When your Vizio tv suddenly stops displaying content on its screen, you might think the TV has tripped off. However, when you discover that there is still a shining light in the dark screen, you should know your screen has displayed a black screen of death.
A fault in one of the power supply boards can cause the black screen of death on your Vizio tv. Most Vizio TV is built with multiple power supply boards beside the T-Con board. When there is a problem with any of the power boards, it could trigger the television to trip off.
This may seem like a problem that requires the service of an expert. It would interest you to know that you can fix some of the problems with little effort. The first thing to do is ascertain which part of the Vizio television has developed a fault. To check which part of the television is faulty, you can verify using these three test methods.
Test The Sound
You should test the sound to know if the television is making an unpleasant sound. Please turn on the television and increase the volume to listen to its sound output. To make things easy, you can try streaming a video that has excellent sound dexterity.
Try The Flashlight
If your Vizio television produces sound but not projecting images, that means the part that makes lighting is faulty. To ascertain the cause of the problem, you can do the flashlight test. This method requires that you shine a light on the television.
Get a flashlight and ensure that it has enough power. Stand about two inches away from the television screen, switch on the flashlight, and point it directly on the TV. If you can see an image after shining a light on the television screen, that means the inverter board in your television is faulty.
Check the Connections and Power
The last test you should conduct is the connection and power test. This will help you ascertain if every component of the television is working correctly. Check if all the connections are intact. After this, reset the TV.
