As an owner of a Chromecast device, I know all too well the frustration of having sound but no video. I’ve spent countless hours trying to troubleshoot the issue and I’m here to share my experience and the solutions I’ve discovered. In this blog post, I’ll discuss the common causes of Chromecast sound but no video, as well as how to fix the issue.
This could be the result of a problem with connectivity, power input, cables, ports, the TV, or the Chromecast device itself.
|Tips for troubleshooting Chromecast connection issues:
|– Ensure that your device and Chromecast device are on the same Wi-Fi network.
|– Make sure that the Wi-Fi signal is strong enough for steady data transmission.
|– Check that the Chromecast device is plugged directly into a power source using the supplied cable and adapter.
|– Try rebooting your TV, unplugging the Chromecast device, and switching to the correct HDMI port.
|– Try using a different HDMI cable if the issue persists.
|– If none of the above steps work, consider rebooting or factory resetting the Chromecast device.

1. The WI-Fi Connection Is Unstable
The first reason for a black screen with the sound intact is an unstable internet connection, especially if you’re using a Wi-Fi signal.
To fix this issue, check that not only both the device you’re casting from and the Chromecast device are connected to the same Wi-Fi network, but also that the signal is strong enough to maintain steady data transmission.
If you suspect that your signal is unstable, try turning your Wi-Fi router off, waiting for at least 10 seconds, and then turning it back on.
2. The Power Source Needs to Be Checked
If there’s an issue with the power source feeding the Chromecast, it can lead to outputting sound but no video.
To fix this, check that your Chromecast device is plugged in directly to a power source. The supply of power should be steady without interruptions, so it’s best to use the power cable and power adapter that came included in the Chromecast box.
After that, try unplugging your Chromecast device from the power source and then plugging it again. Switch on the device and see if the problem has been resolved.
To make sure your Chromecast device is receiving power, check to see that the LED indicator on the device is lit up. If the LED light indicator doesn’t turn on, you should check whether or not the USB port is working properly.
A faulty USB port could lead to unsteady power input. The same goes for a faulty power outlet.
3. The TV Is Glitching
If your smart TV is glitching, it can end up playing sound without video when you use your Chromecast. To fix this issue, reboot your TV as follows:
- Turn off the TV.
- Remove the TV’s power cable from the power source.
- Unplug the Chromecast device from the TV’s HDMI port.
- Unplug the Chromecast device from the power source.
- After at least 60 seconds, Plug the TV’s power cable back into the power source
- Turn on the TV.
- Plug the Chromecast device back into the power source and switch it on. Don’t plug the Chromecast device back into the TV’s HDMI port yet.
- Wait at least 30 seconds before reconnecting the Chromecast device to one of the TV’s HDMI ports.
- Change the TV’s input to the same HDMI port as the Chromecast device and check if it’s working.
4. You Chose the Wrong Input Channel
If your Chromecast is playing sound but no video, the problem may be that you chose the wrong input channel. You’d be surprised at how often this happens!
To switch between HDMI ports on your TV, access the input options using your remote control and simply change the selected port.
5. The HDMI Port or Cable Is Faulty
If you’re sure you got the right HDMI channel, then the problem may be with the HDMI port or the cable themselves.
You can check the HDMI port first by unplugging the HDMI cable coming from your Chromecast device and then plugging it again to see if the black screen is still there. If there are other HDMI ports in the TV, try plugging the cable into another port and see if the device displays normally.
If another HDMI port works, then the problem is with the port you started with. If none of the ports work, then try a different HDMI cable as the one you’re working with could be defective.
