No Backlight after replace driver
Hi all!! and Happy New Year!
After a water damage in my Macbook air A1466, I lose my backlight
I cleaned all the PCB board with alcohol, I checked the LCD connector´s pins and the fuse (they are ok) and I replaced the driver U9701. I reset the PRAM too. Everything seems ok and I have 22 Volts at the backlight input (PPVOUT_SW_LCDBKLT pins n.3 and 4 ) but the screen doesn´t have light. Please anyone could you give any idea how check what is happening?
Thank in advanced for your help.
PD: The signal in a external monitor is perfect.
Is this a good question?
