A1466 MacBook Air 13 inches No Backlight Repairs
In this repair, we have an 820-00165 with backlight issues. We started from the basics, by checking the status of the FUSE, then we moved to the backlight output, where we measured 8.6V suggesting the circuitry is not boosting. We then headed to the region of the backlight chip, from there we found two resistors that were damaged by corrosion, including a missing pad for one of the resistors for the backlight enable signal.
