Samsung Galaxy Pro 360 blank LCD display

[suiramix]

Samsung Galaxy Pro 360 laptop like new condition, power up with no splash screen/logo, black screen, boot-up on Window 10 and works fine on external display. Remove the back cover and there is no signs of damaged /burn components. At eDP LCD connector (30 pin), the R010 fuse is OK but no voltage (pin 21-22). No schematic avail for this model. SM3201B chip has Vin=18V at pins 4,5,6 but not output at pins 1,2.
Any help will be appreciated...

Re: Samsung Galaxy Pro 360 blank LCD display

Hi again,
The Galaxy Pro 360, is a15 inch model: NP950QDB-KB2CA. "Samsung update" app recommended BIOS/MICON upgrade to ver. P09AKG file (6/24/2022). Using the external monitor, the BIOS upgrade went ok but same situation: blank screen, no backlight, no image. The SM3210B (Silicon Mitus ?) could be a AMOLED Display Power Supply...Can anyone can share the original BIOS dump for this model.
