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. A 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 actually 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. Start with a sound test.
Perform a Sound Test
Use the “Flashlight Test”
If you have sound but no image, the component that produces lighting for the television is likely the issue. You can narrow this down even more by using the “flashlight” test. You need to literally shine some light on the issue.
Check the Connections and Power
Many times, the best solution is a simple one. Before you panic, make sure everything is working properly and there are no loose connections. Then perform a hard reset of the TV:
How to Fix Vizio TV Black Screen of Death
If you have tried all of these methods and have an idea of what the problem might be, here are a few ways to repair it.
Replace the Power Board
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 need:
A soft cloth or towel to protect the television screen.A Philips-head screwdriver. The size will vary based on the size of your television.A container to place all the removed screws in.
Replacing Other Components
If the inverter board or another critical component has gone out, it will need to be replaced in a similar fashion to the power board. However, if you don’t feel confident in your ability to repair the television without causing further damage, hire a repair technician to handle it. If your TV is still covered by the terms of the Vizio product warranty, reach out to Vizio Technical Support.
