    Hi StevenCee,

    Thanks for the update!

    We are glad to hear that you were able to fix your Roku TV after restarting the system and installing the final update.

    For the cache, Roku does not have a cache, so there is no way to clear it. However, you can try these steps to improve your Roku's performance:

    Restart your Roku device:

    1. Press Home on your Roku remote
    2. Scroll and select Settings
    3. Select System
    4. Select Power. If you do not see a Power submenu, skip to the next step.
    5. Select System restart

    In either case, your Roku device will complete a system restart and hopefully return to normal operation after a moment. If it does not, continue to the next section.

    If the issue is persistent proceed with the next steps.

    Reset the network connection:

    1. Press Home on your Roku remote
    2. Scroll and select Settings
    3. Select Advanced System settings
    4. Select Network connection reset
    5. Select Reset connection

    After the network reset is done, your Roku device will restart and you will need to return to the Settings menu and set up your wireless network again.

    We hope these troubleshooting steps will help you to resolve your issue.

    Regards,
    Riamie

      Hi atozconstructio, Chytown,

      Thank you for bringing to our attention that your ONN Roku TV is only showing a black screen. We would be more than willing to assist you.

      Before we proceed, we would like to know the details below:

      • When did you start to experience the issue?
      • Did you receive a recent software update prior to this issue happening?
      • What are the troubleshooting processes that you tried in trying to fix the issue?

      In the meantime, we highly suggest you try the following.

      1. Unplug the ONN Roku TV from the power source
      2. Wait for 10 seconds and plug it back.
      3. If it does not work, please try to plug it into another power outlet.

      If the issue persists, we recommend that you contact the manufacturer of your ONN Roku TV, which is ONN.

      Please keep us posted.

      Regards,
      Riamie

        I'm having similar problems, since yesterday (and after being updated to OS 14), and on a TCL Roku TV, so I doubt it's something limited to just ONN TVs.
        It was working OK until late last night, when I again found I couldn't play trailers on the Roku Channel, nor could I play the movie itself. So I did a System Restart, tried again, and still no luck playing trailers or movies, then I tried the Roku Live channell, and nothing would play. Tried my OTA channels & even those wouldn't play! So I tried Netflix, and I could see their home screen, but when I selected something to watch, it wouldn't load & play it! 
        I checked my WiFi connection in that room, and it was working fine (about 200+Mbps), but now nothing was playing, no broadcast stations, Roku stations, Netflix, but I was able to get Pandora to play.

        This morning, NO Roku stations will play, just a black screen! My broadcast, OTA channels will play, but only audio, with black screen!  Something is wrong here, and the likely suspect is a buggy new OS14, as that is what was most recently installed. I sure hope your engineers can figure out what is wrong, and shoot out an update that corrects this, as it's just not working...

        Also, I'll ask again, for about the 20th time: Is there a way we can clear the cache?

        And I was contemplating doing a total reset, but sure don't want to have to re-download every app, then go through all the hundreds of channels, to select my Favorites, unless absolutely everything else has been tried. Is there some way we can save our settings, so if we do a total reset, we can just add it back, thus avoiding a tedious & time-consuming project in doing it all manually?  Every other digital device we use has a means of backing up important data, surely Roku has this functionality, no?  Especially considering how often all kinds of issues occur...
