Why is my HDMI not working on my Insignia TV

Short answer: Insignia TV HDMI not working could be caused due to multiple reasons which not only include a faulty Insignia TV itself but the Device whose screen is being shared and the HDMI cable. They could either be damaged or not set up properly, leading to HDMI not working.

Insignia TV HDMI not working

Reason 1- Improper connection

The first and foremost reason why the Insignia TV HDMI not working could be because of using the wrong port for connecting the device to the Insignia TV. Even though HDMI cables have a specific size and shape to help them fit, using the wrong port is often common.

Using the wrong port can additionally lead to damaged cable, and the used port itself. This means in the future if you tried using the same cable it has a chance of not working well or not working at all.

Reason 2- Incorrect Set-up

HDMI cables when plugged in help to display the screen/ content of the plugged-in device onto the Insignia TV. In the situation where you have plugged the cable properly but have not set it up well, the TV would fail to show any content.

There is a simple method to ensure that your TV is currently reading HDMI signals through the HDMI port, which we will discuss below.

Reason 3-  Faulty HDMI cable

One of the most common reasons. HDMI cables are usually not regularly used products, which means they are kept somewhere gathering dust, and sometimes even moisture resulting in damaged internal hardware. Rusting might also be visible in harsher conditions.

A damaged HDMI cable will fail to work at all and might result in the Insignia TV HDMI not working issue.

Reason 4- Damaged screen-sharing device

While rare, the output port for HDMI on your device may be damaged, or the device itself is damaged in some way that prevents it from sending the data to the HDMI or detecting the HDMI cable.

In either of these circumstances, you might not see physical damage, but you would be able to diagnose it only by using the proper tools. Do not worry, we have got a method to detect if your HDMI port is working flawlessly and awaiting connections from the cable.

Reason 5- Unsupported Feature

HDMI cables are great for video sharing along with audio, but not every Device has them. Older devices used to have VGA cables instead. The devices did not even have a port for HDMI at that time.

So if you are trying to use a device that does not support the HDMI feature either Software wise/hardware-wise or both, you would be unable to use it for screen sharing purposes.

Reason 6- Bad/ Incorrect configuration

Incorrect configuration is mostly an issue with the device that is sharing its screen rather than the one which is showing it.

This is not usually an issue as HDMI is flexible and auto adapts to different configurations, but if the device is older or unable to self-configure, you might need to configure it yourself.

Configuration issues are usually related to picture resolution, which is often different for the sharing device and the Insignia TV, leading to the Insignia TV HDMI not working.


Fix: Insignia TV HDMI Not Working (No Signal)

If you have read through the reasons we mentioned for why the Insignia TV HDMI not working, then you might have come to realize some of them require the simplest solutions. If you do not know, however, do not worry, we have got all the solutions for you here.

Method 1- Correcting the Video input

A basic but important step to make use of the HDMI cable is to use the right video Input. TVs usually have a selection of inputs to choose from. They generally include AV1, AV2, HDMI, and USB (if plugged in).

To use HDMI you have to change the video Input to HDMI. Simply look for the button labeled ‘Input’ or ‘Video’ or any video icon on the button. Pressing it multiple times would cycle it to other inputs. Leave it on HDMI input and you are set to use the cable!

Method 2- Using another HDMI cable

If you feel that the HDMI cable you are using is faulty or damaged in some way, the best option to test it is by using another HDMI cable (usually after trying it on another device and finding it to be working).

Use the appropriate ports to plug in the HDMI and check if the screen sharing works now. If it does, that means your previous HDMI cable was not working and needs to be replaced with a working one.

Method 3- Using the right port

HDMI can only be used in the right ports specifically made for them to be inserted. They resemble more or less a larger version of a micro USB port with small indents on both sides.

If you are having a hard time finding where the HDMI port is, a better idea is to look it up in the manual that was provided with your laptop or your device. You might even be able to find it by doing a little Google search online.

As for the Insignia TV, most of the ports would be available at a reachable depth at the back of the TV, directed side wards.

For most versions, they are usually on the left side, however, make sure to check your manual to confirm that it is the case with your model.

Method 4- Checking the Screen sharing device

Another potential issue could be a damaged screen-sharing device. For starters, it could be damaged hardware or a broken connection to the port. It could also be software-related issues and glitches.

The best option usually with these is to try rebooting it once, and see if the HDMI starts working. If you cannot find it to work, try troubleshooting a little based on when it was last working, and if any fall or damage occurred after that.

In all of these cases, your best bet would be to take the laptop/ PC/ amplifier/ device to its respective manufacturer’s customer service to have it repaired.

Method 5- Unplugging and Re plugging the device

We might have put this option a bit too late on for it to work, but the list is in no particular order and this method has so far proved to work more than others did, so here we are.

Doing this method is quite easy, all the user needs to do is unplug the HDMI cable from both the screen-sharing device and the Insignia TV.

Thereafter, plug it back again in the right ports. In case you find that the HDMI feature started working well after the re-plugging, it was probably a temporary glitch that got resolved.

Method 6- Checking screen sharing feature on the device

Screen Sharing/ mirroring has been around for quite some time. In older times this was done using VGA cables, that had a lot of pins. The downside of VGA cables was that they could not share the audio from the device, while an HDMI can.

Although in older models you might not find the software for HDMI at all (we are talking centuries old, back when the Intel Core duo was a thing).

Method 7- Contacting Insignia Customer service

If nothing worked for you, it is likely that the Insignia TV has an issue when it comes to HDMI, or perhaps even more. This is usually not the case, thus you should contact Insignia TV customer service.

After you get in touch with them, mention the issue, and they might tell you to do some troubleshooting. If it does not work, chances are you will get to have your TV repaired. Better still, if it is under warranty, it might even be replaced or repaired for free!

Here is a detailed list of all the contact numbers and emails from Insignia to help you get in touch: Insignia Customer service.
