This business started in 2009 doing MacBook screen replacements. We bought new, Grade A LCD panels from LG and Samsung brokers, replaced only the broken LCD cell, and reused the rest of the display assembly. That kept part costs low and meant we could offer screen repairs at a fraction of Apple's price. The customer got a new panel, not a used one. We took pride in that.
That supply chain no longer exists. Apple has closed off LCD panel sales to independent repair shops. The standalone LCD panels still available for modern MacBooks are factory rejects with visible defects; dead pixels, discoloration, backlight bleed that we would not put into a customer's machine. We tried. The quality is not acceptable.
For current-generation MacBooks, the only quality option is a used display assembly pulled from another machine. These assemblies include parts you don't need (back cover, hinges, webcam, antenna cables), which raises the cost. The display will be used, not new.
The result: for screen replacement on modern MacBooks, our pricing is similar to Apple's. Apple charges $399-$799 depending on model. We charge $300-$700. In many cases, Apple is the better option for a screen repair, and we will tell you that rather than take your money.
Where we still add clear value is logic board repair, liquid damage recovery, and data recovery. These are repairs where component-level skill makes the difference between a $300 fix and a $1,200 board replacement, or between recovering your data and being told by Apple that it cannot be done.
