New TV Finds No Channels: Setup, Outlet or Antenna Fault?
Use the section map if you only need a quick answer. The full guide covers the diagnostic path, decision factors, practical next steps, and FAQs.

A New Screen Does Not Automatically Test the Antenna
When a new TV finds no free-to-air channels, first confirm that it is using its broadcast tuner, connected to the antenna wall outlet and scanning Antenna, Air or Terrestrial—not Cable, Satellite or an HDMI input. Then test the same outlet and fly lead with a television that previously worked.
That comparison separates a setup problem from an outlet or shared antenna fault. Avoid repeated factory resets or buying a booster until you know whether a usable signal reaches the TV.
If the outlet cannot supply a verified signal, use TV point installation and fault work in Brisbane.
Short answer
Connect a sound coaxial fly lead from the wall outlet to the TV’s antenna input, select Australia as the region, choose Antenna/Terrestrial as the source and run an automatic digital channel scan. If it finds zero channels, test a known-working TV and lead at the same outlet. If neither works, investigate the outlet and antenna system; if the old TV works, review the new TV’s tuner settings and support.
The ABC’s reception guidance distinguishes tuning and equipment checks from antenna-system faults and cautions that resets can remove saved settings.

Identify Which Part of the Setup Failed
| Result | Likely next focus | |---|---| | New TV works at another outlet | Original outlet or branch | | Old TV works on same lead and outlet | New TV setup, tuner or device | | Neither TV works on the outlet | Fly lead, outlet, branch or shared system | | No TV works anywhere | Shared antenna, cable, amplifier or external issue | | Scan finds some networks | Tuning, frequency-path or reception margin | | Streaming works but free-to-air does not | Antenna/tuner path; internet is separate |
Change only one component at a time. Swapping the TV, lead and outlet together loses the diagnostic value.

Eight Checks in the Right Order
1. Find the correct antenna input
Use the round RF input labelled Antenna In, RF In, TV In or similar. Do not connect the wall lead to a satellite-only connector where a television has separate inputs.
2. Seat the fly lead firmly
Check both ends and inspect for a bent centre conductor, loose plug, crushing or a sharply kinked cable. Compare a known-working short lead.
3. Select the TV tuner
Use Source or Input and choose TV, Live TV, DTV or Broadcast. An HDMI “No Signal” message refers to the selected external-device port, not the antenna tuner.
4. Set the correct country or region
Choose Australia during setup. Region settings can change the broadcast system and channel search behaviour. Follow the manufacturer’s Australian manual.
5. Choose Antenna or Terrestrial
If the setup asks between Antenna/Air/Terrestrial and Cable, choose the antenna option for Australian free-to-air broadcasts delivered through the property outlet.
6. Run digital auto tuning
Allow the scan to finish. Record the number of services found and test several networks. The TV channel rescan guide covers menu variations and the factory-reset boundary.
7. Compare a proven TV
Test a TV that previously received free-to-air services using the same lead and outlet. Then test the new TV at the proven outlet. This is the highest-value isolation step.
8. Check the wider property
Ask whether other TVs or neighbours lost reception. Check whether an amplifier power pack was unplugged during furniture changes. Record recent storms, roof work or cabling changes.

If the Old TV Works and the New TV Does Not
Recheck source, region and scan type. Update the TV software through its supported method where appropriate, then consult the manufacturer about the tuner.
Do not assume the old TV’s saved channels prove that it would find them in a new scan. If reception is marginal, one tuner may continue displaying stored channels while another cannot lock them. Measurements at the outlet can show whether the signal has sufficient quality.
A factory reset should be a controlled last setup step. Record picture settings, Wi-Fi details, logins and accessibility preferences first.

If Neither TV Works at the Outlet
Test another known-working fly lead. If another outlet works, the problem is likely the room outlet or branch. If every outlet fails, look upstream:
- antenna alignment or damage;
- main cable or connector;
- splitter or distribution fault;
- amplifier and power injector;
- external reception or broadcaster issue.
The ACMA’s TV reception problems and fixes recommends this system-level approach and identifies cable, fly leads, splitters, amplifiers and interference as separate possibilities.

If the Scan Finds Only Some Channels
Write down the network groups. Do not repeatedly rescan. Use the Government’s mySwitch service to identify the predicted transmitter and broadcast frequencies, then compare other TVs and broadcaster status.
Partial results can indicate:
- the scan ran while one service was unavailable;
- the antenna path is marginal at part of the band;
- a cable or connector has a frequency-selective fault;
- the TV stored services from an unintended transmitter;
- local interference affects some channels.

Information to Have Ready
Before requesting help, record:
- 1TV make and model;
- 2exact setup menu choices;
- 3number of services found;
- 4tested fly leads and outlets;
- 5old-TV comparison result;
- 6other affected televisions;
- 7exact missing channels;
- 8recent move, renovation, storm or equipment changes;
- 9property type and shared-system status.
Final work may be limited to the outlet or may involve the wider antenna path. The test results prevent a quote from assuming the wrong scope.

Verify the Setup After Channels Return
Once the television finds services, test several network groups rather than stopping at the first picture. Switch the TV off normally, restart it and confirm the channel list remains stored. Then check whether the electronic program guide and time information populate as expected.
If channels work only immediately after a scan and later disappear, record the timing instead of resetting again. That can indicate marginal reception, an unintended transmitter or a device problem rather than a simple initial setup error.
Keep the correct input and scan choices with the TV manual or household notes. A future software reset, move to another outlet or change of resident can then restore the tuner without altering the antenna system by guesswork.
10 / Questions
Frequently Asked Questions
Why does Netflix work but the TV finds no channels?
+
Netflix uses the internet. Free-to-air channels use the broadcast tuner and antenna connection, so one can work while the other fails.
Should I buy an amplified fly lead or booster?
+
No—not before proving a low-level clean signal is the issue. Extra gain can amplify interference or overload the tuner.
Does a smart TV need an antenna?
+
It needs an antenna signal to receive terrestrial free-to-air broadcasts. Streaming apps do not replace that physical path.
Can the wall outlet be inactive?
+
Yes. It may be disconnected, faulty or not part of the active distribution system. Compare another outlet and ask the property manager where relevant.
Why did the new TV find channels at the shop but not at home?
+
The shop and home use different signal sources and setups. Test the home outlet, tuner source and local antenna system.
