1. Loose HDMI Connection

Loosening High-Definition Multimedia Interface (HDMI) connection on either the Display or Source end is a major reason why your Toshiba TV shows no video signal.

Whenever you need to move the cable slightly for any reason, the wires become disconnected from your TV, and it shows no input. Also, the open HDMI port causes a loose connection.

Placing thicker HDMI cables causes faulty connections. The thicker or poor HDMI connection fails to carry the signal to your Toshiba TV. As a result, it displays the “No Video” error message.

One of the leading causes of loose connection is plugging and unplugging the HDMI cable to the port frequently. The connection becomes loose because of the cable’s frequent change or extreme use.


Check your TV’s HDMI cable connection and adequately plug and connect the cable to the right place. Also, check the HDMI cable’s Source and Display end and make sure both the end’s connection is tight enough. At each stop, disconnect and reconnect your TV’s HDMI cable. 

Avoid placing thicker lines and don’t plug or unplug your TV’s HDMI cables to the port frequently. Check for the loosened HDMI port, and to tighten your TV’s open port, do the following:

  • Turn the HDMI-equipped back panel of your Toshiba TV.
  • Locate the port and remove the current HDMI cable from the port
  • Immediately below or above the port, you will get the small Philips screw. Detect the screw and use the Phillips-head screwdriver to tighten the port clockwise.

2. Selecting The Wrong Input Source

Toshiba TV has no video signal message means your TV is not receiving a signal from your selected signal source or external input source.

If you choose the wrong input source, your Toshiba TV will display no video or image, and it will show this no signal error message.


Go through your TV remote’s Input option and ensure you have selected the correct input source for your TV. Press the remote’s Input button, and you will get several input options. From there, select the HDMI port. 

When there are many ports available, then select the port according to the number. Also, focus on which service you are trying to use on your TV.  

3. Damaged HDMI Cable

The most obvious reaction of a damaged HDMI cable is your Toshiba TV says no video signalIt also causes inconsistent sound and color on your TV. Over time, your TV’s HDMI cable can go wrong or become damaged.

  • Improperly maintained or damaged input connectors
  • Bending or coiling the cable


Be gentle in using the HDMI cable in your Toshiba TV. If your Toshiba TV says no signal but everything is plugged in, you should check the HDMI cable which is carrying the signal to your TV.

However, if you find the faulty cable is creating this problem, you should do the following:

  • Replace the sheared cable, corroded internal wiring cable, broken HDMI cable, and damaged input connectors
  • Avoid frequently and roughly plugging and unplugging the HDMI cable
  • Properly maintain the input connectors

  • Replace the physically damaged or faulty HDMI cables, defective HDMI port, bad input connector, and overheating HDMI signal board.
  • Check your Toshiba TV’s HDMI cable and make sure it is properly connected.
  • Ensure your TV’s HDMI port is working perfectly
  • Make sure you replace the slow microprocessor, and your TV’s newly installed processor perfectly recognizes the video inputs and other resolutions.
