If your Samsung Smart TV shows the “No Signal” screen every time you turn on the TV, you can change the startup behavior with a few simple settings. This is especially useful if you don't use a cable box, DTH box, set-top box, or any other external HDMI device.
In this guide, I will show you two simple methods to remove or change the Samsung TV No Signal screen. The first method is useful when you have a set-top box or another external device connected to the TV. The second method is useful when you don't use any set-top box or cable connection and want your Samsung TV to open Smart Hub instead of showing the default No Signal screen.
The exact menu names can be slightly different depending on your Samsung Smart TV model and software version, but the basic settings are similar.
Method 1: Select the Correct Input Source
If you are using a set-top box, DTH box, cable box, satellite receiver, streaming device, game console, or another external device, the first thing you should do is select the correct input source.
The No Signal screen usually appears when the TV is set to an HDMI or AV input that is not receiving a signal.
For example, if your set-top box is connected to HDMI 1, but the TV is currently set to HDMI 2, the TV may show the No Signal message.
To fix this, select the input that is actually connected to your external device.
Step 1: Open the Input Source
Press the Home button on your Samsung TV remote.
Go to Input Source or Connected Devices.
On some Samsung TV models, you may need to select Connected Devices from the Home screen and then select the input source.
Step 2: Select Your HDMI or AV Input
Find the HDMI or AV input connected to your set-top box.
For example, if your set-top box is connected to HDMI 1, select HDMI 1.
If it is connected to HDMI 2, select HDMI 2.
If you are using an older AV connection, select the appropriate AV input.
Step 3: Use Connection Guide if You Don't Know the Input
If you don't know which input your device is connected to, open Connection Guide.
Select the type of device you are using.
Follow the instructions shown on the TV to identify the correct HDMI or AV connection.
Once you find the correct input, select it.
Step 4: Leave the TV on the Correct Source
After selecting the correct HDMI or AV source, leave the TV on that input.
Now, when you use the TV with your set-top box or external device, you should no longer be stuck on an unused input that shows No Signal.
If your set-top box is turned off, however, the TV may still show No Signal because the HDMI input is not receiving a signal.
So make sure the external device is powered on when you want to use it.
What If You Don't Use a Set-Top Box?
If you don't use a set-top box, DTH box, cable connection, satellite receiver, or any external HDMI device, Method 1 may not be useful for you.
In this situation, there may be no active HDMI or AV source for the TV to display.
If your Samsung TV keeps showing the default No Signal screen when you turn it on, you can try the second method.
The idea is to make your Samsung TV automatically open Smart Hub when it starts.
Method 2: Turn On Autorun Smart Hub
Samsung Smart TVs have a setting called Autorun Smart Hub on supported models.
When this option is enabled, the TV can automatically open Smart Hub when you turn it on instead of simply starting on the previous input source.
This is particularly useful if you don't use a set-top box or cable connection.
Step 1: Open Settings
Press the Home button on your Samsung TV remote.
Select Settings.
Step 2: Open General
Inside Settings, select General.
Step 3: Open Smart Features
Select Smart Features.
Step 4: Turn On Autorun Smart Hub
Find Autorun Smart Hub.
Turn Autorun Smart Hub ON.
That's the main setting you need to change.
Step 5: Restart the TV
Turn off your Samsung Smart TV.
Wait a few seconds.
Turn the TV on again.
From the next time you restart or turn on the TV, the TV should automatically open Smart Hub instead of starting on an unused input that displays the default No Signal screen.
If You Cannot Find Autorun Smart Hub
Don't worry if your Samsung TV does not have an option called Autorun Smart Hub.
Samsung has changed its menu layout and setting names on newer TV models.
On some newer Samsung Smart TVs, the equivalent option may be available under the Start Screen Option settings.
Try the following path:
Settings → All Settings → General & Privacy → Start Screen Option
Look for an option such as Start with Smart Hub Home.
If you find this option, enable it.
Then turn off your TV and turn it on again.
Your Samsung TV should now start with Smart Hub instead of automatically displaying the previous input.
Which Method Should You Use?
The method you should use depends on how you use your Samsung Smart TV.
If you have a DTH or cable set-top box, use Method 1.
Go to Input Source or Connected Devices.
Select the HDMI or AV input connected to your set-top box.
If you don't use any set-top box or cable connection, use Method 2.
