Dell XPS 13 9333 No Display Backlight

Hello,

i recently replaced my dell xps 13 9333 top lcd assembly with a new one after breaking the old one.

However i observed that the new replacement screen did work but no LED backlight as shown in the pics below.

I made my research online and found out that my dell xps 13 9333 doesn't use an inverter board so i am trying to troubleshoot where the problem is comming from.

Please anyone with knowledge of the IC or Fuse controlling the backlight for the LED should please guide me accordingly.

Also,i circled the 40pin LCD connector to the motherboard...can anyone show me where to buy a replacement.

If you can see a faint image on the screen (no backlight), first try having the seller replace the screen you purchased under warranty.

If a second screen does the same thing, you'll need to look into a mainboard replacement.  The component-level repair you're looking for just isn't possible with the system you have.  If the backlight doesn't come on, the fault is internal to the screen or the mainboard.
