Hello,
i have a samsung np550p7c laptop. The laptop screens shows white/black image only, but with external monitor works fine. Both the screen and the cable works 100% well(tested). The problem is that before i bought the new cable the old cable had snapped cabels and i used to connect/disconnect the cable from the motherboard repeatedly on a turned on machine(stupid as hell) and the screen work. Now it doesnt work neither with new cable,old cable or screen(all tested on other laptop works fine) so i quess i must have short circuited something on the mobo. I doubt that someone can help me on this but ill give it a shot. Maybe someone knows what did i do to the mobo? Maybe i fried some condensator or the male pins that the cable connects to? The laptop is old enough so i wont be getting it fixed for money, but i have soldered some things earlier so maybe i could make this work.
This is the image that it transmits. At start its fully white, after loading a bit it turns into this:
