Roku TV HDMI No Signal? Try These 14 Fixes

Roku TV HDMI No Signal

As helpful as it is, technology can also be pretty unreliable in some situations, such as getting your Roku TV or TCL Roku TV to pick up its signal. Essentially, your TV displaying No Signal means it should be receiving audiovisual data from somewhere, but nothing’s coming through

Hence, you get an alert that its ports are not picking up any signal (NO SIGNAL) from your intended source – your PlayStation, Roku streaming device, or others.

The most logical way to fix this is by ensuring the ports are well connected, but sometimes the error might not originate from the connection ports. Don’t freak though; we’ll discuss possible solutions to fix all errors stopping your Roku TV HDMI from picking up signals when connected.

Why Does My Roku Say No Signal

No one is happy when our electronics fail us, as in the case of your Roku displaying ‘nothing’ when you want to watch ‘something’. It’s even more frustrating if it happens right when you’re about to watch your favorite show.

This error can be the status of your device for a split second, in which case you’re lucky. However, it can also remain on your screen for a long time, causing you to seek solutions. 

For a first-timer, you might find it confusing to zero down on the main cause of the wrong signal. But, suppose the screen displays no signal despite having your HDMI plugged in. It means you already have an idea of what the cause is and don’t have to spend too much time figuring out where to look before fixing the error. 

Once you go through the various issues discussed in this guide, you’ll find yourself whizzing through the world of fixing your TV signal errors like a pro who’s spent years at it. The most common problems that cause this include:

  • Wrong input source selected
  • Clogged Port or HDMI
  • Poor HDMI cable connection Issue with Roku Device
  • Bug issue
  • Roku is down
  • Software not up to date

Depending on the issue you can identify from your careful observation, you will find different methods to fix each in no time.

1. The Correct Source Hasn’t Been Selected

Once you are sure your Roku player is switched on and connected but not receiving any signal, the first thing to check is the Input Source. As the name implies, the input source is the point of connection where the TV gets its audiovisual signals. 

Incorrectly plugging your HDMI cables into the ports will result in zero signal. Likewise, when you plug into the correct port but can’t seem to pick the right port to serve as a source for your TV, you will also get no signal.

So, generally, if your TV is rendering its signal from a source different from the one with an HDMI connection, you will not get any signal. An exception is when the wrong source you select is also sending signals (when you are using more than one source). So checking your TV ports and ensuring the HDMI is plugged into the correct source is one of the basic steps.

Fix – Choose the Correct Source

Roku and other TLC TVs have their default source set to HDMI1 port i.e. If you plug a Playstation to HDMI1 and Netflix to HDMI2, the TV will display visuals from the Playstation. So you have selected the wrong source if you had plans to enjoy Netflix instead of playing games.

The best way to fix this is to check if you are rendering from the correct source. Most TV remotes have the Input Source button to confirm where the signal is coming from, so press this to view the current source of the signal. If your TV’s source doesn’t have a connection to the right source on the screen, find the correct one and fix it by selecting it as the primary source.

For example, if your Roku player has connections to HDMI2, but the source selected is from HDMI1, you will get the NO SIGNAL error message. To fix this, you have to select HMDI2 as the correct source. Don’t rush when doing this because it sometimes takes a while (about a minute or two) after selecting input for the image to appear, so take your time.

2. Port or HDMI is Clogged

If the problem is not from the source, you can shift your attention to the HDMI and ports. The ports have tiny spaces that can accumulate specks of dirt over time. Ditto, the HDMI can also hold dirt in its holes, clogging the space meant for sending signals between the two devices.

The clogs can be due to prolong usage of the ports but they can also log into a newly bought HDMI or device. Hence, always check the space before connecting the two devices to save yourself stress.

If the dirt or material clogging it is big enough, the HDMI and port will not be able to connect or might have a weak connection, resulting in No Signal to your Roku TV. Hence, here is a method you can apply to sort any issue arising from a clogged port or HDMI.

