Backlights not working after reassembly.

Texto:

I don’t know a lot about MacBook circuitry and I don’t advertise their repairs but there is one customer who does send them. They don’t arrive in a shell just the boards. After repairing the ones that can be repaired they are tested and sent back. I then wait for the text telling me that some of the backlights don’t work. This happens even when the boards have no liquid damage.

When they are returned it is either the fuse or driver damaged.

Can anyone shed some light on how this issue is occurring? It is always on MacBook airs 2012 to 2015 models.  Could it be connecting them up under power or a faulty magsafe or daughter board? I don’t see how a backlight circuit can get damaged in transit.
