Roku devices are incredibly user-friendly and deliver a diverse selection of entertaining channels. Although Roku is an excellent video streaming solution, some users report screen problems (freezing, cutting out, having sound but no picture, etc.).
A common reason for a Roku screen freezing or cutting out is an unstable or weak Wi-Fi connection. To resolve this, improve the Wi-Fi signal strength by moving the router closer to the Roku device or eliminating signal obstructions. Additionally, restarting both the Roku device and the router can help re-establish a stable connection.
Overheating of the Roku device can also cause the screen to freeze or cut out. Ensure the Roku is in a well-ventilated area and not enclosed in a cabinet or near heat sources. If the device feels hot, turn it off and let it cool down for a while before restarting. Consistent overheating might indicate a hardware issue that requires attention.
Another possible cause could be outdated Roku software. Keeping the device’s software updated is crucial for smooth operation. Check for available updates in the Roku settings menu under “System” and “System update.” Performing software updates can resolve known bugs and compatibility issues that may be causing the screen to freeze or cut out.
This article will explain why your Roku screen isn’t working correctly and how to repair it without replacing your TV. We’ll also reveal why your Roku TV isn’t showing a picture at all!
Roku Screen Freezes/Keeps Freezing
Your Roku device can freeze for various reasons, but the three most common explanations are:
- Channel malfunctions
- Outdated software
- Congested cache
If the freezing seems to be related to an app or a channel, uninstall and reinstall the software.
If your Roku seems unresponsive when you open the menu, the memory is likely full. Delete any unused channels or apps to increase the device’s storage capacity.
How To Manually Upgrade a Roku Device
Your Roku may also be freezing because it’s out-of-date. Roku updates quite often to address any software glitches. Still, the system can ignore patches due to a poor internet link. You can manually upgrade the Roku unit by following the measures below.
- Push Home on your remote.
- Choose Settings.
- Navigate to System.
- Select System Update.
- Choose Check Now. Allow Roku to update if there is one available.
How To Clear a Roku’s Cache
You can also clear your cache by performing a soft reboot. This operation removes temporary data and resets the memory, which should resolve any ongoing freezing problems. Restart your Roku using the following procedure:

- Disconnect the power cable. If you’re using a Streaming Stick, unplug it from the HDMI port.
- Leave the Roku disconnected for at least one minute.
- Reconnect the power.
Roku Picture Cuts Out
When your Roku image cuts out continuously, the resolution on your TV may be to blame. This issue occurs most often when users’ Roku units are at the 1080p setting. To fix this problem, you can change the resolution to 720p or 480p.
But for those who prefer the crisp display of 1080p, consider a factory reset before disabling the auto-refresh function.
How To Factory Reset a Roku
Here’s how you can factory reset a Roku device:
- To return to the home screen, press the Home button on your Roku remote.
- Navigate to the menu bar and choose Settings.
- Press OK on your Roku remote.
- Select System.
- Choose Advanced System Configuration.
- Scroll to Factory Reset.
- Confirm that you want to do a factory reset. Allow Roku to complete the reset process before unplugging the power cable again.
After that, disable the auto-adjust mechanism by following this procedure:
- Navigate to the configuration menu.
- Choose Advanced System Settings.
- Scroll to Advanced Display Settings and select it.
- Go to Auto-adjust Display Refresh Rate and disable it.
Roku Have Sound but No Picture
If your Roku has sound but no image, it’s likely that your HDMI cable is defective. Replace it with a different line and check for improvements. While HDMI cables rarely fail, this move is worth attempting before going on to further (and more expensive) troubleshooting.
After replacing the connection, switch to a different HDMI socket, as the problem could be isolated to a specific port.
If neither of the previous approaches works, you may want to try attaching your Roku system to a different TV. This method will help you determine if the issue is with your device or your monitor.
Once you’ve confirmed the issue is with your Roku unit, use the pinhole on the back of your Roku to trigger a factory reset. Hold the reset switch for at least ten seconds for the machine to begin the reset phase.
Roku Keep Losing Picture
Similarly, if your Roku’s picture keeps disappearing, this is also a result of your HDMI link. Roku 4K devices need an HDCP 2.2-certified HDMI cable to function suitably. We suggest replacing your HDMI cable with a new HDCP-approved wire. It also helps if you attach your system to a separate HDMI port on your television to see whether this solves the problem.
Or verify that you effectively disabled the Auto-adjust Display Refresh Rate.
If none of these strategies fix the issue, try changing the screen size on your Roku device. Selecting the widescreen alternative resolves this problem for most users.
To do this, follow these steps:
- To enter the Settings menu, press the Star key. Or navigate to the Settings menu by clicking the Home button on the remote and then using the arrow keys.
- Select Picture Size.
- Pick Widescreen with the arrow keys.
Roku Has No Picture/Not Displaying Picture
If your Roku television doesn’t show an image, ensure that the television is on and that the device isn’t in standby mode. If the LED light is blank, the TV is on.
After verifying that the system is on, you can restart the television. On most versions, the power button is under the TCL emblem on the bottom of the television or the rear. Then, detach the power cable for thirty seconds to see if it helps.
If the issue continues, you may need to boot your unit into recovery mode, which is the most intrusive way of resetting your Roku TV. However, only consider this if the other approaches mentioned above don’t restore regular operations.

Once you activate Recovery Mode, your TV will need to reinstall the operating system from Roku servers or a USB flash drive. You’ll also need to reconfigure your unit to restore its previous settings.
How To Enter Recovery Mode on Roku
To activate Recovery mode, follow these steps:
- On the back of your television, locate the pinhole reset switch.
- Hold the reset button for at least 20 seconds using a pointed tool.
- Select your spoken language using the directional pad on your Roku TV remote and choose OK.
- Link to your home network by following the on-screen directions.
- Select Update Now.
Your Roku device will then restart and hopefully restore its image. However, this approach is only applicable if the unit displays anything at all. Otherwise, you’re better off contacting a Roku service agent to request assistance.
Why Is There No Picture on Roku TV?
If your Roku TV isn’t displaying a picture, the most popular explanations are:
- Your television is set to the incorrect input source. Choose the HDMI input that corresponds to the one your external player is linked to.
- The video cable isn’t attached correctly. Ensure that the video wire is securely attached to both the back of the Roku TV and the HDMI connector on your external unit.
- The television has developed a fault. Where possible, connect an external player to a separate television to determine whether the issue is with the television.
Since the most often encountered problem is with the wrong source information, push the source button on your controller to loop through the available inputs. Your unit can show a menu rather than selecting the sources automatically. If this is the case, use the arrow buttons on the remote to choose the appropriate input and then hit Enter.
In both instances, if the input doesn’t activate the picture, the TV will show an error message.
