MacBook Air won't start - chimes but screen black

Hi All,


I have a MacBook air purchased in Sep 2013 that I've never had the slightest problem with. After shutting down normally last night, I tried to start it today, and this is what happens:

1. I press start

2. After a few seconds I hear the chime

3. Nothing else happens -- screen remains black and the keyboard is dark


I followed all the steps outlined here: My MacBook pro it does not start, including trying to reset the SMC and the PRAM, but this did not help.


Yes, I checked the brightness of the screen. Yes, it has a good connection to power, the power cord light shows amber.


I am running Yosemite 10.10.1


I really don't want to go to the Genius Bar!


Thanks,

Jwol

MacBook Air (13-inch Mid 2013), OS X Yosemite (10.10.1)

Hello, this response is a few years late, but I recently had this issue with my 2013 MacBook Pro and I was unsure where to post the answer to this question.


Symptoms:

My computer would start up, fans would run, Apple logo would light up and chime would sound, but no display. I could see the backlight of the screen was on (different color black on LED screen), but nothing would actually display on the screen.


Things I tried:

I tried all the hard resets and even went into the Apple Store to see if they could find a fix. The only thing they said they could do for me was replace the display (costing half the original price of the laptop or more).


What worked:

I opted to not purchase the display and I wanted to transfer all of my data from my laptop before making a decision.

I decided to hook up my laptop to an external display (another separate monitor) to see if I could at least view my files.


THIS FIXED MY SCREEN. As soon as the HDMI cable was plugged in and I restarted my computer (held down power button until display was clearly off, pressed power button again to start "normally") my display suddenly worked again.

NOTE: I had this issue again several months later, and my screen was once again saved by simply plugging in an HDMI cable.


I don't know how or why, but plugging in an HDMI cable saved me from buying a whole new laptop.