Fix – Clean Out HDMI Port and HDMI Using Compressed Air

Removing the dirt or material causing the blockage is the only way to fix clogged ports. Compressed air or air dust is an excellent method to do this if the blockage is thick or difficult to remove by shaking or blowing the port with the mouth. 

However, ensure you are not plugging both devices before cleaning to avoid electric shock or risk damaging the features. Avoid using foreign materials to clean too because they might damage the ports without rendering any real help.

When using compressed air, keep the air a few inches from the holes during the cleaning while maintaining short bursts of air at the dirt. You can stop cleaning once the port and HDMI are free of any material clinging to them or clogging the spaces. Then, plug it back in, check if they fit, and continue cleaning if not.

3. Poor HDMI Cable Connection

Even if the HDMI and ports are clean, you can still experience no signal due to poor cable connection. If the HDMI cable connection to the port is tight and secure, your Roku signal will either be weak or non-existent.

Keeping the HDMI connection for an extended period can cause poor connection or weak signal due to the long period of the cable’s connection.

The poor connection can also be due to damaged parts, which hinder proper port connection. Hence, for any problem resulting in no signal to your TV due to poor cable connection, you have four ways to fix it, as outlined below.

Fix 1 – Reconnect HDMI Cable

Roku works like any other streaming device, plugging into your TV using its HDMI cable. This connection transmits from your TV to the Roku device. Disconnecting and reconnecting your HDMI cable from the port can fix the signal error. 

When you disconnect the cable, you break the signal between the two devices and also remove any impediment that might be there due to prolonged connection. Reconnecting the cable returns the signal between the two points and a fresh start for the connection. 

Many users have confirmed that this approach is practical for fixing poor cable connections, even for other brands of TCL TVs, as long as the issue is a result of inadequate contact when plugged.

How to Reconnect HDMI Cables

1. Make sure you turn on both devices 

2. Unplug the power cord of both devices from the electric outlet

3. Remove the cable clip and disconnect it from the devices

4. Wait for a minute (60 seconds).

5. Plug the power cord back into the electrical outlet while the HDMI is disconnected

6. Turn the TV back on

7. Reconnect the HDMI cable

8. Turn on your HDMI-connected Roku device

Fix 2 – Switch Ports

It is possible to have a faulty port or one that’s incompatible with the HDMI cable. You should be good to go if you can identify and fix the defect immediately. Else, you are better off switching the ports and checking the other available ports to see if they can improve the signal strength or solve the problem.

If after cleaning the ports and you can’t seem to clean the debris, or the connection point is broken or rusted, you can try changing or repairing the port.

When you do either of this, ensure you change the input source to the new port in your TV settings as outlined in the first fix, or else you’ll still face the same error you are trying to fix.

Fix 3 – Use a Different HDMI Cable

Just like the ports, the HDMI cable holes can break or be faulty, so you can change your HDMI cable if you have more than one.

If you have two or more cables connected to different devices, swap the connection points and see if there is any difference i.e. the first cable can fit better into the second port and vice versa, creating stable signals for both sources.

If you notice the distance between the device and TV is too long for the cable, choose a different cable that is ideal for the distance.

Fix 4 – Replace HDMI Cable

Switching the cables might not fix the issue, which could mean the cable or port is faulty. Therefore, you can replace the HDMI cable (view on Amazon) with a new one and try it again.

When buying a new HDMI cable, ensure it functions correctly and the port is intact with no damage. If the error persists, try fixing the TV port or replacing it too.

4. Issue With Roku Device

All the previously suggested fixing options apply when you are sure your Roku streaming device is fully functional. If not, then you need to check it out too. If your device is not on, you must ensure it’s plugged in and turned on because sometimes it can be plugged in but still turned off without you noticing. 

We recommend any of the following fixes for problems involving your Roku device and not the HDMI or source selection.

Fix 1 – Connect Another Roku Device to see if it works

You can try connecting with another device to confirm if anything is wrong with your Roku device, then see if it fixes the error signal. If the No Signal error disappears with a new Roku device, something is undoubtedly wrong with yours.

