Chromecast Blue Screen (Causes, How to Fix)

Chromecast is such a compact gadget compared to the power it brings to your TV. It can directly stream content from your phone without compromising on quality.

However, you couldn’t have guessed that such a small-sized gadget would paralyze your TV. It’s no good news on Friday night when your TV shows the blue screen. So, what’s the culprit behind the Chromecast blue screen?

Your TV can show the Chromecast blue screen due to minor glitches, which can be simply tweaked by rebooting your TV or resetting Chromecast. However, sometimes the blue screen problem can go deeper, and you might need to change the main board of the TV.

In this article, we’ll touch upon some of the most common solutions to the Chromecast blue screen issue.

How to Fix Chromecast Blue Screen?

It’s not your lucky day if your TV screen is stuck on blue because of Chromecast. It’s true that users have rarely complained about the Chromecast blue screen, but it still happens.

You don’t need to lose hope, though. Here’s our troubleshooting list:

Reboot Chromecast

Here’s how to reboot your Chromecast through a phone or tablet:

  1. Make sure your phone or tablet is connected to the same Google account as your Chromecast.
  2. Go to your Google Home app.
  3. Find your device’s tile, then tap and hold it.
  4. Tap the gear icon in the top right corner to open the Settings.
  5. Tap More Settings, then tap Reboot.

Beware that you can’t reboot Chromecast by unplugging its TV HDMI port. So the other option is to go through the following steps.

  1. Disconnect the Chromecast device from the power cable.
  2. Wait for one minute.
  3. Plug Chromecast back in.

Ensure Adequate Power Supply

Chromecast’s smart design allows it to get its power supply directly through the TV. You can simply plug it into your TV’s powered USB port.

However, in case you’re facing the stubborn blue screen, your Chromecast might not be getting sufficient power through the USB connection to the TV. 

Thankfully, Chromecast comes with a Micro-USB power adapter in its box. You can use the USB adapter to try and connect Chromecast directly to the electricity socket. This should provide a more reliable power supply, which can fix the blue screen issue.

Clear the cache of your Chromecast on Google TV.

Go to your profile icon and select Settings, then System, then Storage, then Internal shared, storage then Cached data. Select “Clear cached data for all apps,” then click Ok.

Disable Picture in Picture

Picture-in-picture is the beloved feature that allows you to watch YouTube TV while surfing the Internet or chatting with friends. 

When Picture-in Picture is turned on, your videos will shrink into a compact video player. You’ll be able to freely move it around as it hovers above the home screen or other apps.

Surprisingly, if this feature is turned on, it might be the hidden culprit behind the Chromecast blue screen. Here’s how to turn Picture-in-picture off:

  1. Open the Settings menu on your phone or tablet.
  2. Tap Apps.
  3. Then go to the Advanced section.
  4. From there, tap Picture In Picture.
  5. Toggle Picture In Picture to off.

After that, clear your device’s cache, data, and cookies. Then, restart your device.

Reset Chromecast

You can reset your Chromecast by pressing and holding the button on its back for around 30 seconds. Keep holding the button until a factory reset screen shows on the TV, then go through the setup procedure again.

Alternatively, you can reset Chromecast from your phone or tablet. We need to note, however, that this method will only work if you can access the same network you used to set up Chromecast.

Here’s how to reset Chromecast:

  1. Go to Google Home on your device.
  2. Tap and hold your device’s icon.
  3. Tap the Settings icon from the top right section of your screen.
  4. From there, tap More.
  5. Tap Factory Reset twice.

Replace TV Main Board

If you’ve tried all of the above solutions and the blue screen isn’t gone yet, then this might be the last option you want to try before calling technical support. The Chromecast blue screen might be persisting because of the TV’s main board

Unfortunately, if you decide to replace the main board, you’ll need to remove the screws and the TV back cover. It’s always recommended to consult a professional technician instead of opening your TV yourself. You might cause more damage by accident. 

To replace the motherboard, you can expect to pay well over $200. The good news is you can save more than half the costs by replacing the main board yourself. The task requires limited technical know-how and a few tools, though.
