Quick Answer
If the Roku remote app cannot turn on TV, first identify whether you have a Roku TV or a Roku streaming device. Roku TV power depends on model, standby, firmware, and mobile app control. Roku Stick and box power often depends on HDMI-CEC, the TV, the receiver, and whether the streaming device still has power while the TV is off.

Roku TV vs Roku Stick
| Device | Why Turn On May Fail |
|---|---|
| Roku TV | TV may stop listening in standby or block mobile app control |
| Roku Streaming Stick | Stick controls the player, not always the TV hardware |
| Roku Express / Ultra | TV power may depend on HDMI-CEC through the HDMI chain |
| Physical Roku remote | Some physical remotes use IR or TV-control features the app cannot copy |
Step-by-Step Fix
- Confirm whether the saved device is a Roku TV, Roku Stick, Roku Express, Roku Ultra, or another Roku player.
- Turn the TV on manually and confirm normal Roku navigation works in the app.
- On Roku OS 14.1 and later, enable Settings > System > Advanced system settings > Control by mobile apps.
- For Roku TV, check TV power, standby, and network wake settings.
- For Roku streaming devices, enable HDMI-CEC on the TV and receiver.
- Make sure the Roku streaming device still has power when the TV is off. Some TV USB ports turn off with the TV.
- Restart Roku, the TV, and the router if control is inconsistent.
What the Result Means
| Test | Meaning |
|---|---|
| Navigation works while TV is on | The app is connected; power is the limited part |
| Roku disappears when TV is off | Standby or USB power may make Roku unreachable |
| Roku Stick wakes the TV sometimes | HDMI-CEC is partially working but depends on the TV chain |
| Physical remote power works only | The physical remote may use IR or TV-control setup |

Roku Turn On FAQ
Is this a bug if only the power button fails?
Not necessarily. If navigation and app launching work while Roku is awake, the local remote connection is working and the power behavior is likely device-specific.
Does internet matter for Roku power?
Local control needs local network reachability. Streaming content needs internet, but the power issue is usually standby, HDMI-CEC, or mobile app control.
Should I use the physical remote for power?
Keep the physical remote available for fallback power, first-time setup, Wi-Fi recovery, and TV settings.
