HI, I have a lenovo y430. I dropped my lcd laptop and the lcd was cracked. When I connected it to external display, it worked just fine. SO, I have ordered a new LCD screen of exact same version. Now when I replaced my screen, the backlight will not come up. Is there anything I need to set up to make the backlight glow? or do you think my inverter has aproblem? The backlight wasworking fine before I replaced the new one. But now, the backlight does not work for any of the two screens. Is there a chance it shorted out or is there any setup to make the backlight work? The laptop in itself is working fine.
Your advise is greatly appreciated.
Thanks in advance
Srikanth.

Did you make sure you plugged the back light power wire into their connecters at both the light and motherboard correctly?

Did you also make sure the switch is in place to turn the back light on and off when the lid is opened and closed?
