This Macbook Air flickering screen repair was no ordinary case either. The customer was experiencing flickering screens occasionally.
Macbooks are a type of device which gets most of the bizarre problems out there, especially when the issue comes and goes as it please. Very rarely do we have a straightforward Macbook repair unless it is a screen replacement.
After testing it for a day, we have noticed that after some work, it stops flickering and returns to normal. We were pretty sure initially that it likely is a faulty screen. Especially considering the little scuff marks on the edge of the screen and extensive travel history of this Macbook :)
Identifying cause of Macbook Air flickering screen – Attempt 1
We tested a new screen on the Macbook to eliminate the screen problem, but after a couple of hours of testing, it starts flickering again. This shows again how resilient screens on older Macbooks are compared to the number of screens we are replacing on the new retina models, which turns breaks even with a tiny knock.
Identifying cause of Macbook Air flickering screen – Attempt 2
Knowing that screen is not the reason we are having flickering screen issues on this Macbook, we start looking at electronic issues. There were no visible liquid signs at our first inspection. Hence we ruled out electronic failure. We were wrong!
We start crawling the logic board under a microscope inch by inch. Finally, after probably an hour of staring at the components, we located a darker spot that didn’t look right.
Usually, with liquid damaged Macbooks, we have clearer signs of a trace which liquid followed. That is our indication of where to look on the chips, as there are probably more than 50,000 components on this logic board. Having a black component on a black solder mask covered board also is not making our job easy.
Identified components that seem to have some organic material corrosion. It seems like either rice or other oily food particles sneak inside the Macbook and get stuck on top of this component. Causing long term decomposition and oxidation of the MOSFET responsible for carrying backlight circuitry of the screen.
Macbook Air flickering screen repair process
After we identified the area of damage and potentially problematic component, we could now fire up our rework stations soldering irons and dig into the schematics.
The great thing about this model is that it has been on the market for almost 7 years, with minor modifications on how it’s engineered. This allows us to have wider access to chips, schematics and replacement parts, together with knowledge and know-how of how every chip of the system works.
Due to the extensive corrosion, traces have completely decomposed under the MOSFET. As a result, we had to resort to some unusual soldering skills. Including soldering the chip under an angle and creating traces between the chip and the board on the air. True 3D soldering masterpiece.

Therefore, it should be used as general guidance of what to expect of such repairs.
In case you have a similar device and need the repair, always rely on professionals. These are sensitive electronic devices, and small mistakes may cause you a fortune.

Repair before Replacement
We are committed to reducing e-waste in Australia. And the way how we do it is by educating our customers and providing affordable Macbook Repairs.
Although our best intentions and hard work, this is not an easy task. Customers must accept that cost of high-quality electronic repairs, is a third to half of the price of a new device. While we do the repair we target common planned obsolescence design mistakes to ensure the longevity of the laptop usability.
That said, if we buy a new one or write it off via insurance, it does not guarantee that the new one will not meet the same fate as the older one pretty soon.
Quite often, we see accidents reoccurring within less than 6 months gaps. If we can save 1000$ or even 600$ today by repairing our faulty Macbook is great. That’s an extra half laptop cost ready to be spent on another one when the time comes.
When that time comes is up to us to buy a new one or keep pushing the one we have, but delaying it by a year or three is always a good starting point and saves another Macbook polluting our planet.
