Help with Asus N56VB screen

Hello everyone,

I made a complete mess. So, I wanted to update the wireless adapter for my N56VB and replaced the Intel centrino wireless-n 2230 with an intel wireless advanced-n 6235. I reassembled the computer but forgot to plug the screen. So, once again I disassembled it plugged the screen and it worked fine, but after some time it strted having some problems. I tried once again to disassemble, re plug and reassemble and now the lcd screen does not display anything at all, even though the backlight turns on (it's all black). I checked with an external monitor and the video output is working, fortunately. The Asus repair center here in Mexico is taking too long to reply to my request, so I may have to repair it by myself. Does anybody know what could the actual problem be? Somebody told me it might be the cable that goes from the screen to the motherboard. Please! I need help!

 

Probably a connection issue; try reseating the cable once more at both ends (at the screen and at the board). If the screen is lighting up, though, it's getting power, which means it might be another issue unrelated to the cable.
