dell alienware m17 r5 LA-L761P liquid damage no image on lcd 2red 7blue runs on external

[larrysito111]

got here a liquid damaged alienware

the laptop had damage in the area of the kb9542qf2 all sorted and now laptop working and turns on but i have no display

so if i start and connect usb-c display it works otherwise it is giving me the 2red and 7blue

so with the usb-c external monitor is getting to bios and OS

otherwise not

so if it is in the os and i connect another lcd via onboard hdmi it is working no problem 2 lcds (1 usb-c + 1 hdmi)

but still not the internal monitor

(tested 3V and 5V going to the lcd LVDS)

can someone advice me as it is i think an o-led display how to check if it is just the lcd now to replace

thank you all
