Okay, here’s the rundown.
A1502, bought in March 2014, has unexpectedly produced a fairly problem that is nasty.
Went along to start one and *chime!* but no screen day. Apple logo design in the relative straight back lit up, backlight ended up being obviously working, but ZERO display workings.
Okay, and so I plug within an monitor that is external. Absolutely Absolutely Absolutely Nothing. «HDMI signal perhaps not detected.» Okay, therefore the Googles is done by me, browse the reddit, etc etc. Reset NVRAM/PRAM, reset SMC, no fortune. Decide to try booting Command+D Diag. mode, and production on outside monitor! But, white progress boot club hangs at 1/2way for 3.6 hours. Thus I Safe Boot (Power+Shift). Finally, I am able to make use of my outside monitor! I could enter into my mirror and mac displays, to ensure that I am able to offload my information. Great.
I am aware the int. display screen is not urgent link working– that is not the conversation.
Here is issue: once I boot ordinarily in clamshell-closed mode, outside monitor works completely. Nevertheless the 2nd the lid is opened by me(i.e. usage keyboard) EVERYTHING GOES BLACK AND TURNS OFF. Then, i need to boot into safe mode to again use the mac! As well as the period repeats it self. What is the culprit here? Iris movie card, Logic board, free connector that is internal or every one of the above? Could be the interior display problem and also this problem related at all?
P.S. Congrats for getting this far. I’m sure the writing is thick.
I’ve precisely the issue that is same the exact same model (A1502). Any kind of «soft» solutions for this dilemma? Think about your macbook Nick? Did you correct it?

Had the actual problem that is same you after my MBP had dropped from the bed.
Had a screen that is completely black not really a backlight. Tried tapping regarding the casing nearby the display cable and pressing the black colored club in at the back of the laptop computer nonetheless it did absolutely nothing. Tried resetting NVRAM/PRAM – absolutely nothing.
I realised that i really could sign in and unexpectedly the keyboard and Apple logo lit up while the backlight had been working therefore I figured there was clearly something very wrong aided by the display. Linked it to a display that is external got absolutely absolutely nothing then again I attempted booting it whilst pushing cmd + D plus it labored on the outside display, nonetheless it totally turn off the moment I attempted to sign in.
Sooner or later realised I happened to be planning to need certainly to start the instance to see in the event that display cable had been damaged. I have never ever done this prior to so had been a little stressed but a screwdriver was ordered by me set from Amazon and waited a short time. Followed the guide posted above to start the situation and found the display cable. Tried wiggling it only a little and screwed the situation right back together and frustratingly it did absolutely nothing. Very nearly quit at that point and ended up being resigned into the undeniable fact that I would need to take it to obtain repaired.
Nevertheless, we offered it one last go except this right time i disconnected the battery pack as well as the display cable and plugged them back. Place it all relative right right back together, turned it on and BOOM! Screen turns in, everything back into normal! Therefore relieved that i have fixed it!
Thanks for most of the advice in this thread, you are all lifesavers!
Many thanks with this solution. We actually have the exact same issue on my MBP. I cant start to see the thread that is entire. Do you have got a link for in which the guide you utilized to troubleshoot the display connection can be bought? Many Many Thanks.
I can not remember precisely what type it had been but i do believe it had been this 1:
Simply skip actions 7-10 since it’s not required to get rid of the fan/antenna cables/iSight digital digital digital camera. Unplug the display plug and cable it back and determine if that really works.
Many thanks!I dropped mine today also it had been fine that is working, but a couple of hours later the display screen went black colored ( straight straight back light nevertheless on). Tried establishing pram, smc and got a a display in the outside monitor, but had been hanging on boot the same as OP. started using it booted in safe mode, but nonetheless absolutely nothing from the main display. Only for kicks we offered the part for the laptop computer a smack that is goodwhile driven down) and shockingly it booted find from then on, like absolutely absolutely nothing ever occurred. In order to be safe we started it, disconnected the display and battery cables and reseated both. Took about ten full minutes (consist of 8 minutes to obtain the right screwdriver). Thanks once more to Nick for composing within the issue very well also to Jay and Rob for answers that struggled to obtain me. I happened to be moments far from driving into the Apple shop!
Thanks great deal Rob.
