One of the most common reasons for the No Signal message is a loose or damaged cable connection.
This can happen if the cable you’re using for connecting your TV to the order devices becomes unplugged or jostled.
In some cases, the problem could be with your TV itself. Whatever the reason may be, fixing this is quite important before you can get to use your Insignia TV with the device again.
In this post, I have put together some likely causes of the no signal error you’re experiencing on your Insignia TV. Rest assured, fixing this issue isn’t difficult at all.
I’ve included easy to adapt solutions and proven troubleshooting steps to guide you through the process. So, let’s proceed and get your TV signal back up and running in no time.
No Signal Detected Error: What Does It Mean
Apparently, the no signal detected error message on your Insignia TV indicates that the TV is not receiving a signal from the external device attached to it. Whether it’s receiving an unrecognized signal or no at all.
This message usually appears when the TV is set to a particular input source, but there is no active signal coming through that input.
This particular error can occur due to various reasons, including connection issues, incorrect input selection, or problems with the source device.
Possible Causes of Insignia TV No Signal Detected Error
Knowing the cause of an issue is often the most unanswered question for users struggling with their electronics.
Am sure you also must have been wondering what can actually cause the no signal detected message on your Insignia TV.
Here are some possible causes of the issue:
Loose or Faulty Connections
One of the most common causes of the no signal error message on TVs is loose connections. If the HDMI or other cables connecting the TV and the source device are loose, damaged, or not properly connected, your TV may not receive the signal in an appropriate way.
This tends to happen maybe when you connect both devices without cross checking whether it’s firmly plugged into the TV or not. That is, when you’re in a hurry.
And also, the cable can become loose over time, causing the signal to get lost even when a shake happens either to your Insignia TV or the source device you’re connecting with.
Incorrect Input Selection
Sometimes, the no signal message can appear on your Insignia TV if you accidentally change the input.
This can happen when you mistakenly press the input button on your Insignia TV remote or you’re unsure about which input port the source device is connected to.
If the TV is set to an input source that is not actively transmitting a signal, such as an unused HDMI port or a disconnected cable box, the no signal detected message will likely appear on your screen to let you know the TV is not currently receiving any signal.
Faulty Hdmi Cable or Bad TV Input
Another possible cause of the Insignia TV no signal detected error is faulty HDMI cable and input issues. A faulty HDMI cable can probably disrupt the transmission of audio and video signals between the source device and your TV.
This can result in a loss of signal and the appearance of the no signal detected message on your screen.
On the other hand, when the HDMI input of your TV is acting up due to the device age or other reasons, this can also bring about the no signal message that you’re staring at.
In such instances, try using a different HDMI cable. Ensure that you have the correct input selected on your TV. And also, try rebooting both devices by unplugging it from the power source for a few minutes, then plugging it back in.

Source Device Issues
The source device itself may be experiencing problems, such as being powered off, not connected properly, or malfunctioning which probably needs a restart.
In case you’re trying to establish a connection with a streaming device there are chances that device output can’t be read by your Insignia TV.
This can probably be caused by incorrect settings on the source device, such as a wrong output resolution or incompatible video format.
As your TV can’t define the signal, the no signal prompt will likely be triggered and come up on your TV screen.
Moreover, running an outdated software on any of the devices can relatively cause compatibility issues and result in no signal detected error.
Firmware or Software Glitches
In some cases, outdated firmware on the TV or software issues within the source device can result in signal detection problems.
Since manufacturers always ensure to keep their products up-to-date with timely releases of software and firmware updates,
installing these on your devices shouldn’t be overlooked as it can save you a great amount of time that you might later need to fix an error.
Knowing these causes is quite important. You will get to know the dos and don’ts that might actually prevent a future occurrence of such a problem.

How to Fix Insignia TV No Signal Detected Error
Check for Server Downtime
Formost, check if there is a server downtime in your area or geographical location.
This tends to be relevant if your having issues connecting a digital player with your Insignia TV. Whether it’s an android box or streaming stick.
Sometimes, the problem may not lie within your Insignia TV but with the service provided by the manufacturers of your streaming device.
Before trying out any other potential solution for fixing the no signal detected message on your Insignia TV,
checking whether the problem is only applicable to your device or not is quite important.

