HDMI Not Working on Roku TV

HDMI connections can be delicate with any TV. The connection point may not be secure, or the cord may have been damaged in some way, along with a variety of other issues. Let’s look at some of the reasons why HDMI may not be working on your Roku TV.


If HDMI isn’t working on your Roku TV, it could be because the connection is loose and not staying connected. It is also possible that the cord may be broken or the TV isn’t set to the correct HDMI signal.

The good news is that these are relatively easy to test and fix. Let’s look at these problems, and then we’ll talk about how you can go about fixing them. 

Why HDMI Isn’t Working on Your Roku TV

Roku TV why HDMI

As I mentioned, there are specific reasons why your HDMI isn’t working on your Roku TV, and most are relatively simple. On rare occasions, you may experience other issues that aren’t related to these, but this hardly ever happens, and when it does, it’s usually a combination of other problems.

  • The connection coming loose is standard in older TVs. Over time the connection ports simply become loose from extended use, which can result in issues with the Roku TV showing whatever you’re attempting to play via HDMI. 
  • The cords also develop wear and tear over time. This is more common when used for a while, but damage can happen when being moved or bent incorrectly.
  • The final reason your HDMI may be having issues is less to do with the connection and more to do with the TV. Roku TVs, like other TVs, come with multiple HDMI channels. The connection must match the signal on the TV. Otherwise, the HDMI will appear not to be working. 

Let’s look at each of these in a little more detail. 

The Connection Port Is Loose

As we discussed, this is common, particularly if your TV is older. Over time the ports loosen with being moved or with HDMI cords inserted repeatedly into the port.

There’s nothing you can do about this other than get it replaced by a professional or replace the TV. 

You may not initially notice that the port is loose. Usually, they don’t show signs that the HDMI doesn’t work in that specific port. You can usually test this by plugging the device into multiple ports and see if this corrects the problem. If it does, you’ll know that the port is the problem. 

The HDMI Cord Is Bad

HDMI cords can go bad, and it can happen for about any reason. Usually, the cord gets damaged in a moving process or something similar. It can also be damaged if the TV gets sat on top, which happens more often than one would imagine. 

Occasionally when you order HDMI cords online, they don’t work from the time that they arrive. Depending on the cord manufacturer, they are sometimes poorly made, and while frustrating, this is a fact of life. 

The best way to test the HDMI cord is to connect it to a different TV and see if it works on this device. If the cord is bad, you may notice that you have no connection at all, or you may have a connection that goes in and out. 

The Roku TV Isn’t Set to the Right Signal

There are multiple HDMI signal options on your Roku TV. This is dependent on how many HDMI ports your specific TV has, but most of them have either three or four

If you notice that everything else seems to be in order, but the HDMI still isn’t working, it’s most likely due to an error by the user rather than a problem with the devices. Try switching between multiple HDMI signals on your TV, pausing at each one. 

If this is the problem, it will pick up on one of the signals as you flip through. 

How To Fix HDMI Not Working on Roku TV

Now that we’ve discussed the problems you may encounter, let’s discuss some possible solutions. Most of the solutions we’ll discuss today involve simply testing your HDMI cord and ports and replacing them as necessary. 

While you can take additional steps, such as bending your cord in specific ways or something similar, it simply works best to replace the problem area.

Let’s jump into solutions now!

Test Your HDMI Ports

As we discussed, bad HDMI ports are some of the most common issues you’ll encounter if the HDMI appears not to be working. 

The best way to test your HDMI ports is to plug the HDMI cord into various ports and switch the TV signals appropriately. 

Cycle through each one, pausing at each signal until the TV has time to catch up. 

You should test the HDMI ports with something besides the initial device you were trying to use. For example, you may want to plug in a different laptop to ensure it’s an issue with the TV’s HDMI ports rather than the device you were attempting to connect. 

If you find the port is wrong, you’ll need to move your HDMI cord to another port. You can have the port replaced by a professional if necessary.

Test and Replace the HDMI Cable

The HDMI cable is more frequently the problem than the ports. This is partly because cords are often cheaply made, particularly if you’re not buying at least an HDMI 2.0 cable built to run at high speed. 

The best way to test the cord is to plug it into a different port or a different device. Usually, a different device is better than a different port because the two are somewhat interconnected.

If you find that the cable isn’t working, no matter where you plug it in, then it’s time to replace your cable. Normally, you get a fairly good quality one for less than $30.00.

Cycle Through Your Roku TV’s HDMI Signal Channels

If the problem ends up being that you are on the wrong HDMI signal on your TV, then your screen isn’t going to show anything or play any audio. You’ll see a black screen. 

The easiest way to cycle through your Roku TV’s HDMI signal channels is to push the input button multiple times, pausing each. The screen may initially be black and jump to the picture within a few seconds. 

This process shouldn’t take more than a couple of minutes. If you’ve already cycled through a couple of times and can’t get a solid picture, then more than likely, this isn’t the problem. 

Final Thoughts

When the HDMI isn’t on your Roku TV, it’s almost a problem with the port or the cord. On rarer occasions, it’s due to a user issue where the Roku’s HDMI signal isn’t corresponding with the appropriate port.
