MacBook Air A3240 screen replacement in Dubai: in at lunchtime, ready the same evening
A customer called us about a 13-inch M4 MacBook Air with a damaged display. Coloured lines ran down the left side of the screen. The MacBook reached us at 1:50 in the afternoon, and by 6:23 that evening it had a new OEM screen. It was ready to collect that night.

The enquiry
This one started with a phone call. Straight after it, at 12:53, we put everything in writing on WhatsApp so the customer had it in one place: the price for an original screen with all service charges included, a one-year warranty, two to four hours of work, and free pickup and drop-off if they wanted it.
An hour later the MacBook was on our counter. We logged it, opened a job sheet and sent the customer a copy by email.
Before and after
Why lines on a MacBook screen rarely go away
Coloured vertical lines usually mean the display panel itself is damaged. A restart or a software update won't fix that, and the lines often spread over time. It is also why an external monitor is a useful test: if the picture looks fine there, the Mac is working and the problem is the screen.
The good news is that a screen replacement doesn't involve your storage. Your files stay where they are.

On the bench
Sribin handled this one. We quoted two to four hours and it took about four and a half, so we told the customer partway through instead of leaving them to wonder.
A late pickup, sorted
The person collecting it couldn't reach us before 7 pm, when we close. So we sorted the bill over WhatsApp and left the MacBook at our building reception to be picked up after hours.
Before that, the customer asked one more thing: could we send pictures of the MacBook with the lock screen open? It's a sensible request after paying for a new screen. We sent a photo and a video a few minutes later. The reply: "Thank you so muchhh."
What we checked before it went back
Every device that leaves our bench goes through the same quality check. For a MacBook that covers:
- Display: brightness, colour, and no lines or dead spots across the whole panel
- Keyboard, trackpad and Touch ID
- Charging
- Speakers, microphone and camera
After that the device is cleaned properly and packed for the trip home.
Price and warranty
An OEM screen replacement for the MacBook Air A3240 usually costs between AED 1,400 and AED 1,700 at Techman. The exact price depends on the part available on the day, and we confirm it on WhatsApp before we start. Pickup and drop-off are free.
The repair comes with a 12-month warranty.
If your MacBook screen has lines
Back it up if you can. Connect an external monitor if the screen is hard to read, and run a backup before the Mac goes anywhere.
Don't wait for it to spread. Lines that start on one side often take over more of the screen.
Ask what screen they are fitting. A good shop will tell you straight away, and put the warranty in writing.
