What causes LG TV screen to go black?

Are you curious about why your LG television has a black screen? Then view the causes below.

  1. Loose or disconnected cables: If the cables connecting the TV to the source (such as a cable box or streaming device) are loose or disconnected, the screen may go black.
  2. Input source is incorrect: If the input source is set to the wrong option (e.g. HDMI when trying to watch cable TV), the screen may go black.
  3. Power issue: If there is a power issue, such as a blown fuse or a malfunctioning power supply, the screen may go black.
  4. Software glitches: Sometimes, software glitches can cause the screen to go black. Updating the firmware on the TV can help fix this issue.

  6. Defective backlight: A defective backlight can cause the screen to appear dark or black.
  7. T-con board malfunction: A malfunctioning T-con board can cause the screen to go black, this is a component that interprets the signal and controls the backlight.

How do I fix black screen on screen mirroring?

If you’re experiencing a black screen while screen mirroring to your LG TV, there are solutions that may help you resolve the issue.

DRM

First, make sure you’re not using any DRM (Digital Rights Management) video platforms. Screen mirroring copyright protected videos can cause the screen to blackout.

Application developers have the freedom to choose whether or not they allow screen mirroring, with big companies like Netflix, Disney Plus and Apple TV+ choosing to block this feature. AirBeamTV has no influence on this. When a party – like Netflix – has decided to enable DRM during screen mirroring, we cannot change that.

If you’re wondering if a particular app allows it, there’s an easy way to check:

  • Open the app on your iOS device.
  • Start recording via Control Center > Screen Recording.
  • Watch back the recording in Photos.

If you see the screen recording of the app you were using, then all is good! However if nothing displays then that application has blocked Screen Mirroring.

Update your devices

Second, make sure you have updated the latest firmware available on your LG TV set as well as any relevant applications – obsolete versions can also lead to screen mirroring blackouts. If this fails to fix the problem, try rebooting your device and initiate screen mirroring once again.

Netflix app shows black screen

Here are several reasons why the Netflix app on your LG Smart TV might be showing a black screen. Some of the most common causes include:

  1. Internet connection: Make sure your internet connection is working properly and that your TV is connected to the network. Check to see if other apps or websites are working properly.
  2. Outdated app: Make sure the Netflix app on your TV is up-to-date. If it’s not, update it through the TV’s app store.
  3. Account issue: Check to make sure your Netflix account is in good standing and that you are logged in to the correct account.
  4. Compatibility issue: Some older models of LG Smart TVs may not be compatible with the latest version of the Netflix app. In this case, it may be best to check with the manufacturer to see if there is an update or if the app can be replaced with a compatible version.
  5. Cache issue: Sometimes, the cache on the app can cause it to malfunction, in this case you can try clearing the cache and data from the app.
  6. Software Glitch: Sometimes, the software glitch on the TV can cause the netflix app to malfunction, in this case you can try a factory reset on the TV or check for firmware updates.

It could also be caused by a DRM issue. Read more about it in this extensive DRM article on our website.
