When the Chromecast or the TV does not receive a sufficient power voltage, the device will not function properly and cause Chromecast issues when casting.

The simplest way to deal with this situation is to simply reboot both of your devices to start fresh.

Follow the following steps to reboot the Chromecast and your TV:

How to Reboot Chromecast?

  1. On your mobile, open the “Google Home” app.
  2. Click on your Chromecast under the Media Room.
  3. Tap on the “Settings” from the upper right corner.
  4. Click on “More” to access the advanced settings.
  5. Tap on the “Reboot” to restart your Chromecast.

Alternative: Unplug the Chromecast device, wait for about 2 minutes, and reconnect back!

How to Reboot Any TV?

  1. Unplug the TV from the power outlet.
  2. Disconnect all HDMI-connected devices. 
  3. Wait for about 5 minutes for a power cycle.
  4. Plug the TV back into the power outlet.
Tip: Keeping your device unplugged for longer also helps against overheating!

2. Switch to Another Power Source

As we know, the Chromecast can either be connected to the TV’s USB port to receive power or plug into a power adapter, hence directly to the wall outlet.

However, this allows us to test if the Chromecast will only show a black when connected via an alternative way to receive power.

How do Power the Chromecast using Adapter?

  1. Get the power adapter and the USB cable of your Chromecast device.
  2. Tip: You can use any micro USB to USB cable as well as any adapter!
  3. Plug the micro-USB port of the cable into the port on your Chromecast.
  4. Plug the other end of the cable (USB port) into the power adapter brick.
  5. Connect the power adapter to a nearby working power outlet to your TV.
  6. Wait until the Chromecast is powered on and turns on the light for indication.

That’s it, as soon as the TV connects to the Chromecast, you’ll be able to cast to TV from your casting device.

In case the screen still appears to be pitch black, continue with the next step.

3. Change the TV’s Input Source

If your TV is not set to the HDMI input port to which your Chromecast is connected, you will be able to cast, but you won’t see anything but a black screen.

Don’t worry, all you need to do is double-check your TV input source and make sure it’s set to the correct HDMI port.

Here is how to check the TV HDMI input for Chromecasting:

  1. Locate the name of the Chromecast HDMI input ports on your TV. 
  2. Locate and press the “Input” or “Source” button from the TV remote.
  3. Cycle between the different HDMI TV inputs using the arrow keys.
  4. Select the “HDMI 1” or “HDMI 2” on which Chromecast is plugged.
  5. Click the “OK” or “Enter” button on your TV remote control to confirm. 

Correct Source – Screen is Still Black?

If your TV has multiple HDMI ports, try plugging it into a different one because maybe the previously used Chromecast port is defective.

We recommend plugging the Chromecast into one of the back TV HDMI ports since they are less frequently used, hence more preserved.

4. Optimize the WiFi Connection!

If your TV and Chromecast works but black screen when casting, the problem is most likely with the device’s network connection.

Since unstable or weak Wi-Fi signals can frequently cause casting issues, especially black screen when nothing from the casting is able to load.

The Solution?

  • Connect casting and Chromecast devices to the same Wi-Fi.
  • Move the Chromecast closer to your router for better coverage.
  • Reboot the WiFi router to improve Wi-Fi signal strength.

How to Reboot the WiFi Router?

  1. Unplug the WiFi router and modem from a socket.
  2. Disconnect the connected cables from the router.
  3. Leave the router disconnected for about 5 minutes.
  4. Reconnect the cables back to the router and modem.
  5. Plug in the WiFi router and modem back into power.

Once your internet connection is stable and you are sure that all of your devices are connected to the same network, test casting to your TV.

5. Configure the Browser Settings!

The Chromecast dongle updates automatically as long as it’s connected to the internet, but when you’re using the Google Chrome browser, updates might be missing.

Here’s how:

  1. Open the Microsoft Edge browser on your device.
  2. Tap on the three-dot menu from the top corner.
