Custom power saving mode request!!

[Boushard]

Hi guys,

I recently installed my Pi on a LCD in my bedroom, my girlfriend watch some simpson's episode before sleep, so if nobody turn off the tv it will stay on, but dimmed, all night.

I search through the menus on the TV and found a shutdown timer when the tv had no input signal for 10min.

So I wonder if someone have ever try to make a script/fonction to "kill" the HDMI signal after a certain time and revive it when a IR or, in my case, yatse app send a trigger?!?

Thanks
