No Signal on Your TV? Simple Troubleshooting Tips That Work
Few things are more annoying than switching on the TV and seeing No Signal on your TV instead of your favourite channel. This message does not always mean something is broken for good. In many cases, the cause is a loose cable, a wrong input, or a tuning issue. Still, it can also point to antenna or signal faults that need proper attention.
Brocky’s TV is a local Sunshine Coast business that handles TV antenna repair, digital TV reception, TV installations, and electronics repairs. Before calling for help, try the steps below. They are written for everyday homeowners and cover the most common causes.
Step 1: Check the TV input source
Modern TVs have several inputs: HDMI, AV, and TV (antenna). If the TV is set to the wrong source, it will display a ‘no signal’ message even when everything is connected.
- Use the TV remote and press Input or Source
- Select TV, DTV, or Antenna if you watch free-to-air channels
- If you use a set-top box, select the HDMI port it is plugged into
This simple step fixes a large number of “no picture” calls.
Step 2: Inspect all cables and connections
Loose or damaged cables are a top cause of No Signal on Your TV. Check:
- The antenna cable is firmly plugged into the back of the TV or set-top box
- The wall socket is not loose
- There are no sharp bends or crushed sections in the cable
- Any splitters or joiners are tight and not rusted
If you see green marks, rust, or broken ends, the cable may need to be replaced.
Step 3: Power cycle your TV and equipment
Sometimes the TV or connected box just needs a fresh start.
- Turn off the TV and any set-top box
- Unplug them from the power for 30 seconds
- Plug them back in and turn them on again
This can clear small software glitches that block the signal.
Step 4: Retune your TV channels
Digital TVs need correct tuning to lock onto broadcast frequencies. If channels are lost after a storm or power cut, retuning often restores them.
- Go to the TV menu
- Find Channel Setup or Auto Tune
- Run the scan and wait for it to finish
If the scan finds no channels at all, the problem is likely in the antenna system rather than the TV.
Step 5: Look outside at the antenna (if safe)
If you can see your roof antenna from the ground, check for:
- Antenna pointing in a different direction than before
- Bent or broken elements
- A mount that looks loose after strong winds
Do not climb onto the roof unless you have proper safety gear. A moved or damaged antenna is a common reason for No Signal on Your TV, especially after bad weather.
Step 6: Think about recent changes
Ask yourself:
- Did you move the TV or furniture?
- Did you add another TV and split the signal?
- Did any building work happen near your home?
Extra splits, longer cable runs, or new obstacles can lower signal strength enough to cause dropouts or total loss.
When simple checks are not enough
If you have tried the steps above and still see no channels, the fault may be in the antenna, cabling inside the walls, or signal levels at your location. Older antennas may not suit current digital broadcasts. Water can also seep into cables over time, blocking the signal.

For homes with wall-mounted TVs, poor cable runs or tight bends behind the screen can also cause trouble. This article on safe TV wall mounting and cable setup covers what to watch for.
If your viewing relies on both streaming and free-to-air channels, a weak internet connection can add to the confusion. This post on home WiFi setup for stable streaming shows how signal quality affects smart TVs.
Why local signal conditions matter
The Sunshine Coast has a mix of coastal weather, hills, and new buildings. Two houses on the same street can get different results from the same antenna type. That is why a local service checks signal levels at your roof and at the TV point, not just the TV screen. A proper fix targets the cause, not only the message on the screen.
What a professional visit usually covers
A service call for No Signal on Your TV often includes:
- Testing signal strength and quality
- Checking the antenna direction and condition
- Inspecting cables, wall plates, and splitters
- Replacing failed parts if needed
- Manually tuning channels for stable results
This approach avoids repeated issues and saves time in the long run.
A simple rule of thumb
If the problem started after moving the TV, changing cables, or a power cut, it is likely a setup or tuning issue. If it follows a storm, shows up on all TVs in the house, or keeps coming back, the antenna system probably needs work.

FAQs
1) Why does my TV say “No Signal” but my cables look fine?
The TV may be on the wrong input, channels may need retuning, or the antenna signal may be too weak to lock onto.
2) Will retuning always fix the problem?
Retuning helps when channels are lost, but it will not fix damaged cables or a faulty antenna.
3) Can bad weather cause total signal loss?
Yes. Strong wind can move an antenna, and rain can get into old cables, both of which can block the signal.
4) Does adding another TV affect signal strength?
Yes. Each split lowers the signal level. If the system was not built for extra points, dropouts or no signal can happen.
5) When should I call a professional?
If checks and retuning do not resolve the issue, or it keeps returning, a technician can test the system and identify the cause.
