The macair is not an easy repair for any technician. The LCD and digitizer are very tight and require hardware and skill to be able to seperate and install a new LCD or backlight or cables. The best option is swaping out the assembly itself but that is costly. TDR refurbishes the LCD assembly having them ready for installs to happy customers. First removing the aluminium bezzel: \ Then removing the LCD afterwards removing the backlight components. Make sure to be careful with all cables! This is not a job for novice, only advanced techs with more than 5 years can perform this task without destroying the macbook.
