How do you fix a 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.

NOTE: 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. Therefore, check the audio and video connections to ensure that there every cable is firmly tight to its respective port.

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 problem.

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

If other devices are also having issues with the cable, replace it with the new genuine one, and hopefully, this will resolve the problem.

Check HDMI cable

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

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 is indeed faulty, and you need to replace it.

Force Reset the TV

  • Turn off your Toshiba TV and unplug the TV’s power cord.
  • Leave the power cable unplugged for at least one minute.
  • Finally, plug the power cable back into the TV set and turn it on at the mains.

If the reset procedure doesn’t solve the problem, your Toshiba TV may need servicing.
