Blinking Effect of Toshiba Tv Black Screen

  • Check that the Tv is not in Energy-saving mode
  • Change the input source to see if the issue involves a TV or a variable.

Fixing a Black or Blank Toshiba Tv

When your TV is switched on, and the power light is on, but no image or sound is heard, check the following:

1. Switching on the Tv

Check that the TV is enabled by clicking the power button with the remote or the set’s front panel. Ensure the component you’re using is switched on (Xbox, Cable, SAT, ROKU).

2. Right Cables and Cords

Double-check that all cables and cords are firmly attached to the television inputs and component outputs. For example, if your tv is video two input, but the digital cable converter is plugged in video one input, the Tv will not have sound or image display on the screen.

Double-check that you’re on the correct input, as some TVs will display a black screen if there’s nothing plugged into the current port.

3. Loose Cable

Reset the audio and video input connections to make sure it’s not a loose cable causing the TV’s problem.

Check for the connected cable devices and disconnect them, then plug it back and check if the signal will come up. Having loose cable devices can make your Tv not respond or go blank.

4. Replacing Your HDMI Cable

You may need to replace your HDMI cable because there might be defects that trigger the issue of the blank or black screen.

5. Turn off the Power Saver Mode

Some TV sets will turn off the screen automatically, but it also produces sound when movement is not detected. It may be as a result of Energy Save mode or power saver being activated. Check that the TV is not in energy save mode, if it’s in energy mode, take it to the normal display mode using your remote.

6. Reset the Tv

Please switch off the TV for some minutes, then press and hold the Tv power button on for about 20 seconds to reset it. If after doing this, it still doesn’t work, it might be problems with a defective power supply board.

7. Faulty Power Supply Board

If the power supply board is faulty, the TV will have the power light on, but no sound or picture will display. If after trying out all these methods and your TV screen is black, consider changing your Tv’s power board.
