Re: Audio jack identification


When I plug headphones, the main speakers don't mute anymore and
in the headphones I can hear what sounds very much like the difference
between the two channels in mono (probably the jack now connects one
channel to both outs and the other to the ground). When the phones are
unplugged, the sound coming out of the main speakers is okay.

The little blades inside must be broken.

No matter what, you are going to have to disassembly the machine to
reach the bottom of the motherboard...or cut a hole through the case
just under the jack. If you do the later...expect another layer of PCB
and/or a metal shield (or maybe nothing). You may well find that the
jack is NOT physically broken...that the solder joints have come loose
("cold solder joint") and that a touch with a soldering iron will fix
the problem. Be aware that the motherboard may to a multi-layer device
(anywhere from 2 to 7 layers)...so surgical soldering technique is
mandatory. Good luck...you are going to need it.
