Vizio is a trusted brand in TV due to its smooth OS and easy navigation. Users are experiencing a horrible experience with Vizio’s OS and navigation. However, the pictures won’t display but the sound works perfectly.
This bug could affect all TV models, including the latest. I did more research and found out. This is what I discovered after doing more research:
You will need to reset the TV or power cycle it if the Vizio TV doesn’t have sound and backlight, but does not show images.
These simple steps will resolve the problem instantly, as it is most likely caused by a software bug. Also, you should check for loose connections that could be affecting your pictures.
This is just the beginning. This article will provide you with a detailed look at the possible solutions to this problem.
How to power cycle Vizio TV
Power cycling is a good option since you can’t use the remote to turn on your TV. This simple procedure will fix all bugs, even the one that causes your TV to not show pictures.
To power cycle Vizio TV:
- Unplug the power cord by going to the power outlet
- Find the power button at the set’s back and press it for five seconds
- Reconnect the power cord
- Turn the TV on
The black screen will disappear if the problem is caused by a bug. You should perform power cycles frequently to avoid future glitches. If the problem persists, you should check the connections.
All connections should be checked
Loss of cable connections is one of the major reasons Vizio TV does not have pictures. The display could become dimmed or black if the cable connections are not correct.
Make sure that cables are properly connected
- If your set is still on, turn it off.
- If they are connected well, inspect HDMI connections
- Continue with coaxial and composite connections. Fix them if they become loose.
- Turn on the TV
Sometimes the cables can become worn. Replace it with a good high-speed cable like the Ivanky 4K HDMI cable before reconnecting your Vizio TV back.
Reset your Vizio TV
If Vizio TV has power but no pictures even with firm cable connections, you need to reset it.
The process is however different because you can’t use remote control. Vizio TV can be reset even without a remote.
Reset a Vizio TV without pictures
- If the TV is not turned on, turn it on and locate the buttons to the side.
- Hold volume down for 15 seconds and press the input buttons.
- You cannot see the pop-up banner on your screen so press the input button
- Give it a moment
- Now the TV will default to factory settings
You will most likely see the picture and hear the sound. Continue watching Smart TV as it was before you reset it.
If you don’t see the picture, then the problem is with the power board.
Replace the TV power board
If your warranty is still valid you can contact Vizio Technical Support to skip this step. Your warranty covers the replacement of the power board.
If the warranty is void, you can still get a replacement power board.
You should replace the power board if you have previous experience in repairing smart TVs. You don’t need any special tools to remove the TV and replace certain components.
To replace the powerboard, however, you will need these items:
- A fitting screwdriver
- To avoid misplacing screws, a place to keep them all
- A new power board for your specific TV (Available on Amazon)
- Fuses (if the TV blows a fuse).
The power board can be replaced if you own the three items. It is possible to replace it here:
- If the TV is still connected to the power, unplug it.
- Rear screws should be undone
- Find the fuse box on your TV. All Vizio models have five fuse boxes.
- Replace faulty fuses
- Locate the wires that are connected to the board
- Take out the wires and remove the board.
- Replace the power board with a new one.
- Connect the wires back
- Retract the rear cover
After you’ve removed the rear cover, your TV should now have both sound and pictures. You must use a powerboard that matches the model number.
If you have any questions about compatibility, ask your store representative.
If the TV doesn’t show images after you have installed the correct power board, contact a professional. A professional diagnosis can identify problems and replace the board.
If you’ve never replaced a TV before, it’s a good idea to contact a Vizio technician.
Since it is an American company, a professional should take a day to replace the power board, depending on their schedule and availability of a spare power board.
Contact Vizio customer care
Sometimes, the TV might not turn on after a professional diagnosis. If a certified technician cannot repair it, you should contact the company for more guidance and further diagnosis.
You may have to ship your set to their factory if necessary. Depending on the factory’s workload, the time it takes to repair your set can vary.
Contacting the company even if your warranty is expired is a good idea in two ways. It is the best way to ensure that your Vizio TV has genuine spare parts.
The company also has more experience in Vizio repairs, regardless of the model.
