The Chromecast has been one of the great inventions of Google. It has dusted old televisions to turn them into SmartTVs, while increasing the convenience and speed of sharing content with a screen. However, there are various problems that we can face in our day to day sending content to the Chromecast from our mobile.
Since Chromecast is a device whose installation is extremely simple, its problems come from complications, generally related to our network. Before blaming the device, we can try to find the source of the failure by doing several tests and going step by step , both with our mobile phone and with the device itself.
- Problems during installation
- Unstable video and audio quality
- Chromecast connected but nothing is visible
- If all else fails, other solutions
Problems during installation
These failures usually occur before even enjoying Chromecast, since our mobile is unable to find the Chromecast during configuration, so we will have to try the following solutions:
In this case we must make sure that the Chromecast is at a distance of between 4 and 6 meters from our mobile during the configuration. Otherwise, detection errors will occur.
Check the LEDs
It is important to check the signals that the device sends us thanks to its lights. When we turn on the Chromecast, the LED light should blink white.
Check mobile connection
We will have to make sure that our mobile is connected to the Wi-Fi network , which is active. We will not be able to configure the device if we are on the data network and the Wi-Fi is off.
- Close the Google Home application and reopen it.
- Deactivate and reactivate the Wi-Fi connection on the device on the mobile and reopen the Google Home application.
- If possible, try using another device (like a tablet) to set up your Chromecast.
Unstable video and audio quality
Another problem that we very commonly face with Chromecast is low-quality or unstable reproductions. In this case, it may be a problem with our connection, but also with the server of the app to which we are trying to connect. This is very common in all the video apps that we have on our mobile such as Netflix, Youtube, HBO or FlixOlé.
If the problem is Youtube
Keep in mind that YouTube uses flexible bit rate transmission, which means that videos may appear in lower quality at first, so it should improve after a few seconds. If the video is not buffered at the playback speed, a lower quality will be used for better playback.
For all other video applications
If we have launched the content of any video app and its result is still unstable or with interruptions, we must perform a series of checks to see if they solve the problem.
- Check that between our mobile and the Chromecast there is a maximum distance of about 4 meters. The Chromecast (or TV with Chromecast built-in) should be no more than 4 meters away from the router to ensure smooth playback.
- Verify that the Chromecast and the Android device are connected to the same Wi-Fi network channel (2.4 or 5 GHz). That is, if we have both frequency bands enabled, the two devices must be connected to the same one.
Low volume problem
This is another of the instabilities when sending content, since we can see it but the volume is too low. To try to fix it, we must check that our mobile is connected to the same network or linked to the same account as the Chromecast. Then we will open the Google Home app, click on our device and adjust the volume to increase it. The problem should go away.
Chromecast connected but nothing is visible
It is one of the most frustrating problems, since we believe we have done everything right, connecting the devices, downloading the Google Home app and synchronizing the device , but the screen remains black. In this case we will also have several possible solutions at our disposal to try to find the problem.
We will have to verify that the gadget is plugged directly into a power source with the original power cord and power adapter. We can also alternate between the connection with the adapter, and try to connect the USB cable directly to a USB port on the television to see if this allows it to connect.
In this case, the solution is to check that the television is tuned to the same HDMI input as the Chromecast. In most of the controls or if we control the TV with a virtual remote from our mobile, it can be verified with the input button, the source button, or the classic “source” button.
Restart the Chromecast
If after the previous steps, the screen is still black, it is advisable to restart the device. To do this we will have to disconnect the power cable from the device, wait 1 minute and plug it back in. It is important to know that if we disconnect the Chromecast from the HDMI port of the television, the device will not restart, so it will have to be done by unplugging it from the power supply.
If all else fails, other solutions
It is possible that nothing of result, which leaves us less scope to find solutions that do not go through the technical service. However, before that last step, we must try these possible solutions, which in many cases solve the problem at once.
Update Google Home
The official Android app that controls the Chromecast may be waiting for an update to fix known bugs. We can check it from Google Play, entering My Applications and checking if we are running the latest version of Google Chrome.
Reset the Chromecast to factory settings
Sometimes it is the only solution to be able to fix all the problems. This setting will return the device to its initial settings, which means that we can start over by eliminating possible settings that caused the problem. We will have two methods to be able to do it, the first of them is done from the Google Home app, from our mobile and is the fastest. The second requires touching the device itself.
- In the Google Home application : we open the application and tap on the name of our Chromecast device. Then we enter on settings and click on the right on the three access points to more options. Finally, click on “Reset factory status” and accept.
- From Chromecast device : This method requires the Chromecast to be connected to the TV. Then we press and hold the button on the device for at least 25 seconds or until the solid LED light starts to flash, the image disappears from the TV screen and the restart sequence begins.
