Display switches off when opened more than 45 degrees

Hi

I have a late 2016 13.3" MBP with function keys. Lately, I've been facing an issue where the screen will go black(dim) when its titled more than 45 degrees. It's out of warranty as well

I am still able to make out the contents on the display using a flashlight. Went to the Apple Store, they want to replace the entire display assembly and are asking for $650 dollars for the same

Is there any fix for this?

回答此问题 我也有这个问题

这是一个好问题吗?

We don't have any guides yet on the new 2016/17 MacBook Pro's. But the teardown can give us a clue on whats happening 带功能键版本的 MacBook Pro 13寸 2016年末款拆解. If we jump down to Step19 we can see how this series inter-connects the display and the logic board. One of these ribbon cables is likely damaged in some way.

Carefully pop off your bottom cover and do an inspection of the connectors do you see any staining from liquid damage? Do you see any distorted parts or missing screws? Take some images so we can see if you see anything.

Most of us tech's haven't seen them yet as most issues are still covered under warranty. Do be careful as this still maybe covered under an extended warranty issue (defective part type of issue) so you don't want to mark your system that you've been in it.

This sounds Like a defective Lvds cable.

The lvds cable carries the backlight signal and video signal within the cable

if there is a loose connection in the cable wiring it will cause the symptoms you are having

As a hobby i fix apple computers and i had a problem with a lvds cable that had severed video wires internally. The computer only presented a white screen when turned on no apple logo because it was only showing the backlight and no video signal

How do I check for the LVDS cable connection?

完成的

open the back and disconnect the cable where it goes into the logic board then hook up the mac to your tv if it works ok the i would be 99 percent sure that it

when moving the screen like you say the broken cable shorts back together when less than 45 degree displaying a normal screen i would find a good used one on ebay and try it if ur computer is not under warrenty

im very confident this is the problem

Jack - This is a very different configuration!

First the cables (2) carry iDP signaling not LVDS. All of the Retina systems use iDP signaling.

The cable interconnection is what I pointed to in my answer above.

完成的

ok well i'm saying the cables would most likely be the fault then from my experience they both do in theory the same thing supply backlight and video

完成的
