@ caspian i mean lcd problems we encounter white screen but laptop lvds cable is ok because change new screen shows display. what i mean is if there is a possible to fix a defected lcd screen that has white screen defective problem and the other is no backlight problem

Re: laptop lcd white screen and no backlight

I recommend continuing with the white screen.
connect the white screen and turn the laptop on. then measure voltage on all pins of the LVDS connector on the mainboard.
then we can reach some conclusion.
is the external monitor displayed properly?

most of the times its fuse on lcd which goes bad(White display). Led no light might be a fuse/resistance or the controller itself.

I have alreday clarified. If its Lcd, mostly its fuse blown Near Lcd connector on screen(Not on Mb). Applies only when the screen is milky white.
