How do I get these filters back on and align them to the new LCD?
I am in the process of replacing the LCD of my iPad 11”. The process went mostly fine with the exception of the front facing sensors. During the LCD removal process, the filters came loose from the two ambient light sensors. Two are white and one is green. The green one and one of the white ones came from the sensor without filter, while the other came from the sensor with one of the filters still attached. The one already attached doesn’t appear to be green and throws me for a loop. Perhaps, the two sensors are non-symetrical?
Three questions: How do I put them back in place and in what order? Second, how do I realign the flex cable on the new LCD? Unlike other LCDs I’ve replaced, there’s nothing to register it against other than the two barely transparent see through holes. Finally, how are the sensors adhered to the LCD? I’ve heard others using superglue, but it’s not very forgiving, especially for an already difficult to align sensor.
