Hi,

you can check if the backend is runnig by issuing the following in a 
terminal:
ps auxw | grep mythbackend
it should output something like this:
root at mythtv:~# ps auxw | grep mythbackend
mythtv    1065  7.9  2.7 422412 57036 ?        Ssl  21:23   3:35 
/usr/bin/mythbackend --logfile /var/log/mythtv/mythbackend.log --user mythtv
root      2571  0.0  0.0   4012   756 pts/0    S+   22:09   0:00 grep 
--color=auto mythbackend

If you only get the line saying grep ... its not running, you could then 
try to start it manually by running
sudo service mythbackend restart
or you could start it by hand in verbose mode by running:
mythbackend -v
and post the output here.
You could also run mythtv-setup in a shell and check the output.
