Hi, I'm starting thread to let everyone know about the issue i'm facing with my Macbook Air 2013 model. It is strange that my Macbook air actually turn on but there is no display, looks like plain black screen even after turning on my laptop. I took to apple authorized service center and they just simply told that Macbook Air MLC needs to changes and it roughly costs around 600$( and they were not sure if this fixes the issue). I stay in a place where there is no apple genius bar which may actually perform diagnostics and tell be the best possible solution. It been 4 months since i used my Air, yesterday i decided to open the back panel of Mac and tried to figure out what was the issue and saw that fan is spinning when i hit the power button but there was no display. Can anyone let me know what exactly the problem with my MAC. Do i really want to change the MLC with 600$ (Warranty of 60 days) or can this be repaired. If it is repairable please let me know where this can be done... Thanks in advance..
