Hi there regrding on my previous post about my laptop that has no light on display i manage to troubleshoot on led and motherboard lcd flex cable connection that lcd maybe ok it has output voltage even in motherboard. I did a troubleshoot using a 30 pin lcd from old laptops so still no lights but ihas image. I wonder if it is cable flex?when i test it again the lcd that i test shows imitating light when you press a power the screen flickers for light but dim only.. here is thing if possible does my laptop has proximity sensor for sleep/wake when u open up the lid and close it.. i tried to search were possible the proximity sensor. But it says its on the lcd automatically. Hope some can find schematic diagram that can share for thats a big help for me. Thank you all.
