PWM Dimming Control Signal low voltage drop LA-E841P

[nouriassafi]

JEDP pinout LA-E841P:
4,5 MLO (Main-Lane)
7,8 AUX (Auxiliary Channel)
9,10 VCCS (Power Supply +3.3V)
11 HPD (Hot Plug Detect)
15 LED_EN (BL_ENABLE Signal of LED Converter)
16 LED_PWM (PWM Dimming Control Signal)
19,20 LCD_VCCS (BL Power)

Have an issue with pin 16 (PWM Dimming Control Signal): low voltage drop!
Any help would be much appreciated!

LED_PWM(INVPWM) comes directly from SOC. Attach schematic if you have one for better understanding. There can be way out but you will loose brigtness adjustment control.
