<br></div></div></blockquote><div><br></div></div><div>I would use an IRSEND to power the tv back on when the system resumes from suspend (eg <a href="http://askubuntu.com/questions/141702/how-to-run-a-script-after-the-system-resumes-from-hibernate-suspent-to-disk" target="_blank">http://askubuntu.com/questions/141702/how-to-run-a-script-after-the-system-resumes-from-hibernate-suspent-to-disk</a>)</div>
<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>

<br></blockquote><div><br>Thanks <span name="Joseph Fry" class="">Joseph, I will try the first approach, I installed the "ddccontrol" package, but how could find the TV information?<br><br>Now I am not at home and the TV is off, this is what I get:<br>
