Screen backlight doesn't work.
hi.
I just replaced the screen on my Macbook air, I bought a whole new LCD assembly, i've put it on, made sure all the wires are plugged in properly and whatever. I then turned it on, at first i didn't think it worked but then I realized it did, just had no backlight so I tried turning the backlight up, and it says the backlight is getting brighter and dimmer but nothing actually happens.
Is this a problem with the actual screen, or might it have something to do with my cable-plugging-in skills?
Is this a good question?

ok i have double checked the LVDS cable, and yes its fully plugged in no problems there.
Some history, i was given this laptop by a friend a couple months ago, who for some weird reason punched the screen and the keyboard a few times, figured it was unfixable and gave it to me, when i got it the screen backlight worked just he cracked to LCD screen so nothing displayed, but the backlight still got brighter and dimmer when the buttons were pressed, which kind of eliminates any problems with the logic board.
So i bought a 2nd hand complete LCD display assembly including hinges and cables, ready to just screw on, which i did but now the backlight doesn't work, no problems with hinges or anything else, the LVDS cable did look... well lets just say it was brand new when i put it on, but everything looked fine with it, no cut wires etc.
so i guess the LVDS cable may be dodgy?

thanks for the advice, i wasn't planning on taking the LCD assembly apart in a hurry! i had to do that to my old one thinking i was only going to replace the screen itself, but as it happened i needed a new hinge as well and when this full assembly came up i figure it would save me a whole lot of hassle!
I'll contact the seller i see what he says.
Thanks for your answer.
