Hello there so I have a iPhone 5 that I repalced the screen and the new screen is very dim. Is it the backlight IC or the backlight filter? I stupidly reseat a the old screen with the battery plugged in it didn’t fry the logic board but it did fry the old screen and the backlight filter or ic.

Could be both but usually it is just the filter that blows as a fuse.

I also have another problem the rear and front camera stopped working the camera app just have a black screen 3rd party app also doesn’t works
