Hi guys,
my laptop (Asus N550JK, with touch screen - digitizer on the top of a matt lcd) Lcd broke down few weeks ago (purple/green tint etc) after some test i got convinced that the screen was faulty and decided to change it.
The screen is lg philips lp156wf4-sph1 (written on it) and it seems to be matt and IPS, so i ordered one online and installed it (I received a BOE screen), the display "works" but there is no backlight.. so i don't see anything, appart if i put a strong flash on it..
I find another seller, order another screen.. i receive the same screen.. same issue ! no backlight..
I dont know what is the problem, the when i pug in the former damaged screen (an LG philips) '''the backlight works smoothly''' (but the screen is broken heh.. as the former still has backlight, issue does not seem to come from motherboard, or lid switch)
What could be the cause of it .. ? Thanks in advance for your precious help
