I know there is a picture on the screen because I get sound and sometimes a backlight picture. However I can’t get the back light to come on sometimes and right now it’s been weeks since it came on and I get sound whenever I turn it on. Does anyone have the Schematics for a M470VSE VISIO TV SCREEN?! Trying to fix it myself
Is this a good question?

@mtl4255 this could be an issue with your power board/LED driver or the backlight array. Remove the back of your set and post some pictures of all of your boards with your question. Let's see if we can identify some components on the boards that may have failed. Use this guide Adding images to an existing question for that.

Unfortunately there isn't much that can be done to repair a back light as the display is micro-soldered, and very difficult to repair.

@robialecm your answer is a bit off. The display is not micro-soldered and the backlight is separate from the display.
