Google Chromecast has found its place in a huge number of smart homes today. It is a Google-designed technology that uses our WiFi and allows us to “cast” different media files from our mobile devices to Google Chrome compatible TVs and speakers.
While this sounds wonderful, there are situations where we can experience some issues with our Chromecast device. The state of the Chromecast device is indicated by the LED lights on it. One such LED light indication is the Chromecast blinking white light and having no signal.
It is good to know that we can do something to fix this, but first we have to understand what our Chromecast is trying to tell us.
No matter which generation of Chromecast you are using or whether you have a Chromecast with Google TV, there is a LED light indicating the current state of the device. And if you notice that it is blinking white the official explanation is “Chromecast is disconnected or needs to be set up.”
Well, we can say that this helps a little, so now we are going to describe the most frequently used solutions that have helped others get rid of the issue and enjoy their Chromecast as before.
The following solutions are the ones that have helped different users get rid of the blinking white light on their Chromecast. So, take your time and try these ones one by one.
Disconnect And Reconnect Everything
A loose connection can be a real problem mainly because we can’t notice it easily. This is why we recommend disconnecting every connection starting from the HDMI port at the back of the TV, The USB cable on the Chromecast device, both ends of the power cable until you reach the electrical outlet.
Poor WiFi Signal? Move Them Closer
In case your WiFi router and your Chromecast are too far from each other it is possible that the WiFi signal is poor. This can happen if you have moved your router to a different position, or the Chromecast device. If this is the issue, try moving the Chromecast closer to the wireless router and vice versa.
You can also try repositioning your Chromecast using an HDMI extender. Maybe it doesn’t receive the wireless signal well because it is usually placed behind the TV in a cabinet. An HDMI extender will allow you to place the Chromecast in a better position.
Check The Input
Press the input button on your TV remote. In the menu on the TV check whether the correct input is selected. If it isn’t, navigate to the correct one using the UP/DOWN keys and click OK to confirm the selection.
While you are here, try connecting your Chromecast to another HDMI port. Most TVs today come with more than one HDMI port so try connecting it to the other one and select it in the input settings.
Change The Power Source
Most people use the USB port on their TV to power the Chromecast. If you are experiencing the white blinking light and no signal issue, try using another power source for your Chromecast or connect it to a separate power adapter.
Restart Your Network
Most of the problems we have with electronic devices today can be solved with a simple restart. In this case, we recommend restarting your network, this includes both the modem and the router. The entire process is pretty simple and, in most cases, it is a working solution. So, let’s try it!
Disconnect the modem from the power source, and in case it has a battery, disconnect it as well. After that disconnect the router from the power source. Leave these disconnected for a few minutes and then connect the modem first. Connect the battery as well if there was one. Turn it on and wait for it to stabilize. After that, connect the router back to the power source and turn it on. After it boots up completely, check whether you can connect your Chromecast and try it. If this doesn’t fix the issue, try the following.
Restart Your TV
We have explained why you should restart your devices when you come to a certain problem. Just like before we recommend turning off your TV. Disconnect it from the power source. Give it some time and then plug it back in. Turn it on and test your Chromecast.
Are Location Services ON?
Check whether your smartphone is causing the problem – make sure that Location services are on. Allowing Location Services is required for the Home app to access your WiFi and to be able to connect to the Google device.
If you are using an iPhone, unlock it. Then tap the Settings icon, scroll down to Privacy and tap on it. You will see Location Services at the top. Make sure it says ON.
If you are using an Android device, unlock it. Then tap on the Settings icon, and then on Location. Make sure the toggle button is set to ON.
