If your TV indicates there’s no signal but the cable box is turned on, this guide will show you how to fix TV Says No Signal But Cable Box is On this common problem. Hardware failure or severe weather are the most common causes of the ‘no-signal’ problem.
When there is snowfall, heavy rain, or strong winds, for example, service disruptions can occur, resulting in the message you are seeing on your screen.
Turn off your device and wait for any bad weather to pass before checking to see if the signal improves. The reason for this is that existing satellite equipment is set up to handle a particular level of severe weather, which produces interference.
However, if you’re certain there’s nothing wrong with the weather in your town/state and your TV hardware isn’t broken, the issue could be caused by something else that isn’t immediately apparent.
Procedure to Fix TV Says No Signal But Cable Box is On
You must follow the procedures given below to rule out any other potential problems with your TV connection in order to effectively troubleshoot the common NO SIGNAL network.
Issues with HDMI
Even though the cable box is turned on, if the HDMI port begins to shake, the consequence can be a ‘no signal’ error displayed on the screen.
Also, if the connectors are loose or slipping out, you may have a cable problem that necessitates replacement.
If your TV has an extra HDMI port, you can quickly swap it out by switching to the spare HDMI port. If your TV set does not have an extra HDMI port, simply unplug the HDMI cable and wait a few seconds before reinserting it.
This time, take your time and make sure it’s perfect. This should be sufficient to restore your TV signal.
Power off the TV and other Devices
One of the first things you should do is turn off your television and wait a few minutes before turning it back on.
If the problem persists, you will need to look into the ins and outs of each connection individually.
It’s not a tough procedure to follow. If you are using HDMI ports for anything else, simply unplug them before continuing.
- Look at the television.
- Box with a TV.
- Check to check if any of the cables are defective by wiggling them. If you have more cables to exchange and test, we recommend doing so.
Inspect your TV Box
When there is no signal error, it is most likely due to a problem with the setup box, either HD or SD. If the problem is with the box, turn it off, disconnect it from any connections, and wait for it to cool down.
In certain circumstances, a critical update may have been released that your box has yet to receive. As a result, when it is restarted, it will make the necessary adjustments and the signal strength will be increased.
It could be a matter of hardware failure in some situations, so if your TV box is not responding normally, is flashing repeated errors on startup, or fails to update, it’s crucial to contact your TV service provider’s customer service to address the issue and have a replacement box delivered to you.
Reset Television and Cable box
The significance of performing a device reset cannot be overstated. A restart operation simply does a soft reset, not a complete reversion.
A reset, on the other hand, will return all of the settings to default, with the exception of the user-mode settings.
When all previous alternatives have failed to correct your signal problem, the reset option is used. To effectively reset your cable box, follow these steps:-
- Turn off everything.
- Remove the power cord from the outlet. Then, for at least 5 minutes, be patient.
- After reconnecting everything, switch on the box.
In order to effectively reset the television:-
- Turn off the television.
- Remove the cord that is attached to the wall.
- Wait 5 minutes before turning it back on.
- Both techniques can be carried out simultaneously to see if they resolve the problem.
Restart Your TV
To thoroughly reset your TV and all connected equipment, follow these instructions:
- Turn off all of the lights on the wall.
- Wait 60 seconds after ensuring that all cables are correctly and securely in place before continuing.
- Please plug in your TV box (not the TV set) and wait another 60 seconds, or until the lights on the TV box stop flashing.
- Turn everything on and reconnect everything else.
Examine the Cable Box/Set-Top Box
Your set-top box could be the source of a no-signal issue in some cases. The provider may have issued new firmware and updated it in the background, regardless of whether you have an SD or HD box.
This means that fresh satellite settings have been uploaded, but the device hasn’t yet fully assimilated them.
Confirm if there is any Service Outage
If the problem persists, contact your cable provider to see if there is a signal loss in your region that is hurting your signal.
When it’s fixed, they will let you know. When there is a signal outage, there is little you can do but wait for it to be restored.
Select the Correct Input Source
Because of an improper input source, your TV may display a No Signal message. For your cable box and TV to work properly, you must select the appropriate input source. You have two options for selecting a suitable input source:

Step 1:
Turn on the television.
Step 2:
On the side or bottom of the TV, press the MENU button.
