4/15/21 I had this problem too. I fixed it by unplugging the power cord then depressing the power button on the TV for 5-7 seconds. Plugging in the power cord and turning on the TV.

Thank you! I woke up this morning to this issue. I have a 24 inch and found it does not have a on/off button, so I just unplugged it for about 5-10 seconds. Plugged it back in and I was good to go!

Holy F. SAME WITH MINE JUST NOW.

I tried these things & it didn’t work. Tried using my TV remote & watching from a different input besides cable tv, and it worked fine. That told me that my cable was the issue. Rebooted my cable box per directions online and it fixed the issue.

Same thing on my tv. Half dark. VIZIO. Unplugged wiped dust off tv then plug in again. It fixed the problem.

jeff bad backlight strip. Remove your power cord, then remove the back panel. The backlight is in behind the panel and since this is a Vizio, repair manuals are not easy to come up. You'll have to experiment or check youtube to see if you find a Vizio backlight repair. This video should help you out and this one is a general one on how to replace the backlight strip.

The Visio Support site helped me (via a google search). Do this before taking the extreme measures of opening up the unit:

Using the Visio remote, press the Menu button, then System>Reset & Admin>Soft Power Cycle>Yes. 20 seconds later I was good to go.

If you don’t have the Soft Power Cycle feature on your unit, you can unplug the unit from its power source, then press the TV’s power button on the side for 3 seconds, plug the cord back into the power source, then turn on the TV.

If this doesn’t work, there are other steps which were unnecessary for me.

I don’t have a power button on the tv. Vizio E700i-B3?

Thank you so much! This worked for me right now.

I tried this and it went to a very small screen on the upper left corner?? Fixer it by just turning off and turning tv but the dark shadow on top is still there. This is sooo frustrating

That worked for me too!!! Thank you!!!!

Dwhyink thank you!! That just saved us from having to open up the tv.
