There are numerous mistakes that can be made during this repair, here are the most common faults:
1) Damaging the diffuser
To unstick the LCD panel, a tool needs to be wedged in between, with little separation from the diffuser sheets. Coming into contact with the diffuser can easily scratch it, or alcohol can seep into the diffuser. Even finger oils can cause marks, so it is important not to touch the diffuser. Blemishes show up very easily when the display shows a light image.
2) Deforming the bezel
The bezel that lines the LCD can deform easily during removal, and while it can be bent back into shape, the deformation will show in the aluminum
3) Bad adhesive
Using too little, or bad quality adhesive can cause light to bleed out of the display, which can alter readings by the ALS (Ambient Light Sensor), can cause unwanted artifacts on the camera, or in some cases can cause the LCD to unstick over time.
4) Improper alignment
If the LCD is not precisely aligned to the frame, there will be uneven gaps between the outer edges of the LCD matrix and the inner edges of the bezel, which only become apparent after installing the bezel.
