Broken mic

[Fredde87]

Hi,
Has anyone got a quick fix solution for a broken mic? Mine seems to have broken. Others cant hear me at all, if I shout as loud as I can with my hands forming a cone around the mic you can just about make out some noise on the other end. Running htc WM6, hard reset doesnt solve it.

Could it be the usb port is fucked and it believe an external microphone is connect? The usb port seems "tighter" than usual when I try to insert a usb cable into it.

Unfortunately the USB port has nothing to do with it. The mic is a standalone piece soldered onto the board. Did you spill any water on the phone? It could have even happened from being in your pocket or just condensation forming. Either way, you probably have to replace the MIC which I'm not sure how to do because the way it is soldered onto the board its almost impossible to do yourself, so you will most likely have to send it to HTC.

Well I agree the Mic is well nigh impossible to replace yourself. Although I probably agree the Mic is the problem, I would not 100% rule out the USB port as, if connections are shorted in there, it could replicate the connections made "as if" a handsfree were connected. The USB connection would be a cheaper fix and is more straightforward - however given that companies will charge just to look at it, you might as suggested end up cheaper getting HTC to do it. Prepare though for a tough decision if its a hardware problem because it could mean a m/board replacement. (Touch and go whether you'd be cheaper to replace with a second hand device?)

Any easy way to test if it is the usb port? Its a vodafone branded hermes flashed with htc wm6 (just did it a couple of weeks ago which is a shame now).

Other than visual inspection I cannot think of an easy way and testing would need some comparison data. But maybe someone with a handsfree kit might be able to think of other changes that would be apparent if the handsfree were connected???

Curiously, I dealt with a case yesterday where someones mobile got water / condensation in the mic. The result is that when in a call the other person:

Can only hear a faint noise if you shout very loadly in the mic
But can easily hear a rushing noise if you blow into the Mic.

Is it possible yours got wet?

(by the way despite efforts with a hairdryer it still does not work - may have caused the coil to stick internally once dried?)

I see what you're saying about a USB short, but that would mean that the person on the other end shouldnt even be able to hear a faint noise when yelling into the MIC because if the USB is in-fact shorted to make it represent that a hands-free is connected, shouldn't the MIC be shut off completely? Either way this situation is the worst you can be in, I repair cell phones and I have never been able to repair a mic due to the way they are mounted, I've had countless RAZRs with broken MICs that I couldnt fix even though you can buy the part. Best of luck though!
