Yes. 14″ and 16″ MacBook models (Models A2442, A2779, A2485, A2780) feature a serialised chipset soldered to the display (LCD panel) which is linked directly to the logic board, as an anti repair mechanism to deter third party repair and recycling of parts. Where this chip fails or is replaced, the serial number no longer matches, display artifacts will result:

• On the 14″ model, shadows will appear stretching down 2-3cm down from the top edge.
• On the 16″ model, the backlight will appear ‘blocky’/patchy and not light evenly when at roughly 50% brightness.

As part of our display repairs, we transplant the serialised chipset to mitigate these issues. This is a very complex repair and only a handful of stores globally offer this service – it is only possible through LCD replacement, if a shop is offering to replace the entire display assembly, then you will experience these display artefacts (unless they are purchasing the screen from Apple’s Self Service store).
