No backlight after replace sd connector

I’m trying to repair a faulty sd connector, once I’d finished to change the connector the backlight didn’t power on.
LCD connector was replaced also after bented some pins.
The switch power on and I can ear touch and open games, but I don’t have image and no backlight.
I messure the lcd IC voltage and I see the +5v and -5V. On Backlight connector I have the enable pin with OL, no voltage and the next right pin only has 4V (not 17V to power on backlight)
Diode messures from backlight circuit on the back of the board is OK.
LCD connector was checked several times and diodes messures are OK
I’m waiting to a new LCD replacement to check it
Does somebody where to look to reach the enable signal to power on backlight.