In this case, try other alternatives for fixing issues with the Roku streaming device, including seeing a technician to fix it if it’s damaged. However, if the error persists, it might be an error from another source and that your device is perfectly fine.

Fix 2 – Check Your Wi-Fi Connection

Roku sends and receives signals from the internet via a wired or wireless connection to your home network. It works by streaming or downloading video from over the Internet, which you can watch on your Roku or TCL TV.

The streaming is why your Wi-Fi connection must be solid for your Roku device to receive proper signal. So check your Wi-Fi connection source and ensure that you have enough bandwidth or access to the internet before checking the device connection.

Wi-Fi connection issues usually display alert messages as “Low Signal Strength,” denoting the weak internet connection. You can fix that by reconnecting your device or granting access to the Wi-Fi network.

But this doesn’t mean you can’t fix the No Signal error by fixing your network connection. So, If you do not see any connection to the Wi-Fi, check the settings and fix it from there.

How to Connect Roku to Wi-Fi

1. From the Home Menu, select Settings

2. Then navigate to Network Settings

3. Press Set Up Connection and click on Wireless

4. You’ll see a list of available networks, so pick your network

5. Enter your password, and click Connect

Fix 3 – Restart Roku Device

If another Roku device could receive a signal after plugging it in, you should restart yours. Restarting the device allows it to boot freshly and remove any temporary crash or issue causing the weak signal. You can easily restart the device with your Roku TV remote in a few easy steps from the menu settings.

How To Restart Roku Device

1. Open the Home Menu and scroll down to the Settings Menu

2. Use the OK button to select the Settings Menu

3. Scroll down the list to choose the System Options and press OK to open

4. On the System Option, select Power and scroll down to System Restart

5. Confirm the Restart by clicking on the prompt Restart option displayed

Please note, if you are using an older version of Roku devices (i.e. the first and second generation), you may not be able to acces the “System restart” option when you check the Settings menu. But rest assured, all the newly released Roku devices give you the restart option through the Settings menu.

An alternative and perhap faster method to restart if you use an older version or want a quicker result, is to unplug your Roku power cord from the electrical outlet for ten seconds, forcing the device to reboot, then turn it back on. 

Fix 4 – Reset Roku Device

Meddling with the device settings can damage the functionality, which can cause a signal error. So, you might want to consider resetting to factory settings if you fear you or anyone else might have tampered with the device settings.

And if that’s not the case, you might also consider resetting if you’ve tried other means and aren’t getting any results.

However, please remember that you will lose all saved data, settings, and personal preferences, and your account will be unlinked from the device when you reset to factory settings.

How to Reset Roku Device

1. Select Home, scroll down to System and click OK

2. Navigate to the Advanced Settings and select it

3. Select Factory Reset at the top of the list

4. Click Factory Reset Everything on the prompt screen

Alternatively, you can reset your Roku streaming device with a physical button or pinhole, depending on the version you are using. This method is a backup for emergencies when your device is frozen and you cant do anything with the remote. Look for the built-in reset button or pinhole that you can find on the back or bottom side of the device.

You need to press and hold this button for ten seconds. But, if it’s a pinhole, insert a paperclip to do the same. Ensure the device’s LED light blinks in both cases to indicate a successful factory reset.

5. Bug Issues

Every electronic device is liable to bugs and crashes sometimes. Even though it sucks, you can hardly prevent it, and when your device picks one up, you still have to do your best to fix it. 

A device bug is different from a virus though, so you don’t have to fret when your TV catches one. Bugs malfunction in the program codes of a device, but they are usually temporarily logged into the device’s memory.

Therefore, you don’t need to call a whole department of developers to fix things. Clearing the memory or storage of the device will erase all files along with the bug, making it a quick and easy fix. However, you don’t get that lucky every time, so here are some methods you can use to fix bug issues on your Roku TV.

Fix 1 – Restart TV

If you’re using Roku TV, restarting it follows the same approach as the procedure for restarting the streaming device. However, if you are using the Roku device with a different TV, follow the on-screen instruction on your TV to restart. 

