Actually, you're unable to view any image I think...

Presumably this works.  Before going any further, you should try a
"tvinit" to see if you can communicate with the running XAS image display
server.

You probably don't have the TV lock server (TVSERV) running.  This task is
started along with XAS, the message and tek servers at AIPS startup time
and usually appears in a "ps" listing as TVSERV.EXE (or TVSRVn for unix
sockets, i.e. "aips tv=local" mode).  On Linux, "ps auxww | grep TVS"
should show it:

 USER       PID %CPU %MEM   VSZ  RSS TTY      STAT START   TIME COMMAND
 pmurphy   4826  0.0  0.4  1412  612 pts/0    T    15:37   0:00 ./TVSERV.EXE

If it's not running, then simply exit AIPS with the "kleenex" command
(this cleanly shuts down all running display servers) and start it up
again.  Look carefully for errors on startup, especially if TVSERV has
problems. 

TVSERV doesn't pop up a window; its purpose is to take care of lock
requests from any and all AIPS processes that may request access to the
XAS "tv" image display.
