A Vizio TV experiencing a black screen, otherwise known as the ‘black screen of death,’ is a frustrating program, for sure. It can happen suddenly or over time the picture slowly dims until nothing is left. Why does it happen?
There’s very few reasons why a Vizio TV would be experiencing a black screen, but the most likely reason is hardware failure.
Why Vizio TVs Experience a Black Screen
By performing a few simple tests, you can determine whether or not hardware failure is the problem, as well as doubly confirm.
Checking… One, Two, Three
Your first move is to perform a sound test. Why? It helps narrow down the root cause your Vizio TV went black in the first place. Sounds testing can help determine if the issue is linked to a hardware failure, specifically the hardware responsible for supplying light.
Here’s what you do:
1. First, turn the volume up. Do you hear anything at all?
2. Still don’t hear anything? Double-check that you haven’t muted the TV. How about now?
If so, then the sound components aren’t the issue. You can further confirm by using a ‘flashlight test.’
Shining a Light in the Dark
Within the Vizio TV is a component that produces a light, which is necessary for the display of the images. Without it, it’s nothing but a black screen, but the sound still works.
Do you have a flashlight? If so, move on:
1. Grab a flashlight that has a good, solid light. The stronger the light, the better. Put fresh batteries in the flashlight if you have to.
2. Now, while staring at the black screen—your TV should be on—stand 2 inches away from the TV. Shine the flashlight into the screen.
3. Do you see the picture? Then that further confirms that the light producing component has gone bad. In other words, a hardware failure.
How to Fix Vizio TV Black Screen
Now, you might be feeling pretty bummed out, but there’s still a chance that it isn’t related to hardware and merely a hiccup with the system itself. That’s not uncommon. So, what can you do about it? Well, first off, there’s a quick reset method. If it doesn’t fix the problem, that’s when you should move to repair it or have someone else do it.
Reset Your Vizio TV
Before you decide to repair your TV, or someone else, there’s one more trick you can try: resetting the TV. It’s a simple process that will only take a minute of your time.
1. Turn off your Vizio TV and unplug it from the wall.
2. Find the power button and hold it for about 30 seconds.
3. Let go and plug it back in. If it solved the problem, that’s great. If not, then that’s unfortunate.
Replacing the Power Board
So, you’ve tried resetting and it didn’t work. That means the only option left is to repair it or have it repaired by someone else. If you don’t have any skills as a technician, this part isn’t for you. Instead, take it to a professional. However, if you want to handle it yourself, no one is going to stop you.
With that said, any damage that occurs while attempting to fix your TV is entirely your responsibility. Should you hurt yourself in an attempt to fix the TV, again, you are responsible. Techzillo is not responsible for your actions. Now, it’s time to fix the TV. Do note that the following steps are generalized and you’ll need to fill in the gaps based on the TV.
What you need is:
- A soft layer—a blanket it will do—to lay the screen on.
- A screwdriver, specifically a Philips-head.
Once you have all that, here’s what you do:
1. Lay the soft layer down. The TV screen is going to lay across it to prevent further damage.
2. Start by removing the screws. Here’s where your screwdriver comes in handy. Double-check that you have the right size or you could strip the screw.
3. While the back is removed, check that the fuses haven’t gone bad. A clear fuse is okay, but a dark one indicates a burn, which means it’s blown or about to blow.
Note: If you replace any bad fuses, it could be the source of your problem.
4. The power board will have one or more wires connected to it. There should be a small tab that you can gently, but firmly pull to remove them. Don’t worry! The wires are designed to be attached again.
5. Unscrew any screws holding the power board in place.
6. Take the new power board and install it in its place.
7. Now reconnect the cables and wires, but don’t place the cover back on just yet.
8. Plug the power cable in and, if you can, see to it that the picture came back. If it did, place the back cover back on. If not, check double-check all cable connections and try again.
