No backlight - Screen replacement didn't solve the issue.

Hi there!

Thanks beforehand to anyone who’s willing to help.

Mi Xiaomi Mi A2 Lite decided one morning to not turn on the backlight (not dropped, no water damaged). Autobrightness is off and max brightness is selected from the slider. I can see the image showing if I point external light into the screen.

It seemed to me that the backlight in the screen module went bad, so I decided to replace the whole screen.

No luck. After replacement, the issue is the same.

Can anyone help me solve this? I can’t see any obvious damage, not in the connector, not any smd blown, burnt… I attached pictures of the main board, both sides.

Thanks.
