The VNC Service is simply stopped/down. You simply need to restart the 
service.

For the record check_tcp is a pretty weak test of last resort. I know 
from experience there have been times when check_tcp returns OK, the 
port is open, but vnc is wedged in a way that you cannot actually use it 
to retrieve the screen. You may want to check out the check_vnc plugin I 
wrote, it is freely available here:

http://www.nagiosexchange.org/cgi-bin/page.cgi?g=Detailed%2F1558.html;d=1

or just search at NagiosExchange.org, it is the only vnc plugin there.
