MacBook Air 13" Screen Replacement, Lines On Screen - MacBook Air 13" 2017

Posted by eFix Ltd on

In this case study, we have a MacBook Air 13" 2017 A1466 model with lines on the screen. The MacBook otherwise functions fine via an external monitor, so the screen/LCD will need replacing to resolve the issue. In this repair, we replace the LCD panel itself, instead of the whole top assembly, which works out cheaper for the customer and ensures we can reuse their original camera and bezel (which often aren't original on full assembly replacements). Visually inspecting the device, there are no cracks in the screen to cause this issue, but the screen is not showing up at all, being mostly white with different...

Flexgate Repair, Screen Cuts Out When Opened Fully - MacBook Pro 13" Retina 2017 A1708

Posted by eFix Ltd on

In this case study, we have a MacBook Pro 13" Retina 2017 A1708 model where the screen shows a spotlight effect, then completely turns off, when opened fully. This is a common issue known as 'Flexgate' which affects 2016-2017 MacBook Pro 13" and 15" models. Apple cover the 2016 13" models under their free repair program, but they do not cover the 2017 13" models, or any 15" models. Visually inspecting the device, there is no internal damage to cause this issue, but we can see a fracture in the backlight cable as pictured below; This issue affects a huge number of...

Some Keys Not Working, Keyboard Replacement - MacBook Pro 13" Retina Early 2020 A2251

Posted by eFix Ltd on

In this case study, we have a MacBook Pro 13" Retina Early 2020 A2251 model where some keys are not registering when pressed. Disassembling the device, there were no visible signs of liquid entry internally, and the logic board luckily did not suffer damage. Some parts did have visible liquid staining (the fans and bottom cover, which was minor), but no electrical components. The next step was to try a test keyboard, to ensure the issue is definitely related to the keyboard. Plugging in a UK keyboard for this model, we were able to verify that the keys were now working correctly when...

Battery Symbol, Not Charging - MacBook Pro 13" Retina 2017 A1708, 820-00840

Posted by eFix Ltd on

In this case study, we have a MacBook Pro 13" Retina 2017 A1708 model (board number 820-00840) which is only showing a battery symbol on the screen when trying to turn it on, indicating it has no charge. When connecting a known good charger into either of the USB C ports, it is not taking any charge. When we see this issue on the USB C MacBooks, this usually points to a problem related to the charging ports or the charging circuit, since the device has some signs of life. Disassembling the device, we could see no signs of liquid damage or...

Dead, Randomly Stopped Turning On - MacBook Air 13" 2015 A1466, 820-00165

Posted by eFix Ltd on

In this case study, we have a MacBook Air 13" 2015 A1466 model, board number 820-00165, which stopped turning on randomly one day, but was still showing a charger light. The customer reported a 'Service Battery' warning, which had been present roughly a year before the device completely stopped turning on. Disassembling the device, there were no immediate signs of physical or liquid damage, the device looked clean and like it was well looked after. We started measuring through voltages to find out what exactly is preventing the MacBook from booting, since it was likely missing a required voltage, or...
