I have a LG UF695V which I like to use to play music from my iPad. When I set it to AV source, it will play the music perfectly while showing "no signal" on the TV.

Unfortunately after about 10mns, it will turn itself to standby, presumably as it doesn't recognize the audio coming in. Is there any way of preventing this?

I've turned the eco settings to off, so it should never set itself to standby.
