AIPS works, tekserver works, but the TV doesn't come up

    This is seen most often on Linux systems. Almost certainly your X
Windows configuration is set to use a 16-bit display. The AIPS TV can
only support 8 and 24 bit displays (32 and 24 should be equivalent).
Type "xdpyinfo | more" and if you see this:

      
        default visual id:  0x20
        visual:
          visual id:    0x20
          class:    TrueColor
          depth:    16 planes
      

    ... then this is the problem. If it says 8 or 24, then the TV
should work. If it says 16, then you should alter your X configuration
to allow either 8 or 24 bit display. You should use the supplied
tools, e.g. XConfigurator under Red Hat Linux, to do this; only edit
the XF86Config file directly if you know exactly what you're doing!
