Hi everyone, After I replaced the keyboard of my Macbook pro 2012 unibody, the macbook is stuck in the white screen without logo. I tried to rest NVRAM, but it is still white screen after I released the buttons and hear the second chime. Then I thought it might be a hard drive cable problem, I replaced it with a new one. But still the same problem, stuck in white screen, no logo, and NVRAM does not work. I am nor sure if there is any thing else I can do. Really appreciate any advice or help. Thank you very much!
Disconnect the display ribbon cable and plug in an external one is the external screen still white?
