Why is my display so Dim?

So basically here is what happened. I started noticing that the screen on my steam deck would start to flicker between super dim to bright very sporadically. I would originally fix this by turning the display brightness all the way up. This would stop it from flickering, but any time I turn the brightness back down it would continue to flicker. I have done all the resets and restarts so I don't believe its software related.

After awhile I started to notice that it was getting worse and the screen would stop flickering and just completely stay dim. Now I do see the screen and I can still manage the steam deck it’s just that the brightness is all the way down and I have no way of increasing it.

Edit:

I have some pictures of the steam decks circuitry and I have not noticed anything obviously unplugged or damaged. Another update to the problem the back light just never comes on now.
