Is the LCD screen only broken or are there any other damages?

Hi!

My screen started malfunctioning suddenly; the backlight seems to be weak, colors are not normal and the screen retains some ghost images. In the photos it may not be visible but the screen has also an orange tone instead of white.

I checked the settings on the accessibility menu and are okey.

Hard reset and restore don’t seem to solve it.

I replaced the screen a year ago, but I checked the connectors inside and seem to be okey.

Is the screen just defective, or is the motherboard damaged?

Thanks for the help!
