Chosen Solution
I’ve had a lot of troubles with this MacBook Pro (2010 15") and it got to the point where a whole new logic board seemed to be the only solution. GPU faults etc etc. Recently it started not starting up properly - it would boot and chime then the screen would just go black and the laptop would start getting insanely hot and the fans went into over drive, like all CPU cores were maxed out. It seemed like it was time for a completely different logic board. I sourced one on eBay that was clean pulled from a working machine, and fitted it to my MacBook, but alas the same problem seems to be happening (minus the insane fans and overheating). https://www.dropbox.com/s/1yk3gxuklocgmv… Any ideas what’s going on here? Could the LCD screen cable be causing this? Plugging into an external display shows a blurred image of the login page, which does not dissapear when the screen turns itself off. I’m aware of the capactior issue with these models - this had been done on the old logic board, but not the new one. The problem persisting however would suggest that is not the issue. Before changing the logic board I did an Apple Hardware Test, which showed no faults. Mac OS - High Sierra Have also done the following with no luck: NV / PRAM resetSMC resetPowered up without the batteryBooted into safe modeBooted into recovery mode Thanks for taking the time to read this and any suggestions would be welcome! Cheers SOLVED: Replacing the screen cable fixed all these issues!
OK let’s breakdown your issues At the start we see this:
Then we get the Apple icon and the bar to about the halfway point
Then Green Screen!
Then we get to the about the end of the boot
A which point it finishes to a Black screen. Image 1 shows your displays backlight is bad! This could be the light bar in the display and/or the LVDS cable MacBook Pro 15" Unibody Mid 2010 LCD Replacement Image 3 Causes of Mac Green Screen A malfunctioning hardware componentLack of available free space on MacCan’t locate the booting filesMac trying to access unavailable dataScreen driver missingMalware attack on the system Try booting up with an external boot drive, did that work? The replacement logic board may need repairs!
