Display Intermittently flickers on and off - E55u-D0

I have a Vizio E55u-D0. When watching TV, the display intermittently flickers off an on in around 0.5 second intervals. Reading other questions, I’m fairly confident this is a backlight issue since the sound does not go out along with the image.

I’m wondering if the most likely cause is the power supply board or the LED array? When the screen flickers on and off, the entire screen goes dark, not just certain areas.

I’d say it’s highly likely that it’s an issue with the LED strips - suggest that you swap them all out, you can buy a replacement set at - https://www.shopjimmy.com/vizio-ic-a-vza...

Generic instructions to replace them can be found at - https://factory-reset.com/wiki/LCD_Backl... - it’s quite a delicate process to remove the LCD so be sure to check out some video tutorials on YouTube to get an idea of the process.

Usually an LED failure causes entire display to stay off not intermittently turn on and off

Sounds a lot more like a Driver issue something within the power supply or video board although I would start with the power supply in this case Since the video is able to display consistently and still maintain functions etc

And yes, I realize that I'm five years late to this but hopefully someone else could be helped😅
