I had an older (Dolby 5.1) Harman Kardon receiver in storage (HK AVR 70) that worked when I boxed it up. My son recently bought a house and we decided to get it out of storage. He has a Samsung PN42C450 plasma HDTV. Now that it's hooked up, it turns off after 5 minutes. Let me interrupt myself here - I'm fairly confident this isn't an overheating issue or a malfunction in the electronics of the unit.
The receiver is designed to receive a video signal from the TV to turn on automatically. I remember having the problem of it turning off after 5 minutes but I don't remember what I did (other than hooking up a cable from the video out from the TV to the video in on the receiver. Specifically, the manual for the receiver states:
"If a video feed is connected to the TV VIDEO IN jack L
during the installation, that signal is used to trigger system turn on. Even when the receiver is turned off, the presence of a signal at the TV VIDEO jack will automatically cause the receiver to turn on. As long as the signal is present, the receiver will remain on. When the TV or other source is turned off, the receiver will automatically return to a standby (“off”) mode within five minutes."
Problem is, the Samsung doesn't have a video out jack. Here's a picture of the connections on the TV:
Question is, without a video output on the TV how can I bypass the signal to prevent the TV from shutting off after 5 minutes? We don't need to TV to come on automatically but obviously we would like to have the receiver stay on for more than 5 minutes. I can't find anywhere in the receiver manual that talks about disabling this function (programming). Any help is appreciated.
