DC cable to trigger Monster Power HTS 3600

People sometimes get abberant results if they use stereo mini-to-mini plugs... You want mono ones if possible. If that isn't it, you may have a bad relay or something.

If you have a voltmeter, you might also check to make sure the Proceed is really going to +12V and staying there...

I had a similar problem with my new HTS 3600 after less than month of use. The "clean power on" light was flashing, no components were getting any power, none of the other lights were permanently on, but it kept on going through a cycle in which there was a clicking noise, followed by the the row of lights on the bottom coming on for less than a second.

I called Monster, they said it sounded like a bad relay, and they asked me to send it back so they could ship me another unit.
