To complete your set top box setup, connect the box to the right signal source, run its HDMI output to your TV, connect power, then select that HDMI input with the TV remote. What happens next depends on your box: an aerial receiver tunes channels, a provider box may need activation, and a streaming player connects to the internet.
Which Connection Does Your Set Top Box Need?
| Box type | Signal or network input | Next setup step |
|---|---|---|
| Aerial / terrestrial receiver | Compatible aerial into RF IN | Select region and scan channels |
| Cable-provider box | Provider-approved connection | Follow provider activation instructions |
| Satellite receiver | Compatible dish feed into SAT / LNB IN | Follow receiver and provider setup |
| Streaming player, such as Roku Ultra | Wi-Fi or supported Ethernet connection | Connect network and activate account |
Match the receiver to your service and country before buying. An aerial receiver, satellite receiver and streaming player are not interchangeable just because they all connect to a TV. Check the labelled ports and your model’s manual.

Understand Your Receiver Before You Connect It
A set top box takes its supported signal or streaming service and sends picture and sound to your television. Look up the exact model before choosing accessories: some boxes receive aerial broadcasts, others use a cable or satellite service, and streaming players use internet apps.
Recording, catch-up apps and USB playback are model-dependent features. Check your manual rather than assuming every box supports them.
Streaming Option: Roku Ultra
The Roku Ultra below is for internet streaming apps. It is not an aerial or satellite tuner and will not replace a provider’s required receiver. Check app availability in your country and any subscription requirements before buying; you do not need a new player simply to connect a working receiver.

Follow Roku’s setup instructions for its network and activation steps. Check the included accessories before adding a separate HDMI cable to your order.
Check Your Cables Before Buying Accessories
Lay out the box, its supplied power adapter, remote and batteries. Check the packaging for an HDMI cable before ordering one: some receivers include it. Measure the route between the box and TV, allowing slack so the cable does not pull on either socket.
- HDMI: use this when both devices have HDMI ports. It carries picture and sound.
- Aerial or provider cable: match the connector and service to your receiver. An Ethernet lead cannot replace an aerial lead.
- Ethernet: optional for a box with a supported LAN connection when you want a wired route to the router.
- Older TV: check for matching SCART or composite outputs on the receiver. An HDMI-only box needs a compatible powered converter for an analog-only TV; a passive cable is not a universal solution.
Replacement HDMI Cable: Amazon Basics 6 ft
This listing specifies a 6-foot HDMI cable supporting 4K at 60 Hz. It is an option if your supplied lead is missing, damaged or too short. Skip it if your existing cable works, your devices lack HDMI, or you need a longer run.

Step-by-Step: Connect the Box to Your TV
- Position the box. Leave its vents clear and keep the equipment powered off while attaching cables.
- Connect its source. For terrestrial TV, connect the aerial to RF IN or ANT IN. For cable or satellite, use the input and feed specified by the provider. For a streaming player, skip aerial cabling and prepare your Wi-Fi details or Ethernet connection.
- Connect the TV. Run HDMI OUT on the box to an HDMI IN on the TV. Note the TV port number. If using analog connections, both devices must support them.
- Connect power. Use the adapter supplied or approved for your exact model, then turn on the box and TV.
- Select the TV input. Use the TV remote’s Input or Source button to select the port you used, such as HDMI 2. The box’s remote usually handles its own menus; it may not control the TV input until configured.
For an aerial receiver, the Freeview setup guide illustrates the separate aerial and TV connections. Socket labels and tuning menus vary by model.
Initial Power-On: Tune, Activate or Connect
Once the box’s startup menu appears, follow its on-screen prompts. Choose your language and region if requested. Do not run a channel scan on a streaming-only player expecting it to find aerial channels.
- Aerial receiver: select the appropriate country or region, scan for channels and save the results.
- Provider box: follow the provider’s activation process; a generic channel scan may not provision your service.
- Streaming player: connect to Wi-Fi or supported Ethernet, install prompted updates, and complete account activation.
No Signal, No Channels or No Sound?
| What you see | Check first |
|---|---|
| TV says No Signal; no box menu | Box power, selected TV input and HDMI connection |
| Box menu appears, but no broadcast channels | Correct aerial/provider feed, receiver compatibility and tuning or activation |
| Streaming menus work, but apps buffer | Network connection; try wired Ethernet if supported |
| Picture but no sound | Mute and volume on both devices, then the box’s audio-output setting for your TV |
| Remote does not respond | Batteries, clear line of sight where needed, and the model’s pairing instructions |
If the startup menu never appears, test another TV HDMI input or a known-working cable before replacing the box. If the menu works but channels do not, investigate the signal source or activation rather than buying an HDMI cable.
Frequently Asked Questions
Do I need internet for set top box setup?
A terrestrial receiver can tune aerial broadcasts without internet, although catch-up apps need a network connection. Streaming players need internet for setup and streaming. Provider boxes have their own requirements.
Which TV input should I select?
Select the HDMI number you connected the box to, using the TV remote. For a compatible analog connection, choose the matching AV or SCART input.
Can I connect a set top box and DVD player to the same TV?
Connect each device to a separate compatible TV input, then switch inputs with the TV remote. If the TV has only one HDMI input and both devices output HDMI, use a compatible HDMI switch. A splitter serves a different purpose.
Will an HDMI cable work with an older TV?
Only if the TV has an HDMI input. Otherwise use matching analog connections supported by both devices, or check whether an appropriate powered converter supports your equipment. A passive HDMI-to-RCA lead is not a general solution.
The box-to-TV connection is working. Check the aerial or provider feed and receiver compatibility, then follow the receiver tuning or provider activation instructions. A streaming-only player does not scan an aerial for channels.
Black Friday buying tip: List the ports, cable lengths and accessories you actually need before comparing offers. Check what comes in the box; an extra HDMI cable or a replacement player is wasted money if your existing setup already works.
How this guide was checked: Connection steps were compared with official Roku and Freeview guidance; product identity and cable specifications were checked through the affiliate plugin’s listings. This is a setup guide, not a hands-on product test.
After Setup
Test one channel or app, check sound, and confirm that both remotes do what you expect. If your receiver offers recording or a programme guide, use its manual to configure those features. Install official updates when prompted and keep the ventilation openings clear.
Start with the cables you already have. If something fails, use the symptom table above to separate a TV-connection problem from a broadcast or network problem before buying replacements.
