Current Draw Activated Switch

[Syd Levine \(AnaLog\)]

I need to turn on a couple of small security monitors when a TV is turned on.  In the past, they made a gizmo for the early personal computers that turned on the monitor, printer, etc. when the computer was turned on by sensing the current being drawn by the computer.  I have not seen them for years.   It would be trivial to open the TV and find some voltage in there only present when it is on and let it activate a relay, but when the TV dies, I would have to go through the procedure again.  A universal device with a plug-in for the TV would be nicer, and would not require cracking open the TV.  I think modern TVs draw a little line current all the time, so this thing would have to distinguish between a fraction of an amp, and the higher draw when the TV is actually on.   Any suggestions for a simple circuit?  Or is there a commercial product that will do the job?   Thanks in advance.   Syd H.
