I need help HP AIO dan97cmb6d0 with no backligth

[luzvel64]

Hello everyone, I have this HP AIO computer that does not have a backlight.

I was making some measurements on the 14-pin connector
PIN1=ISEN1 0V
PIN2=ISEN2 0.915V
PIN3=VLED 17.09
PIN4=VLED 17.09
PIN5=ISEN3 0
PIN6=ISEN4 0
PIN7=GND
PIN8=ID0 0
PIN9=ID1 3.2
PIN10=ID2 0
PIN11=ID3 3.2
PIN12=SIZE0 3.2
PIN13=SIZE1 3.1
PIN14=GND

If someone could guide me on what else I can measure or verify, I would appreciate it.

I couldn't find a schematic or boardview of this card, if someone had the boardview I would appreciate it if they could share it.

I thank you for your help.

Is there a backlit card on the screen itself?
