iPhone 6 with damaged backlight

I have an iPhone 6 with a backlight problem. The screen turns on with no light (I can barely see whats on the screen with bright light shined on it) but everything else still works on the phone. The touch screen works, apps work, it’s just the screen that’s really dim is what the problem is. Is this a filter that blew or is it the entire system?

I have found a nice recorded solution: https://www.youtube.com/watch?v=R8BedLX7JAg

but I would like to be sure that this is the correct issue. Anyone perform the repair which is shown on the video?

Haven't watched the video.

I would guess that, as you say, the backlight doesn't work.

Do you mean a fuse? Did you drop it before that happened? Maybe something got disconnected.