Go to Settings → General → Smart Features.
Turn on Autorun Smart Hub.
If your TV uses the newer menu layout, check Settings → All Settings → General & Privacy → Start Screen Option and enable Start with Smart Hub Home if available.
Why Does the Samsung TV Show No Signal?
The No Signal message normally appears when the TV is switched to an input that is not receiving a video signal.
For example, your TV may be set to HDMI 1 while nothing is connected to HDMI 1.
The TV then checks the HDMI input but cannot find a signal.
Instead of showing the Smart Hub or your apps, it displays the No Signal screen.
This can be annoying if you don't use external devices and simply want to use apps such as YouTube, Netflix, Prime Video, or other Smart TV apps.
Changing the startup behavior can make the TV more convenient to use.
Remove Samsung TV No Signal Screen When Turning On the TV
If your main goal is to remove the Samsung TV No Signal screen when you turn on the TV, first check whether you have an external device connected.
If you have a set-top box, select the correct HDMI or AV source.
If you don't have an external device, enable Autorun Smart Hub.
This changes the startup behavior so the TV can open the Smart Hub instead of remaining on an input with no signal.
If You Are Using a Set-Top Box
If you are using a set-top box, make sure both the TV and the set-top box are connected correctly.
Check the HDMI cable.
Make sure the HDMI cable is firmly connected to the set-top box.
Make sure the other end of the HDMI cable is connected to the correct HDMI port on the TV.
Select that same HDMI port from the TV's Input Source menu.
For example, if the cable is connected to HDMI 2, select HDMI 2 on the TV.
If you select HDMI 1 while your set-top box is connected to HDMI 2, the TV will show No Signal.
If you still see No Signal after selecting the correct input, check whether the set-top box is switched on.
You can also try another HDMI port if your TV has multiple HDMI connections.
If You Don't Use Cable or DTH
If you don't use cable, DTH, or any external set-top box, you may not need to use an HDMI input at all.
Your Samsung Smart TV can be used directly through its built-in Smart Hub and apps.
In this situation, enabling Autorun Smart Hub can be more convenient.
After enabling the setting, restart the TV and check what appears when the TV starts.
If your model supports the Smart Hub startup option, you should see the Smart Hub interface instead of the default No Signal screen.
Samsung TV Startup Screen Settings
The startup behavior can vary between Samsung Smart TV models.
Some older models may show Autorun Smart Hub under Smart Features.
Newer models may use Start Screen Option or a similar setting under General & Privacy.
Therefore, don't worry if your menu doesn't look exactly the same as the steps shown here.
The important setting to look for is the option that makes Smart Hub start automatically when the TV is turned on.
If the Setting Is Already Turned On
If Autorun Smart Hub is already ON but your TV still shows No Signal, check whether the TV is actually starting on the Smart Hub.
Turn the TV off completely.
Turn it on again.
Check whether Smart Hub appears.
If the TV still starts directly on an HDMI input, check the newer Start Screen Option menu if your model provides it.
You should also check whether the TV software has changed the location or name of the setting after an update.
Important Things to Remember
You don't need to change complicated picture or display settings to solve this problem.
First, identify whether you are using an external device.
If you use a set-top box, select the correct HDMI or AV input.
If you don't use a set-top box, try enabling the Smart Hub startup option.
The exact result can depend on your Samsung TV model, software version, region, and available Smart TV features.
Some Samsung TV models may not provide every Smart Hub startup option.
Final Solution
So, if you are looking for a way to remove the Samsung TV No Signal screen, there are two simple solutions.
For TVs With a Set-Top Box
Go to:
Home → Input Source / Connected Devices → Select the HDMI or AV input connected to your set-top box
If you don't know which input to select, open Connection Guide and check the connection.
For TVs Without a Set-Top Box
Go to:
Settings → General → Smart Features → Autorun Smart Hub → ON
Then restart your TV.
On newer models, check:
Settings → All Settings → General & Privacy → Start Screen Option → Start with Smart Hub Home
If this option is available, turn it on.
After making these changes, restart your Samsung Smart TV.
The next time you turn on the TV, it should start with the selected startup behavior rather than simply showing the default No Signal screen.
This is a simple way to change the No Signal screen when you turn on your Samsung TV, disable the default No Signal startup screen, and make Smart Hub open automatically when you don't use a cable or set-top box.
