Why Does My Samsung TV Say Weak or No Signal?

I recently encountered a frustrating issue with my Samsung TV. After connecting my cable box, I encountered an error message saying “Weak or No Signal”. I was baffled as to why this was happening, as my cable box was working properly and the TV was connected to the right source. I decided to do some research to see what might be causing the issue and what I could do to fix it.

In this blog post, I’ll share what I learned and the solutions I tried that ultimately worked. Hopefully, I can help other Samsung TV owners who may be facing the same issue.


  • Check the TV Input connections to make sure they are secure.
  • Reset the TV box and wait at least a minute before reconnecting it.
  • Inspect your aerial system and install it at the highest point possible.
  • Replace any faulty cables or TV receivers.
  • Try a soft reset of the TV and check for pending updates in the Support menu.
  • Consider getting a higher-gain TV aerial if the signal is weak.
  • In the worst-case scenario, replacing the TV box or the aerial may be necessary.

Why Does My Samsung TV Say Weak or No Signal?

You’ll know for sure that your problem is a weak signal if the picture displayed is distorted or unclear. In case you’re only getting audio and no picture, then you also have a weak TV signal.

The same applies when your screen shows a ‘No Signal’ message.

That said, a weak signal can be due to a number of factors. Below, we cover the most common reasons for transmission issues.

Check the TV Input

Often the case is simply a bad cable connection that’s messing up with your picture display. The TV box needs to be properly linked to your TV screen otherwise, it won’t show the channels clearly.

Make sure that you check that the cable is secure, and if it’s not, try setting up the TV box again.

In case you still don’t get a clear picture, consider replacing your cable or the TV receiver, since there might be a problem with the wires. If all else fails, try connecting the cable to a different input source. Make sure that any HDMI cables are connected correctly.

Also, it might be the case that you have not got the correct input source selected on your TV.

Reset the TV Box

Sometimes it’s not the cables, but the TV box that’s the problem. This is most probably the cause, especially if the TV box has been acting up for a while now.

Look for prior signs, such as the box being unresponsive to the remote control. If you’ve been experiencing multiple lagging issues, then you should try resetting the TV box.

Here’s how you can quickly do that:

  1. Turn the TV box off
  2. Disconnect the device from its cable source
  3. Wait at least a minute before you reconnect it
  4. Let the TV box finish rebooting for two minutes
  5. Turn the appliance back on
  6. Test to see if the signal has been restored

Inspect Your Aerial System

Did you know that many factors could mess up your aerial signal? For instance, if you live in an area with a weak signal, this will most likely distort the TV’s picture display.

Additionally, construction sites and nearby obstructions can also affect how strong the signal you get is. 

The best way to avoid such problems is to install your aerial at the highest point possible. Favoring an outside aerial system for an indoor one will work wonders as well.

In the event that none of the above pose an issue for you, then the cause of your weak signal may lie in the type of aerial system you have installed. In other words, you might want to get a higher-gain TV aerial.

These kinds of aerials are pretty effective in improving the signal’s overall performance. Plus, if you have multiple TVs connected to the same aerial, you may need one that’s able to provide you with an optimal viewing experience across all devices.

Reset the TV

Restarting your Samsung TV might help fix the problem, and any other malfunctions you might have been experiencing as well.

Often, a soft reset is all that is needed to solve issues on a Samsung TV. A soft reset does not erase any data. To soft reset a Samsung TV, you simply need to turn the TV off, then remove the plug from the wall outlet and wait for 60 seconds, then put the plug back in and turn the TV on again

Properly reconnect your cables before attempting to turn your TV back on. The screen should show you that the device is rebooting. 

Once that’s done, your signal issue should be resolved.

Try a hard reset

A hard reset involves completely reseting the TV to its factory defaults and your data will be erased.

To do this, do the following:

  1. Turn on the TV and press the “Home” button on the remote
  2. Go to “settings”
  3. Then click “general”
  4. Then click “reset”
  5. You must then enter a 4 digit pin number which is 0 0 0 0 by default
  6. Then click ”Yes” to reset the TV
  7. The TV will then turn off once it has finished resetting
  8. You can now turn the TV back on and set it up again

Update the Software

Postponing important updates causes your device to be rigged with bugs, which in turn, leads to signal problems and more often, audio issues as well.

A quick fix you should start with is checking for any pending updates in the Support section of your General Settings.

You can turn on automatic software updates by going ”settings” then ”support” then “software update” and ensure ”Auto Update” is turned on. Alternatively, you can manually update over the internet by clicking ”Update now”

To Sum Up

Wondering why does my Samsung TV say weak or no signal? No worries, our guide today has helped you identify the possible causes for this issue and how you can successfully resolve them. 

A safe place to start is with your TV box. Try replugging or rebooting the device for a few seconds and hooking it up again. Another good idea would be to check your aerial installation system and make sure that its set-up is optimal.

Worst case scenario, you might need to replace the TV box or the aerial. Other than that, you should be able to enjoy your favorite shows in no time!
