Black Screen (poorly visible in a dark room)

I have been using this macbook since a year ago. I frequently closed and opened the lid to save the time required for the system start-up. Everything was going well, since one day the display partly turned black in the half left side, then it moved to the right half side, and eventually all the display turned black. I took it to a dark room, and the display was poorly visible. I could connect it to an external monitor, and it is working normally (now using it to write this message). I run Apple Hardware Test, and got this message “There may be an issue with the display. Reference code: VFD004, Additional reference code: VFD001”.

I verbally consulted a local repairshop and the response was fully replacement of the display lid by a fee which I found it high.

Any help would be much appreciable!

What I cannot guarantee is if you order a replacement display cable, which may solve the problem if it works. It is not from iFixit so I cannot guarantee if this will work or not, so do it at your own risk!

What I can guarantee is that if you buy a replacement display from iFixit that it will work and if it does not you will get a replacement with no questions asked. I will provide a link to the iFixit guide for replacing the screen in that guide is a link to the screen replacement from iFixit.

@ajcooke01 Thanks for the nice response.

First, I would like to try to replace the display cable, hope it works.

I searched youtube for the replacement instructions, but no good results.

Do you have any good video to show the full replacement procedure and the tools required?

Thank you again.

You will need a Spudger and a P5 Pentalobe Screwdriver. The only thing is that there is no video or guide for this though and you will be on your own doing it. My guess is just scour the underside after you open it up and look for a similar cable. If you find a similar cable then yay you! Try and replace the cable with the replacement cable and if it does not work I think you are best just taking it in for repair. As @oldturkey03 and @ntsparadise said you might have to get a fuse replaced for the backlight too and that is super hard to do-it-yourself.

backlights, either CCFL or LED. Your LCD is fine it sounds like, I believe these had LED backlights and a backlight fuse, its most likely the connector but it could be the fuse. https://www.youtube.com/watch?v=u1ZGhd2A...

@ntsparadise Just to be safe I always assume the user asking the question is not very skilled at fixing teeny-tiny parts on computers and will likely have trouble doing so. The video you posted even I would not be able to complete and is not very helpful in my opinion. If it really is that fuse that's blown then the user that asked the question would definitely have to take it in to be serviced.

@ntsparadise Also, if the backlight fuse was blown then the backlight would not function at all. The user that asked the question said that the backlight was half-working for a time.

@ajcooke01 but if it is your backlight LED driver, PWM or the fuse, a display replacement will not fix this. This "display partly turned black in the half left side, then it moved to the right half side, and eventually all the display turned black." sounds pretty much like a backlight issue to me. I'd at least check it...

@ntsparadise @ajcooke01 @oldturkey03

Thank you all for helping me.

Since I don't know the solution, so I am waiting for a concluding decisive response from you all.

@ajcooke01 - What would be important as the first diagnostic steps would be to look at the lids logo is it lit? And given the odd left and right screen illumination I'm suspecting the LVDS connection on the logic board is corroded so the power feed to the display is shorting out. This is where an inspection of the connection would be the next step (popping off the bottom cover). Otherwise it's the LED driver logic and its fuse.
