DO NOT BUY VIZIO TVs. D50U-D1. Sudden Black Screen. Panel Defect.

I contacted Vizio directly. Sent them photos etc and copy of my receipt. TV was years old when this occurred so no warranty and they do not stand behind their products.

They told me it's a "panel defect" and repairs would be "uneconomical." Panel "defect" to me means I purchased the TV with a defective part(s) that wouldn't last.

They saw the purple ring so they knew it was not a board issue that can be fixed for $ I asked and he said no, it would cost more to fix this issue than buying a new TV.

Vizio is well aware of the 'black screen' issues with their TVs but they DO NOT CARE! I won't even get into the conversation I had with a guy calling himself "Francis" at Vizio because I'm still livid.

I asked him "How long should smart tv's last?" and he REFUSED to answer the question obviously because it would make the company he works for look bad.

So after dealing with this nightmare all I can say is DO NOT EVER, EVER, EVER BUY A VIZIO TV because they don't even last years with normal ( hours per day) use. I have read HUNDREDS of stories just like mine. You're watching a show. Everything is good and then BOOM, screen goes black. TV is toast. It doesn't even start to go bad! It just goes. Done.

I own 2 M Class 60" curved Samsung tv's that are phenomenal and I will be buying a 3rd.

Stay away from Vizio! Their tv's are trash, they KNOW FULL WELL they're defective but they don't care. "Francis" from Vizio actually told me that the issue with my TV is "on you maam." THAT is what he said to me! That the "panel defect" issue with my TV is my fault and my problem! Like I said, DON'T buy Vizio. Their TVs are horrible and their customer care/consideration/respect is just as ugly!

DefaultVizio D55U-D1 No Picture

I am trying to troubleshoot a TV for a friend to save it from the landfill. When I turn on the TV, the screen is black. No LED backlighting. Tried the flashlight test but no picture. The front led indicator comes on.
Here are the voltages on the 16 pin connector on the power supply board.

TV plugged in but OFF:
+5V +12V +12V +12VA 3D_ON ON/OFF


+5V +12V +12V +12VA PS_ON DIM

TV plugged in and ON:
+5V +12V +12V +12VA 3D_ON ON/OFF


+5V +12V +12V +12VA PS_ON DIM

The voltage on the connector that powers the LED driver board and is marked on the power supply board as +24V reads as V when the TV is on (and 0 volts when it is off). On the Main board when the TV is off, LED is solid red. When the TV is turned on, LED has both the blue and red LEDs on solid.

I do not see any bulging caps. The boards seem clean but the Main board has some fine powdery residue across much of it (but not on the back of the plastic housing). I was able to wipe the residue off with a pad with some isopropyl. The electrolytic caps on the main board are not blown or bulging.
The fuses on the power supply board are all okay. Cannot figure out if it is the power supply board (because I read V instead of 24V where it powers the LED driver board) or if it is something on the Main board. What do both the blue and red LEDs being on solid on the main board indicate?

Any suggestions on how to troubleshoot further?

Thanks.

How to Fix Vizio TV Black Screen of Death

If your Vizio TV has seemingly displayed the black screen of death for no apparent reason, there's a potential shining light in that dark, dark screen. Here are a few ways to fix the Vizio TV black screen of death. 

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

  1. Turn on the TV. 

  2. Listen for sound. If you hear nothing, try to stream something you know will make noise.

  3. Ensure the volume is turned up.

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. 

  1. Find a bright flashlight and ensure it has power.

  2. Position yourself about two inches from your television screen and shine the light on the TV.

  3. If you can see an image on the screen with the use of a flashlight, it means the inverter board in the television has gone bad. 

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:

  1. Turn off the television and unplug it. 

  2. Press and hold the TV's power button for 30 seconds. 

  3. Release the power button and plug the television back in. 

  4. If you're trying to test the picture from a device like a cable box, swap it out for a different device. If this fails, try to access the setting menu on the television.

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.
  1. Lay the television face down on a prepared surface. 

  2. Remove all the rear screws with the screwdriver. 

  3. Find all of the fuses on the television. Most have five. 

  4. If any of the fuses have blown, replace them. A blown fuse can often be the source of the problem, rather than the board itself. 

  5. Locate any wires that connect to the power board and remove them.

  6. Remove the screws that hold the power board and remove the old board.

  7. Place the new board into position, then carefully screw it into position.

  8. Reconnect all of the wires and cables.

  9. Replace the rear cover of the television and secure it.

  10. Plug the television in and test if the repair worked. 

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 Vizio TV is still covered by the warranty, reach out to Vizio Technical Support.
