Replaced LCD. Boots to Apple logo, then display goes blank
I am a technician, and I replace hundred of LCDs a year, mostly on PCs, but I have worked on Macs before.
I put in a new LCD in my macbook, turned it on, and got the mac chime and the apple logo and spinning wheel. After a few seconds, when it should go into the login screen, the display turns off (backlight and everything). I've tried booting into safe mode and booting off of the disk. It does the same thing both times. If I pull the hard drive it will stay on the white screen with question mark file forever. and if I boot into single user mode (terminal) it stays on. I thought it might have been a defective screen, so I sent it back and got another one. It does the same thing.
I bought the plastic unibody macbook off of eBay. It has a bleeding LCD due to a fall. I pulled the old LCD out and ordered a new one based on the part number of the old LCD and the model and year. The PN I pulled out is a B133EW04 and the new LCD is a LTN133AT09. It doesn't look like anyone has ever removed the bezel before. I'm pretty sure it had the original LCD in it.
Is this a good question?
