MacBook not powering at all/booting to black screen after HDD replace

crwdns2934249:0crwdne2934249:0:

Hi everyone,

My MacBook is not powering on at all or boots to a black screen after replacing the HDD. I’ve already tried every troubleshooting step there is: I’ve reset the SMC (though the button combo and removing the battery and holding power) , PRAM (the screen flashes gray then stays black), powered it on with the MagSafe (which boots it to a black screen), holding Command R for recovery (screen stays black) . I’ve tried booting to usb but the screen stays black (though it looks like the usb is being read because it gets warm after a while). Does anyone have any suggestions? Any help is really appreciated!
