Mini displayPort to HDMI allows selection of  TV (Insignia LCD) display for  a few seconds, but then begins cycling through the search routine. At one point, I got a few seconds of sound, but never a picture. I can detect the display when the TV's input is set to "TV", but when I input HDMI, the search routine starts.

Please help...

    "Search routine"?  I assume this is somthing your tv does.  I don't understant that phrase with respect to a mac.  Must be a problem with the TV then.  But make sure of the mini-diplayport connection to see if it is firmly seated.  They can sometimes look pushed in but they are not.  Also may be a defective cable.

    Let's see if I understand this...

     

    You open the Displays preferences.  You see an Arrangement tab with both screens (main and TV).  You click Gather Windows.  At that point the Arrangement tab shows only the main monitor or disappears entirely and only the resolution preferences window for the main monitor is visible (TV's resolution window is not showing, even offset behind the main monitors resolution preferences).

     

    Is that correct?

    I see the arrangement tab only on the main screen. (nothing ever on the tv)

     

    That is all you ever see if it detects the TV.  If there is an arrangment tab click it.  Do you see two little "screens" in the Arrangement window, one of which has a little white bar at the top (indicating your main screen's menu bar)?