After finding out you’re the only one experiencing the no signal detected error, now check if you are selecting the right input mode on your Insignia TV.
Actually, it’s quite essential to verify that you’re choosing the correct input source on your TV, especially if you have multiple devices connected to it.
Here are a few things you can do to ensure you’re selecting the right input mode on your Insignia TV:
1. Check the labels: If you’re not sure which input to choose as you have forgotten which of the available HDMI you have the device plugged into,
you can get closer to the TV and access it back to check the labels on the input in order to identify the specific one you will be choosing.
This issue tends to happen often if your Insignia has more than one HDMI input port.
2. Use the remote: Use the TV remote control to select the input. If you’ve lost your remote, you can purchase a replacement from Insignia or use a universal remote that’s compatible with your TV.
Using a model that comes with either Fire or Roku built-in, you can download it mobile App and use the controller function.
Using the TV remote, press the Input or Source button to access the input menu on your Insignia TV.
Scroll through the available input sources (HDMI 1, HDMI 2, or 3) and make sure the correct source is selected for the device you are trying to use.
This is applicable to any type of input port you’re having issues with whether it’s composite, component, or VGA.
However, you can only try a different HDMI port, especially if your TV possesses more than more since a particular HDMI port can be faulty sometimes.
Quick Reboot Both Devices
Power cycling often free electronic devices from glitches or malfunction caused by over worked system, when the devices have been turned on for an extended period of time.
If your Insignia TV is still displaying a no signal message after ensuring you’re selecting the correct input mode, you may need to perform a quick reboot of both your TV and the connected device to fix the issue.
This process is pretty simple and can resolve any issue beyond the no signal detected message you’re experiencing on your Insignia TV.
To do a quick reboot for your Insignia TV and the connected device, follow these step-by-step procedure:
- Grab your TV remote and turn off your Insignia TV
- Get closer to it and unplug it from the power source.

If the issue persists after the quick reboot, you may need to try some other troubleshooting steps.
There are few more things to check out below such as checking the HDMI cable or port.
Tweak the Resolution of Connected Device
This particular fix is quite helpful when the issue arises because of unsupported video format that is being transmitted from the source device you have connected with your Insignia TV.
When you deliberately tune the resolution of the device to some extent that is incompatible with your TV, the no signal detected or unsupported mode screen may likely come up on your TV screen.
In such instances, fixing this is a straightforward concept, all you have to do is to find a means to tweak the resolution and output format of the connected device.
Try accessing the device on another TV and if it works perfectly, then the issue is either with the resolution or your TV input port.
To fix the resolution issue, take some moment to tweak the resolution of the source device. Here are some steps to follow:
- If possible, access the device on another TV – If it works well, then proceed with these steps.
- Go to the settings of the connected device and look for the display or resolution settings.
- Select the minimum or average resolution that is compatible with your Insignia TV.
- You can always refer to the TV manual or the manufacturer’s website for the recommended resolution for your device.
- In such instances when the recommended resolution is not available, try selecting a lower resolution.
- Now reconnect the source device with your Insignia TV to see if it’ll work.
- If the lower resolution works, you can try increasing the resolution gradually until you find the optimal setting.
Keep in mind that not all devices have the same display settings, so the steps may vary depending on the device you’re using.
If you’re unsure how to adjust the resolution, you can refer to the device manual or contact the manufacturer for assistance.
In addition to adjusting the resolution, you can also try changing the refresh rate of the connected device.
A higher refresh rate may improve the picture quality, but it may also cause compatibility issues with the TV.
It’s recommended to try out different refresh rates to find the optimal setting that works well on your Insignia TV.
Check the HDMI Port on the TV
Since tweaking the device resolution doesn’t help in fixing the issue, check out and examine the HDMI port on your Insignia TV.
The input port may be acting bad if it’s damaged or blocked with dust and some other substances.
To begin with, get closer to your TV and check for any physical damage.
Inspect the HDMI port on the TV to make sure it’s not damaged or obstructed in any way. If there is any debris inside the port, gently clean the port before attempting to connect an HDMI cable.
In case you noticed a damaged port as some pins from the ports can’t be found or already wear down, you will need to have the port fixed before you can be able to use it again.
If it warranty period is still valid, you can contact Insignia support to sort things as they can provide you an expert to fix it for you.
And also if your TV have more than one HDMI Input port, try switching to another if it will work.
Check for a Damaged HDMI Cable
In some instances, a damaged HDMI cable could be the culprit. It is advisable to inspect the cables for any signs of damage, such as frayed wires or bent connectors.
Here’s what you can do to check if your HDMI cable is damaged:
Inspect the cable visually. Check for any visible signs of damage such as frayed wires, bent connectors, or any other physical damage. If you see any damage, replace the cable and try things out.
Swap the cable. If you don’t see any visible damage, try swapping the HDMI cable with another one. This doesn’t requires buying a new one before being certain that’s the cause.
If you another devices being connected with HDMI cable, you can try using the cable to test out your Insignia TV with the source device. This will help you determine if the cable is the problem or if it’s something else.
Additionally, check the connection between both devices. Make sure that the HDMI cable is properly connected to both your TV and the device you are trying to connect. Ensure that the connectors are firmly in place.
Disconnect and Reconnect the HDMI Connection
The thing you should try out here is disconnecting and reconnecting the HDMI connection. This is a common solution that can fix the issue in many cases.
To disconnect the HDMI connection, follow these steps:
- Turn off your TV and any devices connected to it, such as a cable box, digital media player or gaming console.
- Locate the HDMI cable that connects the device to your Insignia TV.
