[arifoxs]

Hello, I am from Indonesia, sorry if the words are less clear,

I have an Asus laptop a43sa, but no warranty, laptop screen broke yesterday, I bought a new one, and then I also bought a new LVDS cable, but after I plug it all, the laptop can not display anything,

I've tried with an external monitor, but it still can not display anything,

What is his fault?

what's wrong fan?
What graphics card is wrong?

please help me,,,,,
there is no solution in the forum in my country,
solution only sell components separately (Graphics Cards, Processors, RAM, etc.)

Hi, remove the new cable with the new screen, try to boot up with an external monitor, if nothing happens, you have a problem with the motherboard.

Start with, disconnect the cable for the screen, and verify with an external monitor. After if you don't have a picture on the monitor, check every connectors if they are properly seated.
