Whether you use cable, satellite, internet TV, or an OTA antenna – you’ll discover targeted tips to resolve the frustrating “no channels available” message for good!

Verify Signal Connection and Strength

The first step is always to check your TV’s connections to the signal source – cable, satellite or antenna. Loose cables or faulty coaxial ports can cause intermittent signal issues leading to missing channels.

Carefully examine all physical connections to see if any cables are damaged or disconnected. Securely plug them into the correct ports on the TV and your set-top box/antenna. Faulty cables should be replaced for reliable signal transfer.

If your connections check out, verify if the signal strength is adequate – especially for over-the-air antenna channels. Navigate to the signal diagnostics menu on your Samsung TV to view real-time signal levels.

Antennas require strong signal strength for reliable channel detection. Consider repositioning the antenna or installing a signal amplifier if the levels seem low. Proximity to radio interference and physical obstructions can also impact OTA signals.

Intermittent signal loss causing the TV to freeze can also result in missing channels. See tips for troubleshooting Samsung TV freezing problems.

Perform Channel Scan

Once connections are ruled out, initiate a channel scan to re-tune your Samsung TV and update available channels.

You can find the auto-tuning or channel scan option under the Settings > Broadcasting menu. Newer models also include an Auto Channel Update feature that regularly scans for changes to broadcast lineups.

Channel scans systematically go through different frequencies to detect active stations. This can help restore missing channels that may have changed broadcast parameters.

For weak OTA signals, try the manual tuning mode in channel settings. This allows you to directly enter a channel’s frequency to manually force detection. Refer to official broadcast lineups for your area for specific channel frequencies.

Repeated scans may be required after making significant changes to connections, region settings or antenna upgrades.

Check for Software Updates

Like all smart devices, Samsung routinely rolls out firmware updates for its smart TV models. Installing latest updates is an important maintenance step.

Bug fixes, improvements and new features in updates can positively impact stability and channel detection capabilities. Failure to update periodically can actually result in channels going missing over time.

Navigate to Settings > Support > Software Update and select Update Now to check for and install pending system updates. If your TV is connected to the internet via Wi-Fi or Ethernet, updates will automatically download in the background once available.

Reset TV to Factory Settings

If you’ve made lots of custom changes and channels have suddenly vanished, consider reverting your Samsung TV to factory out-of-box conditions with a master reset.

Back up settings and data before resetting. Under General system settings, select the Self Diagnosis > Reset option. Confirm twice to erase all personal settings, installed apps, accounts and return to the default configuration.

Resetting gives the TV a clean slate eliminating any problematic customization that may be preventing proper channel tuning. Re-configure the basics like region, inputs, connections and scan for channels.

Problems like Samsung TV not turning on prevent accessing any channels altogether until power and connections are restored.

Contact Service Provider

Before getting into equipment troubleshooting, rule out any service issues by contacting your Pay TV or OTA broadcaster. Wider outages due to maintenance, upgrades and intermittent connectivity can stop channels from coming through.

Inquire if they are aware of any issues in your area and get updates on resolved before continuing equipment troubleshooting.

Switch Input Source

Accessing antenna/cable channels requires setting both the device input and TV tuner to the correct source. When using a set top box, make sure to change the input on your Samsung TV to match where this device is connected e.g HDMI-1.

If you have directly connected the coaxial cable from an off-air antenna or wall outlet, the input must be set to TV. When the wrong input is selected, the channels obviously won’t show up regardless of tuning attempts.

Change Region Setting

Geographical region settings automatically configure broadcast standards, frequencies and channel numbering conventions. Setting the wrong region can severely impact scanning and signal decoding – leading to missing channels.

If you have recently moved locations or even traveled abroad with your TV, ensure the region matches the Samsung TV’s current physical location for seamless channel detection.

Identify Source of Interference

Electrical devices like cordless phones, microwaves, baby monitors and WiFi routers operating in the 5GHz band can interfere with OTA TV signals and break channel reception.

If you consistently notice certain channels struggling even after scanning/tuning – identifying and keeping such devices away from your Samsung TV can resolve intermittent signal issues.

Upgrading to shielded HDMI/coaxial cables also helps eliminate electromagnetic interference effects.

Upgrade TV Antenna

Over-the-air channels require a strong antenna system for reliable reception without dropouts. Using older splitter-based antennas with amplifiers daisy chained to multiple TVs can degrade signals.

Upgrading to a newer amplified multi-directional antenna and directly connecting it to just the Samsung TV with the best reception can provide performance benefits.

Place antennas in a high, unobstructed location away from trees/buildings for optimal reception. Installing in the attic also offers protection from weather-related issues.

Issues with the TV randomly powering on by itself can disrupt your viewing experience and contribute to channels not being tuned correctly. Learn what causes Samsung TVs to turn on by themselves unexpectedly.


Q. Why does my Samsung TV not show all channels?

This is most commonly caused by loose antenna cable connections, obsolete TV software needing an update, incorrect input source selected or flaky over-the-air signal strength requiring antenna upgrades.

Q. How do I auto tune channels on my Samsung Smart TV?

Go to Settings > Broadcasting > Auto Tuning to start a channel scan. Ensure you have selected the correct input source before attempting to auto tune TV channels.

Q. What should I do when my Samsung TV says no signal during tuning?

Start troubleshooting by checking all physical connections, then contact your Pay TV/OTA provider to confirm if they have service issues. Retry tuning when issues are resolved on provider side.

Q. Can using the incorrect region setting make channels disappear?

Yes, region settings automatically configure critical broadcast standards and frequencies. The wrong region can absolutely cause channels not showing up during tuning.

Q. Why are antenna channels more prone to vanishing on my Samsung TV?

Over-the-air reception depends on antenna type, placement, cabling, amplifiers and environmental factors. Intermittent signals can lead to missing channels. Upgrade your OTA equipment for reliable reception.

Q. How often should I rescan channels on my Samsung Smart TV?

Samsung recommends periodic channel scans to continue detecting newly launched stations as they come online. Broadcast lineups evolve so it’s best practice to rescan every few months.


Struggling with some missing channels on your new Samsung Smart TV? Don’t panic and assume its a complex hardware flaw right away. In most cases, the “no channels found” error can be easily fixed using simple troubleshooting techniques.

Carefully going over your connections, cables, input settings, antenna upgrades and firmware updates can get your full programming lineup back up in no time. Pay attention to the exact error messages and cues during failed tuning attempts to zero in on the potential issue.

Stay calm, be patient and methodically try the step-by-step corrective measures outlined in this guide. Have all your settings configured correctly before attempting channel scans.
