Perform the following troubleshooting steps to fix the black screen on a Toshiba TV.

Restart Toshiba TV

  • First, turn ofF your Toshiba TV at the mains.
  • Next, press the power button on the remote to turn on the TV.
  • If the TV shows a black screen, use the power button on the set’s front panel.
  • If the TV shows a picture, the remote batteries are weak or dead. Replace the remote batteries with new ones and try turning on the TV with the remote again.

Restarting Toshiba TV is the most common method to fix the black screen issue. Ensure that any device, such as Xbox or Roku, attached to the TV is switched on as well before turning on the TV.

Check TV cables and audio/video input connections

Loose cable connections are the most common cause of a black screen on any TV set. Therefore, check the audio and video connections to ensure that there is no loose cable causing your TV screen to go black.

Furthermore, if you have any steaming device attached to your TV set, try detaching its cables and inserting them back firmly. Now check if the signals are coming from the device.

Also, a few Toshiba TVs have two video inputs, and users often use one of them to insert the digital cable converter. In this case,  your TV will not display any image on the screen. Therefore, use both the video inputs and see if this fixes the black screen problem.

Check power cable and socket

Another cable to check is the power cable coming out of your TV and going to the main wall. When the power cable malfunction, the TV either won’t turn on or exhibit a flickering power light. In this case, attach the power cable with another TV in your home and see if the issue persists.

If other devices are also having issues with the cable, replace the malfunctioning cable; otherwise, insert the power cable with another AC switch.

Check HDMI cable

Your TV can show a black screen on an HDMI channel due to a faulty HDMI cable. Therefore, inspect the cable for any visible signs of damage, although it can malfunction due to wear and tear.

One way of checking the HDMI cable is to use it with another TV. If the second TV’s screen also blackens out on the HDMI channel, it means that the cable is indeed faulty and you need to replace it.

Sleeper time Activation

If sleeper time is active on your TV, it will shut down within the set time and show you a black screen. To fix this, you need to go to the Toshiba TV settings menu and deactivate the feature from there.
