. When I plugged back in the program would come back on and work fine. I erroneously thought my TV was getting too old (Samsung 2009). Then I started getting the low power message from Roku. I would unplug the TV and the ROKU. After I plugged all back in it would work. Now the message is NO signal from HDMI input the Roku is plugged into. I have tried changing the HDMI cord, plugging into other TV HDMI inputs and replacing the USB cord. I have plugged the USB into the TV and into an electrical outlet. I finally  connected an older ROKU 3 I have into the Samsung 2009 and it works perfectly. I connected the Express 4K + into a newer Visio smart tv. It gets stuck at the dancing ROKU letters. Then a message appears that there is no signal from the HDMI the Express is plugged into. I have tried a factory reset but the blue light just continues to stay lit..no flashing light.
