There is very little that is more frustrating than purchasing a brand new TV and it just stops working, or getting home from a long day to find out that your TV won’t display an image. Let’s get you back to your regular scheduled programming. 

After following the various fixes in the guide, you will be able to watch your favorite movies or play your latest video games like usual; no more black screen for you!

Fixing a Black Screen on Toshiba TV

Your Toshiba TV may have gone black because it is not powered on, it needs to be reset, a cable is loose, or the TV is overheated.

If your TV screen is black, you can try to:

  • Charge your remote or replace its batteries
  • Double-check all cables are plugged in
  • Replace the cables to ensure they are not faulty
  • Use a new outlet or power surge protector
  • Touch your TV; is it hot? If so, you may need to replace the heatsync.

What to do if the Audio Works

If you are able to hear audio from your TV, that is a great sign. If you hear audio but the screen is still black, either a setting has changed, a part broke, or a cable is loose. If the sound alongside your TV video picture has stopped working, that could be a sign that the entire system has failed. 

Read on to read some of the solutions we have come up with.

Check Power Connections

Double check that when you click the power button on your remote, the button is working. If your remote is dead, make sure to replace the batteries or charge your remote. If this doesn’t help, you can get a replacement remote here.

If you are pressing the power button on the TV itself, is it actually sending the signal to turn on? If not, the next section may solve your problem.

Check Cable Connections

Check the cables that connect to your TV, these are the HDMI cables and the power cord. Make sure they are securely plugged in. If they are, and you see no damage, such as nibbles from pets or dust inside the port, you may need to replace the cables. You can find replacement HDMI cables here.

Check to see if the connectors on each end, and the wires inside the cable, have any visible damage. Just know that it can be difficult to discern a faulty cable by sight alone. 

Check The TV Panel

The TV Panel is the TV screen. If the screen is black, you may have some issues with the TV panel. To see if the issue of your screen being black is caused by TV Panel issues, check for these things:

  • Are the corners intact?
  • Are they swollen?
  • Are there any cracks?

LCD and LED screens can be sensitive to scratches and cracks. A simple crack or scratch can disable the visuals or input seen on the screen. You may need to solve these problems with a TV repair person or through Toshiba support.

Hardware Failure

You may have problems with your input area (the place where your cables connect). On the other hand, you may have a power button that is simply disabled. The TV board (think motherboard) may also be broken. All of these issues can be fixed by a TV repair person, or if your warranty is still in effect, you may call Toshiba support and see where to go from there.

Overheating

If you can see the input modes or that the TV says “no video”, you may need to replace the HeatSync. 

For a temporary fix:

  1. Unplug any additional devices like Chromecast, Roku, or the FireCube.
  2. Turn off your backlight on each input setting.
  3. To do this, lower the backlight setting to “0” in the menu settings. 
  4. Now, plug back in your streaming device. 
  5. Turn it on. 

Your TV should now work! Here is a great YouTube video showing the fix. If you would like to learn more about Toshiba TVs, check this link out.

What Do I Do If I Can’t See Pictures or Hear Sounds Coming From My TV?

As we mentioned previously, no sound and no picture can be a symptom of a faulty system. If you have checked all the cables (including replacing them) and are sure the TV is receiving the signal to turn on (as in, the remote is connecting or the power button is working), then the entire TV may need to be replaced. 

Here is a step-by-step process to attempt: 

  1. Test out the power
  2. Test the cables
  3. Test the panel
  4. See if your TV is overheating
  5. Make sure you disconnect all external devices from the TV
  6. Hold the power button on your Toshiba TV
  7. As you press the power button, check to see if the power button is lighting up
  8. If not, verify the surge protector or outlet is working

If none of this is working, you may need an alternative solution.

Replace the HeatSync

If you can see the input modes or that the TV says “no video”, you may need to replace the HeatSync. 

For a temporary fix: 

  1. Unplug any additional devices like Chromecast, Roku, or the FireCube
  2. Next, turn off your backlight on each input setting
  3. To do this, lower the backlight setting to “0” in the menu settings
  4. Now, plug back in your streaming device
  5. Turn it on
  6. Your TV should now work

Conclusion

If you go through this list and still do not find a fix, there are repair shops that can take your TV, or you can have a repairman come to your home (probably easier for your 65 inch TV). They will at least be able to diagnose your symptoms.
