    Harman Kardon AVR 110 powers off randomly

    I was given this stereo receiver and was told it had a problem that it would just shut off an any time. As I looked at the inside I could see that one of the caps was bulging. I have replaced that cap and all the ones on the main amp board. but still does the random shutting off. The amp from what I can tell is not overheating. When the amp powers off you can hear the relay click as if someone hit the power button on the remote or the front control.

    One possiblility is that there are bad solder joints on the board.

    HK receivers, from what I read, tend to run a bit hotter than others.

        And this is sold as a premium product? I would feel ripped off.
        Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
        For service manual, schematic, boardview (board view), datasheet, cad - use our search.
