I'm no longer doing AIPS tech support (I was wearing too many hats and had
to take some off)... but I think I know the answer to this one.

It can't connect to your TV (XAS) or the TVSERV lock daemon.  One or both
are not running.  A TVINIT will also show this.  Best thing is to use
KLEENEX to exit from AIPS and then restart it.  

You can also check what's running via things like this from the unix
command line:

        ps auxww | grep XAS             (Linux, OSF1, *BSD,)
or      ps -ef   | grep XAS             (Solaris, Irix, HP-UX)

That'll show if XAS is running or not.  You can do the same for TVSERV
(possibly called TVSRV1 or TVSRV2).  XAS is what paints the "TV" on your
screen; TVSERV is an invisible daemon that decides what processes (local
and remote) can write to the TV.
