the HDMI on my pi seems to be acting up, I've gotten it to boot 2/3 times after a few minutes, in the middle of configuring a controller in emulation station for example.
It's booting, my TV is recognising the HDMI input is coming from a Pi but I'm getting no signal.
I've tried different HDMI, Charging cables, Keyboards/mice. I've expanded the file system already during my initial boot (8GB class 10 SD card).
Beyond a reinstall of the OS i'm out of ideas.
