I have no knowledge of this piece of equipment, but in a general sense I have a couple of ideas that might help if the problem is a mechanical contact. Take the bottom and/or top cover off. Then go through the motions that make the unit work in a dark room while watching the circuitry. If you are lucky the bad contact will be identified by a small spark as it makes contact. If this doesn't identify the problem you could try tapping various parts of the circuit with a non-conductive item like a pencil eraser. The bad connection should make/break contact when it is tapped by the non-conductive item.
Little Help With Mostly Dead Soldier
The Marantz SR 7000 quit last night, mid-movie. Complete shutdown for no apparent reason, then nothing. Try all the obvious stuff, nothing. Unhook everything from the back of it and, as I’m taking it off the rack, it turns on. (Yep, unplugged the wrong one. Damn rats nest.) So, I put it back on the rack and it turn off again….
Obviously, there’s just something loose in there – something I’m hoping I can find and fix myself. Pretty reliably, lay it flat and it turns off. Put it on its side, it’ll turn on. I’m hoping it’ll be something as obvious as a loose connection to the power supply, but I’ve never poked around inside it before – any guesses or ideas what I should be looking for?
Many thanks, and I promise to unplug it first this time. Honest.
