Last week, I purchased a new 43" Insignia TV, model NS-43D420NA18. Two days later, after watching for 1-2 hours one morning, the screen went black, but the audio remained. I changed the stations, and they were all black, though audio remained. I turned the TV off and turned it back on. The picture was back.
About 15 minutes later, again the channel went black with preserved audio. The TV was not in sleep mode. I thought the problem might have been due to the Energy Saver picture mode (some inappropriate screen saver function?). I pressed the Menu button of the Insignia remote, and the menu appeared on the screen, and I changed the Picture mode to whatever was next on the picture mode list, and the picture returned.
I did a search on these forums; a couple older posts suggested the TVs in those cases probably needed repair, so I returned mine to the store and exchanged it for an identical new model.
A few days with the new set, and again today, after the TV was on for 1-2 hours, the screen went black and audio remained. Again this persisted with changing the channels. This time, the TV was in Custom picture mode. I pressed the Menu button on the Insignia remote, and menu options appeared. By changing the picture mode to whatever was next on the list, I was able to get the picture back. I cycled through the picture modes. I turned it off and on, and all seemed fine.
I was concerned there is a bug in the firmware, so I called Insignia technical support. The representative suggested I try a new electrical outlet. That's not an option given my home arrangements. My power supply seems fine and uniform. He then suggested I unplug the TV, leave it for 5 minutes, then hold in the power button for 30 seconds while it was unplugged, and then plug it back in. I did that. The rep hadn't heard of this problem and told me to call back if it redevelops.
I have not had more problems over the rest of today, but I'm still within the 15 day exchange window. I'm at a low level of patience with additional problems. Has anyone heard of this problem or heard of an easy explanation/correction?
If there's any potential relevance, I'll mention that I have Cox cable; I have to use their remote to change the channels on the cable box. I've used it with my old Insignia TV without problems.

Welcome to Community@Insignia!
I'm happy to hear our phone agent was able to help troubleshoot your TV. I'd like to see if there is more information we can offer, so to that end, I have ot.some questions for you:

- My cable is connected via HDMI1. I haven't tried it on another port yet.
- I don't currently have other devices connected to the TV. I have a DVD player that I'll eventually connect using the Yellow,White,Red connectors.
- I haven't contacted Cox. I haven't had this issue with my other Insignia TV.
So far, the problem hasn't recurred. I may get some time this weekend to leave the TV on for a while and experiment. I love the TV otherwise.
Thanks for your help and suggestions.

The problem has recurred this morning after watching TV for about 25 minutes. I turned it off and on, and it was back to normal. I then switched the cable input to HDMI2. It's looking like this TV is going to be returned/exchanged unless something miraculous occurs.

After switching to HDMI2, the TV began dropping video and audio simultaneously every few minutes. Black screen, no sound. Then it would spontanesouly come back to normal after approx. 30 seconds. I also noticed that the date was wrong in the system settings. I set it yesterday (I'm meticulous about date/time settings), and today it read 2/14/2018. I'd noticed previously it had said the year 2116 and 1980 and hadn't known what to make of it.
I brought my other Insignia TV to the outlet where this TV is, plugged it in, and immediately had zero problems, and this was sustained. The problematic TV is being returned.

After hearing the problem, a floor representative at the store recommended I change the HDMI cable if the problem recurred. At home, the problem did recur as I was adjusting the original cable. I swapped it for another HDMI cable and so far, all is good. I'll keep monitoring, but I'm happy I stuck with Insignia!

Thanks for swinging by to share a concern regarding your stepmom’s TV. Since NS-43D420NA16 isn’t SMART enabled it would need to be connected to an antenna, cable box, DVD Player, or streaming device to display a picture. The TV is reacting correctly due to there’s not an input for the TV to detect. The powering off is normal as that’s a part of the energy efficiency of the unit. Please let us know if you have any additional questions.

UPDATE: The HDMI cable change was a false solution. The problem has recurred after about 2 weeks with minimal TV viewing. Yesterday, the problem recurred, and I swapped the Cox Mini Box with my other Insignia TV. The problem recurred in 20 minutes.
Today, the problem (black screen on all channels but audio remains) has occurred 6 times, all in the same setting. We've had 3 Emergency Broadcast System severe T-storm warnings. For these, a series of low resolution text images are displayed on the screen, replacing the normal 1920x1080 images. The screen goes black after the audio tone beginning the severe T-storm warning. I use any of a few tricks to get the image back, and I see the emergency text. Then at the end of the emergency text screens, the screen goes black again, and I again have to intervene to get an image back.
I tried turning off the Overscan; the problem still occurred. I tried turning off adaptive contrast; the problem recurred. I reset Pictures Settings to factory default and set the Picture Mode to Standard. I've gone 20 minutes with no problems, but that means little. We've had no more Emergency interruptions...
3 consecutive Insignia 43" TV's (model NS-43D420NA18), all afflicted with the same problem. I'm not sure if the problem is in the TV's themselves or how they're reacting with my cable system, but I nevertheless wonder if another manufacturer's TV might not be affected. My 32" Insignia (which is not 1080) has no problems.
