Raspberrypi2 does not connect samsung es8000

I have an working raspberry p2 but it does’nt work on my samsung tv ES8000.
What do I have to do to get it working?
I have used the raspberry on an other samsung tv and it worked on it.


How does it not work?

Nothing shown on screen?

Remove power from RPi2, check HDMI cable is firmly seated into both pi and tv, connect power again.
