1. Work out which kind of Roku you have
Roku is two different problems wearing one name. A Roku TV is a television with Roku built in, and it has a physical button. A Roku player — a stick or a small box plugged into someone else's TV — has no power button of any kind. Before you go looking, decide which one is in front of you, because the answers do not overlap.
| Device | What is on the device itself |
|---|---|
| Roku TV (TCL, Hisense, onn, Philips, Sharp, and Roku's own Select and Plus series) | One physical button. Its position is set by whoever built the television, not by Roku: under the bottom-right corner, at the bottom centre, or on the back panel. On most sets it only switches the television on and off. |
| Roku Streaming Stick and Streaming Stick 4K | Nothing. No power button, no menu button. The stick powers up when the television's HDMI port or USB socket gives it power, and it has no way to be operated by hand. |
| Roku Express and Premiere | A pinhole on the body. It is a reset, not a power button — see the warning below. There is no manual control of any kind. |
| Roku Ultra and Streambar | The Ultra has a reset button and, usefully, a button that makes a lost remote beep. A Streambar has real power, volume and input buttons on the bar itself, because it is also a speaker. |
The pinhole on a Roku player is not a hidden power button. Hold it down and the device factory-resets: it forgets your Wi-Fi, your accounts and your apps, and comes back on the setup wizard. If you have lost the remote, that is the worst place you can be, because the wizard cannot be driven from a phone. Never press it while you are remote-less.
2. What the one button on a Roku TV actually does
This is where Roku differs from Samsung and LG, and where most advice quietly misleads. On a Samsung or an LG the hidden control is a slow but complete remote: it opens an on-screen menu and you can reach every setting with it. On almost every Roku TV it is not a menu at all.
- One press when the set is off — the television turns on. This part always works.
- One press when it is on — on most Roku TVs the set turns off again. No menu appears.
- Settings, volume and inputs — generally not reachable. A handful of models cycle inputs on a long press, but it is not something to count on.
- On a Roku Ultra — the button on the box finds the remote by making it beep. It does not control the television.
- On a Streambar — power, volume and input are all there as real buttons, which makes it the one Roku you can genuinely operate by hand.
So on Roku the phone is not a convenience, it is the main route. On a Samsung or an LG you can reach every setting with the hidden control if you are patient; on a Roku TV you cannot, and everything below is about getting the phone working instead.
3. The phone path — and Roku asks for nothing
Roku answers plain web requests on your own network, on a fixed port, with no authentication in front of them. Roku's own app uses that interface and so does every third-party remote app. This is the best thing about Roku remotes and almost nobody mentions it.
Compare what the first connection costs you on each platform:
- Roku: nothing at all. No code to type, no permission box to approve on screen, no account to sign into, nothing that expires and has to be done again. The app finds the device and it works.
- Samsung and LG: a permission box that has to be approved with a working remote or the hidden control — which is exactly what you do not have.
- Android TV and Google TV: a code shown on the television that you type into the phone.
- Typing is better on Roku, too. Roku accepts literal characters, so a search box can be filled from the phone's own keyboard instead of pecking letter by letter across an on-screen grid.
Here is the honest limit, and it is the one thing the cheerful guides leave out: all of this needs the Roku to be on your Wi-Fi already. On a brand-new or factory-reset Roku TV the setup wizard asks for your network before anything else, and the single physical button cannot answer it. If the set has an Ethernet socket, a cable gets it onto the network and the phone takes over from there. If it does not, you need a remote once — see the last section for which one.
4. The two switches that let something else wake it
A Roku that has gone to sleep can drop off the network entirely, and then the phone cannot reach it. Two settings fix that, and they are worth turning on while you still have a working remote rather than after you have lost it.
- Open Settings → System → Power and turn on Fast TV start. This keeps the network side awake in standby, which is what lets the phone switch the device on. Not every model has it.
- Open Settings → System → Control other devices and enable 1-touch play. This is Roku's name for the HDMI-CEC feature other makers call Anynet+ or SIMPLINK.
- On a Roku player the same setting lives in the same place, and it is what makes the stick turn the television on when you start watching.
- Test both: press a button on a games console to see whether the television wakes, and separately try switching the Roku on from the phone after it has been idle for a while.
Fast TV start costs a little more power in standby. That is the whole trade, and it buys you a device that a phone can wake — which matters a great deal more the day the remote disappears down the side of the sofa.
5. Inputs behave like apps, which nothing else does
On a Roku TV the HDMI sockets are listed on the home screen beside Netflix and YouTube, under whatever names you gave them. The control interface treats them the same way, so a phone can jump straight to a named input in one tap instead of stepping through sources one at a time.
Two consequences worth knowing, both of them measured on real hardware rather than taken from a manual:
- A named input is one tap away. Because inputs are listed like apps, a phone can go directly to the HDMI socket your console is on. Televisions that only expose a source key have to cycle through every input in turn and hope.
- The names come from the television. Rename an input on the Roku and the phone shows the new name. If the list looks wrong, fix it on the television rather than in the app.
- A Roku player cannot switch the television's inputs. A stick is a guest on somebody else's HDMI socket; it can turn the set on through 1-touch play, but choosing between HDMI 1 and HDMI 2 is the television's job, not the stick's.
6. Which remote to re-pair, and which one to buy
Roku ships two quite different remotes and the fix depends on which one you have. Look at it before you do anything: a simple remote has no microphone and no pairing button; a voice remote has both.
- A simple Roku remote is infrared and has nothing to pair. If it has stopped working, it is batteries, line of sight or the remote itself — there is no pairing to lose.
- A voice remote connects over the air and can lose its pairing. Open the battery door, hold the pairing button for about five seconds and wait for the light to flash. If no light appears, unplug the Roku for a few seconds, plug it back in, wait for the home screen and hold the pairing button again.
- If you are buying your way back in, buy the simple infrared one. It needs no pairing, which means it works before the device is on Wi-Fi — and it is cross-brand, so a Roku infrared remote drives a TCL, a Hisense or an onn Roku TV alike.
That last point is the practical heart of this page. A phone cannot complete setup on a factory-reset Roku TV, and a voice remote has to be paired through a screen you cannot reach. The cheap infrared remote is the only one that works from a cold start, which makes it the thing to keep in a drawer.
