How to Fix Chromecast Flashing Red

You can make use of different methods to stop the flashing red light on your Chromecast device. Sometimes, a simple reboot might just be all you need. Other times, you need to perform a full factory reset.

Here is how you can rectify the problems of Chromecast flashing red:

Avoiding HDCP

Sometimes, “Chromecast flashing red problems” may be as a result of the High-Bandwidth Digital Connection Protocol (HDCP), which exists to prevent playing audio/or video on unauthorized devices. This protocol can sometimes interfere with the device.

Here is what you can do to check if this is the main cause:

  • Try to plug the Chromecast into a different device. Not all devices have HDCP, so you can check first-hand if this is causing the error.
  • Try to plug in your Chromecast to another HDMI port.
  • You can also use an HDMI extender to bypass this problem.
  • There are opinions on the internet that switching to a higher quality USB cable can fix the problem with the USB port.

Rebooting Your Chromecast

There are two ways to restart your Chromecast. It is either you perform a normal reboot or do a factory reset. Once you opt for a factory reset, have in mind that it will remove all your settings, preferences, and other saved data on the device.

Normal Reboot

A normal reboot will restart the device and pick up where it left off.

To reboot the device:

  • Turn off your TV and unplug it from the power source.
  • Unplug the Chromecast from the HDMI port and from the wall outlet.
  • Turn on the TV again.
  • Reconnect the Chromecast to the power source but not to the TV.
  • Wait half a minute.
  • Plug the Chromecast into the HDMI port.
  • Change your TV to HDMI input (the same port as Chromecast).

If you encountered Chromecast flashing red light for the first time and this method solves your problem permanently, then that is great. But incase the red light reappears, then you may have to do a factory reset.

Factory Reset

A factory reset returns the Chromecast back to its primary preferences.

Here’s how to do it:

  • Open the Google Home app.
  • Choose the device you want to reboot in the menu and tap it.
  • On the top-right, press the ‘Settings’ icon.
  • Then tap ‘More’ (three vertical dots).
  • Press ‘Reboot’.

Hard Reset

Each Chromecast device comes with a built-in button to reset it manually.  While it is plugged into your TV, you should press the button and hold it for around 30 seconds. The white light should start blinking and the TV screen should become black. This means that the reset has started.

  • Open the Chromecast WebApp.
