Your Roku usually keeps restarting because of a power , overheating , or software/settings issue, and you can usually fix it at home by working through a few simple checks.

Quick Scoop: Why your Roku keeps restarting

Most common causes reported in recent guides and 2025–2026 fix videos are:

  • Corrupted cache or minor software glitches.
  • Bad power source (weak USB power from TV, loose cable, bad adapter, faulty surge protector).
  • Overheating Roku stick/box or TV mainboard.
  • Problematic power‑saving or bandwidth‑saving settings that shut it down.
  • Buggy apps or recent software updates.
  • Stuck remote buttons or faulty HDMI devices attached to the TV.

Think of it like this: if your Roku isn’t getting clean power, is getting too hot, or its software is confused, it panics and reboots.

Fast fixes to try first

Do these in order; many people fix it in the first few steps.

  1. Do a proper power cycle
    • Unplug the Roku (or TV) from power at the wall.
    • Wait at least 60 seconds.
    • While it’s unplugged, press and hold the Roku remote’s power button (or any button) for 15–20 seconds to discharge it.
    • Plug it directly into the wall outlet, not a power strip if possible.
  1. Check the power source and cable
    • If you’re using a small Roku stick powered from a TV USB port, switch to the original wall power adapter and cable.
 * Try a different wall outlet and a known‑good USB cable/adapter that can provide enough current. Weak power is a very common cause of restart loops.
  1. Look for overheating
    • Feel the Roku or the back of the TV near the Roku hardware. If it’s uncomfortably hot, that’s a red flag.
 * Move it so it’s not crammed behind the TV, remove anything covering vents, and give it 10–15 minutes to cool.
 * If you ever see an on‑screen “device overheating” message, treat that as the main suspect.
  1. Disconnect accessories and HDMI devices
    • Temporarily unplug: game consoles, soundbars via HDMI‑ARC, streaming sticks, and any unusual USB devices.
    • Swap to a different HDMI port and/or different HDMI cable for the Roku or Roku TV sources.
 * Faulty HDMI handshakes can actually trigger reboots on some TVs and Roku models.
  1. Update system software (if you can stay on long enough)
    • Go to Settings → System → System update → Check now.
    • Install any pending updates, then restart from Settings → System → Power → System restart.

Deep‑dive fixes (when it keeps coming back)

If the quick steps didn’t stop the restart loop, try these more “surgical” fixes.

1. Turn off power‑saving features

Recent Roku and Roku TV updates added aggressive power‑saving and “bandwidth saver” features that can make the device shut off and restart more often than you expect.

  • Go to Settings → System → Power → Power saving. Turn off Auto power savings and similar options.
  • Also go to Settings → Network and look for “Bandwidth Saver.” Turn it off so Roku doesn’t shut itself down after idle time.

2. Clear cache / soft reset

Many step‑by‑step fix videos mention that clearing the cache or doing a soft system restart stops random reboots on otherwise healthy devices.

  • Use Settings → System → Power → System restart.
  • Some guides mention a “secret” remote sequence to clear cache before restart; this helps when the OS is glitchy after updates.

3. Check specific apps

If the Roku mostly restarts when you open or use one app (for example, Netflix or YouTube):

  • Remove that app.
  • Restart the Roku.
  • Reinstall the app from the Channel Store.

Buggy or corrupted app data can crash the system and force a reboot.

4. Inspect the remote

It’s unintuitive, but weak or flaky remote batteries can spam commands and contribute to weird behavior or restarts.

  • Put in fresh, good‑quality batteries.
  • Make sure no buttons are stuck down or pressed by something on the couch.

5. Factory reset (last resort)

When nothing else works, many forum threads and help guides recommend a full factory reset, especially if the device came out of the box with very old firmware that refuses to behave after updates.

  • Use Settings → System → Advanced system settings → Factory reset, or
  • Press and hold the physical reset button on the Roku / Roku TV (usually 10–20 seconds, depending on model).
  • You’ll need to sign back into all your apps afterward, so note any important logins.

If the Roku still reboots constantly even after a full factory reset and clean setup, that strongly points to a failing power board or internal hardware.

What people are saying in forums (2024–2026)

Recent forum discussions and troubleshooting posts show a few recurring patterns:

  • Some users fixed a reboot loop only after a full factory reset because their unit shipped with old firmware that didn’t update cleanly.
  • Owners of certain Roku TVs (TCL, Hisense, Onn) report that bad power boards or mainboards caused endless boot loops; in those cases only repair or replacement helped.
  • Others traced the issue to dodgy surge protectors or power strips that delivered unstable power; plugging directly into the wall made the restarts vanish.
  • A few threads mention that once overheating starts happening regularly, reboots become more frequent until the device is moved or repaired.

So in 2026, “Roku keeps restarting” is still a hot troubleshooting topic, but most everyday cases are still solved with power, cooling, and reset steps rather than buying a new device.

If it’s still stuck in a loop

If you’ve tried: direct wall power, different cable/outlet, cooling it down, disconnecting accessories, turning off power/bandwidth saver, updating software, and a factory reset—and it still restarts:

  • It’s likely hardware failure (power board, mainboard, or internal memory).
  • At that point, your realistic options are:
    • Contact Roku or the TV manufacturer for warranty or paid repair.
    • Compare the repair cost with a replacement Roku stick/box or TV.
