Dont work LCD display Asus zephyrus s15 gx502

[b.rakhshani70]

Hello Friends
I have an asus zephurus s15 gx502 laptop, unfortunately I don't have a display on the laptop LCD, but it works fine on the hdmi
This happened when the battery socket was damaged during removal.
Now the voltages I have are as follows
+3VS_LCD_OC is activated at the moment of turning on the system and quickly turns off
And on the pins
LCD_BLEN_CON
LCD_PWM_CON
I have no voltage even at the moment of starting.
In addition, the LCD cable is also healthy

PU8501-volatge on all pins after power button press?
Resistance to GND on pin 6 of PU8501(No power attached).
U4503,pin1-Resistance to GND?

There is no pu8501 in my pcb
I have attached a photo of it for you
However, the voltage of its pins is as follows:
1= 0V
2= 0V
3= 20V
4= 0V
5= 0V
6= 0V
Resistance of pin 6 to ground = open circuit
Resistance of pin 1 in u4503 to ground = 10MΩ and increasing
