I´m using the raspberry pi 2 together with osmc since a while and it works pretty fine with my setup:
Device: Raspberry Pi 2 B
Installation media: microSD
Power Supply Type: universal USB micro power supply (white)
Power specs: 5V 2000mA
Peripherals: TV Sony Bravia
Storage Device (incl. Network Sharing Protocol):
OSMC version: 2016.07-1
XBMC version: Kodi (16.1). Platform: Linux ARM (Thumb) 32-bit
Audio/Video Output: HDMI
Config.txt Extras: hdmi_force_hotplug=1 but tried all other options
Problem: No HDMI signal - or better, no image on the TV. I only have a black screen.
I do can log in via SSH.
I changed the HDMI port on the TV.
I checked the HDMI port of the TV with another device.
I checked the cable by using it between PC and monitor.
I connected the raspberry to my monitor.
I changed the power supply to one with 1.8A.
I formated the sd card to noobs and after that to osmc install image.
Back to my osmc backup I checked tvservice again:
osmc@Raspi:~$ tvservice -n
osmc@Raspi:~$ tvservice -s

OSMC is recognizing the TV but the screen stays black.
