How do I fix a black screen on an onn Roku TV?

Reviewed by John Porter, Editor ·

Answer

Start with a full power cycle: unplug the onn Roku TV for 30–60 seconds, then restart from Settings > System > Power > System restart if menus are reachable. Update software, test apps again, and use the hardware reset only if the screen stays black.

Before you start: stop right away if…

  • A factory or hardware reset removes saved networks and app sign-ins.
  • If the screen stays black with no backlight and no startup sound after power cycling, unplug and seek hardware service—do not keep forcing resets.

Follow these steps

  1. Power-cycle the TV

    Turn the TV off, unplug it from the wall for 30–60 seconds, press the physical power button on the TV once if it has one, then plug back in and power on.

    You should see: The Roku home screen or startup logo returns instead of a permanent black screen.

  2. Run a system restart from menus

    If you can open menus, go to Settings > System > Power > System restart. After reboot, open Netflix and Apple TV and compare whether one works better than the other.

    You should see: Menus stay usable and you know if the issue is one app or the whole TV.

  3. Check for software updates

    Go to Settings > System > System update > Check now (wording may vary slightly). Install any update, restart, and retest the apps.

    You should see: The TV reports it is up to date and apps launch more reliably.

  4. Use hardware reset if the screen goes black again

    If menus disappear again, follow the onn/Roku hardware reset for your model (usually a pinhole or guided reset in the manual). After reset, reconnect Wi‑Fi and sign back into apps.

    You should see: The TV boots to initial setup or home screen and remains controllable.

Extra tips

What to look for: Whether the Roku startup sound/logo appears; backlight on with no picture; ability to open Settings; failures limited to Netflix/Apple TV versus all inputs.

Before you change anything: Confirm the TV has power and the remote batteries are fresh. Try a different HDMI input or built-in app to see if the panel works. Note any recent power outage or update. A factory/hardware reset can remove accounts and network settings.
