MacBook backlight not working - display or backlight ic?
I have a problem with my backlight of my macbook air, when it suddenly stopped working. I sent to apple for diagnostic, which initially they assume it should be whether the logic board or the display, and after 4 days they said that it's the display and the cost to replace it would be around £450.
I did not sent for repair, but instead I sent it to iSmash (a repair shop in the UK) for diagnostic, and after running the diagnotic for a week, they said it is not the LCD that is broken, but the 'backlight ic' on the motherboard?
So I am wondering why is it quoted differently between these two premises and is 'backlight ic' an integrated part of the 'display'?
