Here ya go..iffin you can solder...attach a small wire to the jumper just above the big plug..You should leave it unplugged..attach the wire to a ground..I'd think even under one of the screws would be fine.The jumper is about the size of a paper staple close to the plug.Heres the pictures.Its J110 or close..between the orange wire and the plug...It attaches to pin 5.

Here's the reason there's volts with it unplugged and keeping it muted..if you follow the mute line on to the main board,you see a resistor tied to it and being feed from a 4.9 volt power line..this keeps it muted till you short the line to ground.with no volts going up on these lines,the mute circuit goes inactive.


What a challenge to see this on my 5" phone screen.

Wow. You did all this on your phone, I bet that was a challenge :-)
OK, tomorrow I will solder a wire to that jumper and then to ground. I'll report back here when I finish with it.
I will leave the big green plug disconnected. Should I leave the smaller 5 pin disconnected as well ?

I'm not sure how you can look at a wirering diagram and trace all those wires and then know what they do as well. You must be some kind of electrical engineer . :-) All I know is now I have a new best hero....hahahaha :-)

You can leave the 5 wire plug off as well.
As far as what I do..I learned how to read those fold up road maps to navigate our road trips when I was very very young...Reading schematics is the same...Just a road map to different places..each place has it's own character...
Lemme know if it works..I'm sure others may have this problem and would like to know about it..

OK, I soldered a wire onto that little staple thingy below the orange wire and grounded it. WOOOOHOOOO, I once again have sound.
I never would have found this if I was looking by myself. Thank you so much for all the help and not giving up.
If ever we should meet I owe ya !!!!! Brewskies, or a steak or both or whatever :-)
Thanks so much again.
