Raspberry Pi not booting

[CheeryPi]

Hello,

I am new to the raspberry pi. Anyway, I installed raspbian Jessie on my raspberry pi 3, I configured a static IP, tight VNC and a NAS. I was about to start on my torrent, when i thought it was best to reboot using "sudo reboot".

All was fine, it posted.. then went black on my tv.
However I can still access my Pi from the VNC and NAS.

Any help would be appreciated.

Thanks.

Make sure that you start VNC on a different display ( not :0 ) above or equal to :1

Make sure that your VNC server is running on a different virtual terminal than 1 (Use 7)

Did you change anything in /boot/config.txt ?

Thanks for replying.

How do I do that?

I can't remember if I did change anything..

Thanks
