The Screen replacement is a change in both glass and LCD (which is what displays the image on the device).
This repair can be due to a smashed or cracked screen, colourful lines throughout the cracked
screen, blots that won’t go away or for a flickering light. The LCD will be
replaced. It’s important to get a cracked or smashed screen repaired straight away as even a
minor crack in your device can spider out over time, turning a small problem into a large and
more expensive one. Please note that during an iPad Air screen replacement, it will not
affect any other part of the device, this includes the motherboard. If you think the impact may
have damaged any other parts of the device, it would be advisable to get it diagnosed first to
avoid further damages and problems.
