    Hello. My Aiwa AV-D57 no longer powers on. It doesn't smoke or show any signs of a short.. but nothing happens. I found that this wire is unplugged, and I don't know what it is.
    *PIC*
    Can anyone tell me where it goes? I've looked high and low through the receiver's circuit boards and can't find a connector that it plugs into. It's coming off the power transformer board so I think that may be why it's not turning on.

    Well apparently I can't post an image because I'm too new to the board, so you can find it here:

    Hmmm, any answers... Well it would be tough with a scematic of some sort, if you can't find an obvious place that wire would have been attached...

    It would probably be just a feed through hole on a circuit board. Maybe even one that appears to have no solder in it.

    Hard to say.

    Well, I still don't know where it goes but I think I know what it does. I finally got my multimeter (I bought it off eBay for $7.. gotta love eBay) and two of the four pins test at 17 VDC. I'm pretty sure it's used to power the front LCD and operate the buttons. I think the other two pins are part of a "Power good" signal. We'll see.

    I was just reading you post - did you ever fix this? I have the same problem with a used AV D57 that I just bought off of ebay.

    I have concocted a small web page with pictures of the insides of my AV-D57. I too have had trouble with power-up; it generally takes three tries to get it to come on.

    in case I can't post links:

    Hope you can get it fixed!

    ps. anybody wanna buy a recently retired AV-D57? has everything but the box.
