Ok, the tv is hanging on my wall and just started doing this all of a sudden yesterday, so you think it could be a few different things? And are these repairs pretty easy to do yourself?

Thank You Again!

I have Vizio 55” and screen goes black but still get sound. I have found that this is being caused by a bad connection between 2 of the boards in back. I have taken back off and carefully squeeze this connector point attaching boards together, and works fine for a few months. I believe the root cause is something to do with strain on tv body by being mounted on wall causing board connection spot to slightly move. When I fix and leave off wall, the problem does not happen again.

Have you tried going to your display settings and changing from vivid to another display? It worked for me.

by

I don’t believe that the settings display shows due to screen going out, but will test when this problem happens again in a few months.

My TV is not mounted on the wall and still went black. Changing the display settings worked for me. No issues since.

@dsmitty29 let us know what exact model this is. It is possible that this is caused by a bad power board which then causes your backlight to turn off, but can also be a T-con or main board issue. Let us know if only your picture turns off or if you lose sound as well and if the picture comes back on. You do want to try to reset your TV. Unplug it and push and hold the power button for about 30sec-1min then plug it in while holding the power button depressed. If that does not help, remove the back of your set and post some good images of your boards with your question. That way we can see what you see and could try to assist you further. Use this guide Adding images to an existing question for that

Update (02/08/2018)

@dsmitty29 "you can see the picture like that. " is indicative of a bad power board. The power board supplies the voltages needed by the backlight. Of course there is a possibility that your backlight LED array has failed or you have some loose cable. You have to check this out by removing the back and measuring the output of the power board. If the power is supplied but the backlight turns off, it's the array.

Thank you for the advice, the reset didn't work, it's a Vizio UHD 4K TV Model name: D65u-D2

by

Also, It will turn on and work fine for about 3-4 minutes and then the picture just shuts off, I turned the lights off and held a flashlight up to the screen and you can see the picture like that. The picture does not come back on after it goes off

by

It's hanging on my wall and just started doing this all of a sudden yesterday, are these things easy to fix yourself? Thanks again!

by

@dsmitty29 easy and difficult are all a matter of who is doing it ;-) It is really not very complicated. Most complicated will most likely be the removal of the back

by

I called a tv repair place, the guy said he doesn't think it wound be the power board

In regards to this issue with the D65u-D2 screen going black, here is what I’ve found with mine:

This issue started with my TV at 14 months old, just out of the manufacturer warranty (of course). After some research, I decided to change the power board. THIS DID NOT HELP. THE ONLY THING THAT WORKS IS CHANGING THE PICTURE MODE TO STANDARD AND THE AUTO BRIGHTNESS SETTING TO MEDIUM. Also, make sure all of your timer settings are changed to off. We have not had it cut out since!

It angers me that I have to do this, and that Vizio fails to recognize this issue, but at least I didn’t have to launch the TV into a dumpster.

I have a vizio 400k smart TV. I got it for free because of this issue. The screen would shut off after about 10 mins of it being on but the sound still worked. Just went in and changed picture settings to standard and turned off sleep and power mode. So far it's been about 25 mins and it's still on. Hopefully it stays that way but I believe it's fixed. :)

Changing picture mode to standard as well as turn off sleep and power mode didn't work. Unfortunately my life suck after having this TV for a 1 and 1/2.

by

Dryna, did you also change the picture to Med as well? It must be set to standard and med.

Hoping this works out visio just started doing the same exact thing had it for about the same exact time ( 2 years )

by

I have the same Vizio D65U-D2. Just out of warranty. Same exact problem. None of the proposed solutions above work. The only thing I’ve noticed I can do so far to keep the screen from going black is to keep it on Netflix (thereby using WIFI) with the cable box off so none of the HDMI cables are effecting the TV. So far, that’s it. If I watch TV or any DVR recorded program, blackout with audio working within 5 minutes. About to toss this piece of crap.

by

Tahiti Trust that sounds like a main board issue. All HDMI ports will go through the main board so will the WiFi but different circuits on the board

As frustrating as this is, I have found that changing the picture to Standard also works for me. I have a Vizio 65” tv bought on black Friday 2yrs ago. Just like Jake said, not long after being out of warranty the screen went black with audio. called Vizio and they refused to acknowledge the problem. Thats the last time I buy a Vizio, they are junk.

**********************************

Update, I have replaced the T.con card on it and while it didn’t fix my problem I noticed a minor improvement. I was able to switch the picture to vivid with the “auto brightness control” set to high and it remained on. For Best picture quality you want this function off and not on high. But this is an improvement over what I had before. If I change the auto brightness control to off, the TV still goes black with audio in the background. The T.Con itself was only $25 at Amazon. So for me worth the investment and keeps me going a little longer.

Changing the picture mode to standard also worked for me. The picture is not as good but at least there is a picture. Time to start saving for a non-VIZIO product. My tv is 2 1/2 years old.

It just started today with my  Vizio D65U-D2, too.  Standard and Medium seem to be working.  Mine is about 2 1/2 years old as well.  12/9/2018
