<div><br></div><div> To determine if the TV is already on, there are several approaches you might take:</div><div>1. do an edid query (should only work if the tv is on)</div><div>2. use a serial cable, if your tv has a db9, and see if you get a response from the set.</div>
<div>3. ping the tv (assuming it has network connectivity)</div><div><br></div><div>I have also read that you could wire the tv's usb +5v and GND to a serial port's CTS and GND and sense the CTS status of the port using a python or C program... but that's far more complicated.</div>
