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."
