No Signal
Hisense No Signal on Smart TV: no aerial or input signal
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
On a Hisense VIDAA Smart TV, No Signal means the selected input is not receiving a signal: a loose or misconnected aerial, the wrong source or an external device that is off. Check the cable and source, run the Input Connection Test and scan channels again.
Safety first
Stop and check this first
- Do not open the TV over a missing signal: there are dangerous voltages inside even when unplugged, and the cause is usually the aerial or connection.
- A factory reset erases your settings, information and personal data; Hisense suggests restarting the TV first, which does not erase anything.
Safe checks you can perform
- Check the aerial cable
- Select the correct input source
- Run the Input Connection Test
- Restart the TV and scan channels again

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Aerial check by an installer
What they doIf there is still no signal or a weak signal in Live TV with the cable properly connected and after a new scan, an aerial installer checks the antenna, its direction and the cabling.
They must show youthe signal reading at the TV's wall socket.
In writingwhat was adjusted or replaced and the final signal level.
Contact the set top box provider
What they doIf the missing signal only happens with the set top box and the input is correct, its provider checks the box's signal or network.
They must show youthe signal or network status of the set top box.
In writingthe ticket number and the fix applied.
Hisense authorised service
What they doIf no input receives a signal with devices and cables that work on another TV, Hisense authorised service checks the TV.
They must show youthe diagnosis on the affected inputs.
In writingthe repair done, any part replaced and the warranty applied.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Check the aerial cable
- Who:
- you, no tools needed.
- How:
- make sure the antenna cable and connector are not damaged, loose or disconnected and that the cable is in the correct port on the TV. If no signal or weak signal happens only occasionally, disconnect the antenna cable and reconnect it, as Hisense advises.
- Result that matters:
- ruling out a faulty aerial connection.
- If the picture returns:
- it was the cable or connector.
- If there is still no signal:
- check the input source.
- Evidence to keep:
- a photo of the aerial connector on the TV.

Select the correct input source
- Who:
- you, with the remote.
- How:
- for the aerial, choose TV as the input source. For an external device, choose the exact input it is connected to: if the cable goes to HDMI1, select HDMI1. Also check the device is on and the connection is secure.
- Result that matters:
- the TV showing the input where the signal arrives.
- If the picture appears:
- the source was different.
- If the source is right and there is no signal:
- run the Input Connection Test.
- Evidence to keep:
- a note of the source and port used.

Run the Input Connection Test
- Who:
- you, with the remote.
- How:
- go to Settings > Support > Self Diagnosis > Input Connection Test, pick the source and check the information about the external connection. Settings > Support > System Info also shows Signal Info for the current input; menus may differ by model.
- Result that matters:
- seeing whether the TV detects the connection and with what signal.
- If the signal is weak:
- check the aerial or the set top box.
- If nothing is detected on any input:
- restart the TV and scan channels again.
- Evidence to keep:
- a photo of the test screen or Signal Info.

Restart the TV and scan channels again
- Who:
- you, with the remote.
- How:
- turn the TV off, unplug the power cord from the outlet and plug it back in after 60 seconds; Hisense says a restart does not erase your settings. If the problem remains in Live TV, go to Settings > Channel > Auto Channel Scan and let the scan finish.
- Result that matters:
- ruling out a temporary glitch or an old channel list.
- If the channels return:
- it was the tuning or a temporary glitch.
- If still no signal with the aerial properly connected:
- call an aerial installer.
- Evidence to keep:
- the number of channels found and the time of the scan.

What it means
Hisense VIDAA manuals treat no signal or a weak signal in Live TV and from external devices as a connection or reception problem. They ask you to check the aerial cable is not damaged, loose or in the wrong port, that the correct input source is selected and, with a set top box, its signal. The TV includes an Input Connection Test and a Signal Info screen to check this. If it happens only occasionally, reconnecting the cable is enough. The code alone never proves the TV has a faulty part.

Symptoms and causes
Probable causes · in order
- Aerial cable loose, damaged or in the wrong portCommon
The Hisense manual asks you to make sure the antenna cable is connected to the correct port and is not loose, disconnected or damaged.
Evidence: Hisense 55A6GV user manual (VIDAA E-Manual 9602 U5 NA) · Hisense: manual electrónico MT9603 VIDAA U7.6 NA/SA
- Wrong input sourceCommon
Hisense says the right input source must be selected: TV for the aerial, or the exact input of the device, for example HDMI1 if the cable goes to the HDMI1 port.

- Set top box or external device with no signalPossible
With an external set top box, the manual suggests unplugging and replugging its cable and checking its signal, because the TV only shows what the box sends.

- Outdated channel listPossible
If the connection is fine and the problem persists, Hisense suggests scanning channels again, which points to an old or incomplete tuning.
