I have sound but my picture keeps going black after a few minutes of
Any Ideas on what might be causing my picture to go black after watching a few minutes of tv? This Just started happening l!
@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.

@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.
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. :)
Folks, I have the Vizio 65” D Series and having the same issue “Screen goes black but still has audio”. This happens while using any device, on any HDMI port, as well as the built in Smart apps particularly . I've attempted all of the workarounds mentioned on the internet including working with Vizio support without resolution. After dealing with this for the past year or more and sifting through countless threads I believe I have finally found a permanent fix. Power draining, factory reset, changing picture mode, has no effect. These are all temporary workarounds on their own. Currently having the picture mode at Standard with Auto brightness off and backlight set to 75% seems to be holding up and have not had the “Blackout” since. This is unfortunate and Vizio should patch this defect. Let me know if this works for anyone else.
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 $25 at Amazon. So for me worth the investment and keeps me going a little longer.
Backlight to 63 works for me. Hold mute for a few seconds if the picture turns black. Then after holding the mute button a few seconds the led on the bottoM of the TVs bezel turns back on press the input button to change the hdmi or other plugged in inputs and it should turn back on for a few more seconds or minutes so you can change the backlight to 63 or whichever sweet spot you pick that works for your tv. 63 isn’t terrible but would be nice to see 100% backlight. You might need to change the led strips or computer chip for the backlight if this continues or gets worse. You won’t be able to take the tv apart it’s virtually impossible without creation tools ormachines to take the tv screen apart properly. These parts cost you around 25-60$ to replace but not sure how much labor would cost you. Estimate price would be around $300-400.00.
good luck everyone.
Vizio D65u-D2 turned the setting to standard and medium. Issue resolved. If I put it on Vivid, it shuts off again after a few minutes with audio only. Ordered the power supply to see if it allows me to use Vivid setting.

Friend gave me his D with black screen…I reduced backlight to 50 ran for 1yr until LEDs burned out. Like slow death.
Stick to P/Q models, still love my P65f1.
Funny thing my ex gave me the first Vizio for bday 2007?. It's like 22” . Weighs like 20 lbs and lasted longer than the marriage. Still running.
