How to Fix Vizio TV Black Screen of Death

How to Fix Vizio TV Black Screen of Death – So your Vizio TV has the black screen of death – the backlight is on, but there’s no picture. The Vizio TV black screen of death is incredibly frustrating, especially when it happens on a brand new TV. 

The black screen is a well-documented problem associated with Vizio TV. With such a problem, you can try solutions before deciding to throw away your Vizio TV screen into the scrap.

Cause of the Vizio TV Black Screen

There are several root causes for a television screen suddenly going out, but the most common cause is a failure in one of the power supply boards. Television may have one or more power supply boards in addition to a T-Con board and several other internal components. 

While these parts may sound complicated, they’re relatively easy to fix. Before you rush out to purchase the necessary parts, you should find out what the problem is. 

There are different issues that may affect your television. You should narrow down the problem before you attempt any repair.

Reset Your Vizio TV to Fix Vizio TV Black Screen of Death

If your Vizio TV has the black screen of death, you need to reset it. Unplug your TV and wait a full 60 seconds. While the TV is unplugged, press and hold the power button for 30 seconds. After the 60 seconds are up, plug your Vizio TV back in and it should work. 9 times out of 10, power cycling a TV will fix the black screen of death.

Of course, there are times when the above solution does not fix the problem. In that case, the problem is usually a hardware issue.

Power Cycle the TV to Fix Vizio TV Black Screen of Death

Power cycling the TV is also a simple way to troubleshoot the black screen of death, but it’s an effective way to fix software glitches that stop your Vizion TV from displaying. Here’s how:

  1. Power off the TV.
  2. Then, unplug the television from the wall.
  3. Now, press and hold the “Power button on the side for about 5 seconds” or “On the remote control.”
  4. Disconnect all unnecessary devices.

After performing the four steps above, try to watch and see if the problem persists.

Check the Cables

You’ve tried both methods above, and you have a black screen. We suggest you take your time to check all connected cables on one. This will sort out the problem with any external sources.

Try to remove all cables one after the other, attach the back to the TV properly, and ensure you’re using high-quality HDMI cables.

Unmute the Screen

Vizion TV has Mute/Unmute features that permit users to turn off the screen if they are streaming an audio application to ensure the screen does not distract you. We suggest you deactivate this feature by holding the mute button on your remote for 3-5 seconds.

Disconnect all Unnecessary Devices

If you have any other devices connected to your Vizio TV, make sure to disconnect all of them to see if they were causing the issue. Also, avoid using the power strip, plug your TV directly into the wall instead.

Issue with Vizio TV Backlight

If your Vizio’s TV is on (the power light is green and you hear audio), but there’s no picture on the screen, it’s likely because one of the LED power strips on the backlight is faulty. 

To troubleshoot the issue, make sure the TV is powered on, and then take a flashlight (the flashlight on your phone will work too) and shine it close to the TV’s screen. We suggest turning off all the lights so it’s easier to see. If the screen is working, you will see a very dim image on the TV.

Use the remote to see if the TV responds to commands. We suggest testing the volume and input keys on the remote too.

You might need to move the light around to find where the TV’s user interface is on the screen. If you hear audio cues, you’ll likely see a faint image too. 

If, when you shine a flashlight on the screen you see a dim image, and the remote is allowing you to control the TV, that’s good news. It means the TV’s T-CON and mainboard are working as they should. In that case, the problem is most likely with the TV’s LED backlights. 

NOTE: while some of a TV’s components are easy and cheap to replace on your own, disassembling a TV will likely void the warranty. If your TV is still under warranty, We suggest contacting Vizio for further assistance.

Replace the Power Board to Fix Vizio TV Black Screen of Death

Replacing the power board can be complicated; both the method you use and the model number of the board will vary from television to television. However, it’s still a fix that anyone can do at home with minimal experience. 

You will require:

  • A soft cloth (ideally a towel) to protect your screen.
  • A screwdriver of appropriate size according to your TV.
  • A tray to put all the screws in so that you do not lose any.

Now carry out the following steps.

  • Lay your TV face down on a smooth surface.
  • Remove all rear screws using the screwdriver.
  • Locate all fuses in the TV. Most have five fuses.
  • If these fuses are blown, remove and replace them. Sometimes, fuses are the source of the problem instead of the board itself.
  • Remove all connecting wires to the power board for a while.
  • Now unscrew the power board and remove the older board.
  • Place the new board into position and carefully screw it into the proper position.
  • One by one, reconnect all removed wires.
  • Reassemble the rear cover and screws of your TV and put it together again.
  • Now plug in the television to a power source and test if the diagnostic works.
