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.
More details:
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.
Bu iyi bir soru mu?

I FIXED IT FINALLY!!! The working Samsung LCD PN for my 2009 Unibody Macbook turned out to be LTN133AT09-G02. I literally ordered 5 LCD's for this thing (2 came in working, but cracked from bad shipping) until I found one that worked.

So, was it the vendor, or you who chose the wrong manufacture LCD?

I ordered my first few LCDs based on what the vendor said was compatible with the old LCD PN in my macbook. None of them worked. Later, I got my hands on a similar year/model macbook and used the slightly different PN from this LCD. Then, the manufacturer sent me a compatible part that actually worked. It looks like the LCDs they were sending me weren't actually compatible with the original B133EW04. I needed the LTN133AT09-G02 version.

Thank you for the clarification it may prove to be valuable to other DIYers just starting this project. Seems that "compatible" sometimes means fits" not ""fits and works like an Originally Manufactured Part.
