MacBook Pro A2159 lcd flex cable replacement guide

I am unable to find a guide on how to replace just this cable on the macbook pro 2019 A2159. I see plenty of people reppacing the whole screen or the backlight cable. But I am completely unable to find one about replacing just the flex cable.

Block Image

The macbook displays colours weirdly. And i have figured out its because a piece of dirt has punctured the flex ribbon cable. So i would like to just replace the cable instead of having to replace the entire lcd.

This is the cable I want to replace.

My question, I guess, is if someone has a guide on how to replace just that cable.

There is a point we just can’t get to as our skills and available tools prevent us, sadly this is one of those spaces.

Think of it this way your loved one has a brain cancer who would you allow to do the surgery? Your family doctor or someone who specializes in brain surgery? Clearly the specialist will have a better outcome in the surgery!

This is the same case here. You will have a hard time just opening the display assembly just to gain access to the bonded ribbon cables to the glass LCD panel and you don’t have the tools to properly remove the cables without lifting the Metal Oxide pads the cable needs to bond with, if that was the issue.

In this case the chroma effect you see is not the ribbon cables it’s a defect in the T-CON logic which is that small logic board hanging from the display that the LCD, backlight & camera ribbon cables attach to.

Sadly you need a new display assembly.

Here’s one source TheBookYard UK you need a used display assembly a new display bought from China won’t have the firmware loaded so the camera won’t work. Lastly here’s the guide to put in on MacBook Pro 13" Two Thunderbolt Ports 2019 Display Assembly Replacement

Thanks for the answer. I know what you mean. But i would much rather try and fail replacing the cable than just not trying. And it for sure is the cable, as the effect stops when i dont have the screen open more than 20 degrees. And also the fact that there is a literal hole in the cable haha.

I also have no attachment to this laptop as i bought it broken to practice fixing issues like this.

@cjb2811 - Flex issue is where the tension is applied to the T-CON board or the solder joints within it. Read up on how a LCD TV works, to get a better idea on why the issue is not the cable or the LCD as the LCD driver logic is within the T-CON board, the cable merely drives the X and Y lines of the LCD.