Allow it to switch off completely before turning it back on and establishing a new connection with the device. If you use a Roku TV, you can restart following the step-by-step guide listed below:

1. Open the TV Home Menu, scroll down to Settings and click OK

2. Scroll down the list to select the System Options and press OK again

3. On the System Option, select Power

4. Scroll down to System Restart

5. Confirm the Restart

Fix 2 – Unplug TV For 60 Seconds, Then Plug it Back In

An alternative to restarting is unplugging the TV’s power cord from the electrical outlet. The TV will immediately turn off, and every temporary bug logged on the memory will be removed, allowing it to assume its proper function.

You will lose any temporary settings or unsaved activity like restarting when you unplug the TV. Also, ensure it stays off for at least 1 minute before turning it on to allow this fix to work. You can press and hold the power button to switch the device off too, if you are skeptical about pulling the plug while the TV is plugged in.

Fix 3 – Factory Reset TV

Restarting only clears the temporary storage, allowing bugs in the primary torage to roam free. So, you can restore the factory settings of your TV if restarting doesn’t work.

For example, restoring the factory settings does the trick if the bug is a result of permanently logged error in the storage. 

But try to ensure you know the current settings on the TV if you weren’t the one that did the TV setup. Else you might not be able to restore the settings when you factory reset it.

For illutration, if you have a special screen effect on your TV that makes your gamescreen better or movie time clearer, you will lose those settings the moment you reset to factory settings.

How to Factory Reset TV

1. Select Settings on your TV Menu

2. Find and select the System Settings

3. Click on Advanced System Settings

4. Select Factory reset

5 .When prompted, proceed to click Factory Reset Everything

Fix 4 – Contact Roku

Contacting Roku support is one of your last options if you still can’t find any way to fix the issues with your TV. Fortunately, the customer support agents are everywhere online and easy to reach anytime you want to.

If you have any questions unanswered in this guide about the accessibility of Roku TVs, Roku streaming players, or malfunction on the Roku mobile app, contact the customer support via phone call, email ([email protected]), or chat with the live support on the website.

6. Roku is Down

It’s not common, but your Roku also experiences those paralysis moments when the server is down, or the services have issues and nothing seems to work.

During this period, you won’t be able to access the Roku services or make any online changes to your device, so your TV receives No Signal.

You won’t be affected though if your connection is to an offline source such as your laptop or mobile phone (as long as you change the input source to their HDMI).

Fix – Wait For Server To Get Back Online

You have limited options when the server is having issues, just like on any online-based service. You can only wait for the server services to get restored.

As earlier mentioned, it’s rare to experience this, but when you do, keep track of the downtime with You can also check the map feature on the website to confirm the affected areas and when the server will be back up online.

7. Software Out of Date

Even though it seldom happens, you can notice your Roku TV does not have the updated software version, and it can cause a No Signal error on the TV. The Roku’s developer team know this possibility, so they have included a manual method to update the firmware.

Although the firmware is a permanent software programmed into a read-only memory on your TV, you still need to keep it updated with the latest features and versions to fix bug errors and enjoy a better user experience.

Fix – Update TVs Firmware

Your Roku device should automatically update itself every 24-36 hours, but if there is a break in connection, it might not be able to. Also, sometimes the device doesn’t update fast enough, which can be affecting its functionality during that same period. So you have to update the software on the TV settings manually.

How to Update Roku TVs Firmware

1. Press the Home button on your Roku remote

2. Press the left direction button to navigate to the Menu

3. Scroll up and select Settings, press OK to select the option

4. Scroll up and click System

5. Select System Update (this screen shows the last update on the device)

6. Select Check Now to allow Roku to start checking for new updates

7. If the pop-up message displays “Update available,” you will see the option to Update Now or Update Later.

8. Select “Update Now”

9. Wait for your device to restart (you won’t be able to do anything until after the update and the device restarts)

But If there is a message saying “unable to update software,” there’s something wrong with your internet connection. You can rectify this by connecting your device to the internet and trying again. And when you get a message that says, “All software is up to date,” you don’t need to bother because the software is already up to date.
