So to dig over an old thread, but may be of use to someone else who is seeking enlightenment.
I've had this problem a couple of times with 7.2.x... I run my raspberry pi via a battery to act as a walkman when I'm a man about town. So occasionally there is an unexpected power out!
This can cause corruption of of the sdcard with the moode OS on.
The definitive symptom is the /boot/config.txt is an empty file. Why this file is affected I don't know, but there we go, if this file is empty (or wrong) its not going to work.
The automated disk-fixer may create an FSCK00xxxx file when it tries to recover a file system flagged as dirty, or so very dirty dirty... I inspected the contents of the latest FSCK file and it looked to be a complete config.txt. With some trepidation, I copied the FSCK file to config.txt, rebooted and it worked.
My /boot/config file is as below. Take care, I don't think a corrupt file here could damage your hardware, but use caution if you don't know what any effect of changes you make may have.
disable_overscan=1
hdmi_drive=2
hdmi_blanking=1
