If your TV says no signal but the cable box is on then you are not alone, this 2024 guide will help you find a solution for this common simple fix. The main reason for the โno-signalโ issue to occur is the result of hardware failure or bad weather.
For instance, when there is snowfall, heavy rain, winds then it can cause service outages that can display the message you are seeing on your screen.
At this point, you need to turn off your device and wait for any bad weather to blow over and see if the signal improves. The reason is that current satellite devices are configured to cope with a certain rating of severe weather conditions that causes interference.
But, in a situation where youโre sure there is nothing wrong with the weather in your town/state and your TV hardware is not failing, it means the problem might be linked to something else that may not seem obvious at first.
The โNo Signalโ Explained
The majority of TV manufacturers have an automatic connection apparatus that allows devices to be spotted and showcased on the screen when the remote is turned on.
When your TV says no signal even when itโs linked to the correct input or source, at that point, it means youโre faced with network issues.
How to fix it?
To effectively troubleshoot it the common NO SIGNAL network is as follows, you need to follow the steps outlined below to rule out any other potential problems with your TV connection.
1. Power off the TV and other devices
One of the first things to do is power off your TV, then wait for a few minutes before restarting it. If the problem continues, then you need to check the inโs and outs of the connections individually. Itโs not a difficult process. If you make use of HDMI ports for whatever purpose, simply remove them before you continue
- Check the TV
- Cable Box
- Try wiggling the cable to see if each cable is faulty. We recommend if you have other cables to swap and test then we recommend doing so.
2. Inspect your TV box
Most times when no signal error occurs, it might originate from the setup box either HD or SD. When the problem is related to the box, you need to switch it off, remove it from every connection, then be patient and wait for when it cools.
In some cases, there might be an important update that your box is yet to integrate. Hence, the process of restarting it will do the necessary adjustment and the signal strength will be boosted.
In some cases, it could be a case of hardware failure so if your TV box is not responding normally or is displaying multiple errors on start or fails to update then its important to talk to your TV service provider customer support to address the issue for a replacement box to be sent out to you.
3. Issues with HDMI
At any point when the HDMI port starts to shake, the result can be a โno signalโ error displayed on the scene, even when the cable box is โONโ. Also, when the connections are not properly fitting or slipping out then you have a potential cable issue that may need replacing.
For TV sets that come with additional HDMI, you can easily swap it by changing to the spare HDMI ports. But in a situation, where your TV set lacks an extra HDMI port, just remove the HDMI cable, wait for a few seconds before reinserting it again. This time, be deliberate and make sure itโs tight. This should be able to fix your TV signal.
If you are still having issues with the HDMI port then try connecting another device (with HDMI) with the same cable and port to see if you TV hardware has not failed.
4. Confirm if there is any service outage
If it continues, you can reach out to your cable provider and inquire if there is an outage with your area that is affecting your signal. Theyโll let you know when it will be fixed.
Once there is an outage, there is nothing you can do other than to be patient, and wait for when the signal is restored.
5. Errors related to HDCP
HDCP errors can sometimes affect your TV set. This is an anti-piracy approach that recommends that non-licensed devices shouldnโt be permitted to receive any cable TV content. All modern Television sets are HDCP-compliant.
6. Reset Television and Cable box
The importance of device reset cannot be overemphasized. A restart procedure only makes a soft reset and wonโt revert everything.
But a reset will alter the entire settings apart from those which is a user-mode to the default. The reset option comes to play when all other options did not rectify your signal error.
To effectively reset your cable box;
- Switch everything off.
- Remove the power cord connected to the wall. Then be patient for at least 5 minutes.
- You can reconnect everything, the turn the Box ON.
To effectively reset the TV;
- Switch off the TV

Both procedures can be done at the same time to see if they will rectify the issue.
