My mike just stopped working, dead?

search for a wire or circuit problem like loose connection short or connection problem

You either have a loose ground wire to the dash or a bare wire touching metal on a dash bracket or firewall that is loose. It seems more likely its the latter like the wire swings away from the dash at speed and lays back against a bracket or the firewall when you stop or go in reverse. Having a fried wire is a good indicator that there is a short somewhere possibly caused by a bare or frayed wire.

The 2 wires should be + and - I think, is there any way of telling bewtween the 2?

Hi,it might be due to the wire that has cut inside the speaker area.

You will need to open the speaker area, and check if the wires are still in place.

And also, if the wires are intact, You will need to replace the speaker inside the headphone, That will solve the problem..

Thanks for using fixya....

I wonder how it sounds on another amp/speakers?
Did the person/shop who cleaned it test on another system and say it worked ok? A good dealer of the
AKG brand should be able to verify a problem.

Microphone capsules are very delicate and I'm afraid it sounds like you have broken yours and it will have to be replaced. Take the mike back to where you purchased it and see if you can get it serviced or if they can recommend someone locally who does that.

The service manual is at www.akg.com/mediendatenbank2/psfile/datei/19/C4194055d1fa264a7.pdf. You will have to replace the wiring that goes to the cartridge through the gooseneck.

Hi, my w300i speaker (mike) stopped working, my voice cannot be heard on the other side, but, when I connect the handsfree, things become fine.

Seems, the internal mike has got a problem, please suggest a remedy?

is it mandatory to get the mike changed, something similar had happened a year back and that time, they had said, that since the mike is a part of the board, the entire circuit board needs to get replaced.

Any idea, how much the board (circuit) will cost in Mumbai, India?

It sounds like you actually have 2 wires closely wrapped together. They are very fine and you have to make sure that you have separated all of the wires from each other. Generally you will have a red wire and a copper colored wire for the right side and blue (or green) and copper colored for the left side. you need to make sure that none of these little wires are still mixed with each other, otherwise you have a dead short and the speaker will not work. The insulation is very thin so there is no need to strip it, the insulation will burn off when the solder is applied

Check the mike plug to make sure that none of the wires have broke off.I would also check the mike cable with an ohm meter.
