There are two problems in your phone, First one is your keypad and the second one is Microphone.So for keypad you need to change the keypad IC (filter) and fir mic you have to change the Mic/Mic IC.Therefore my comment is to contact mobile repairing shop.Good luck

Hi i am using the audio technica at2035 condensor mic and the m audio mobile pre 2nd gen. audio interface. yesterday the mic was working fine with no problems but today for some reason i have to really...


This mic has a 10db pad or attenuator switch near the bottom of the barrel... make sure you haven't accidentally engaged it.

If that's not.... it try changing the lead. Also the power supply on your preamp could be failing.
These are a few cheap things to try before spending money for fixing.

29 nw LTD no audio on receive out the speaker in the radio or through the ext speaker and on transmit no audio.Radio shows a 4 watt dead key


If you take your external speaker and plug it into your PA jack in the back and key up your mic do you hear anything. If so then its not your IC chip if not its your IC chip and it will need to be replaced.

No sound coming back


Is the radio set up correctly? Is the volume turned up / squelch turned down?

If they can hear you but tou cant hear them, try opening the radio up and checking the speaker connections.

Ill need to know the result of those questions and tests before i can help further...

Internal MIC not working


If you are using xp, try going to the control panel, sound and audio devices, click on audio tab.
to check the mic settings, click on the volume tab under the sound recording sections. Make sure that the mic is selected and the volume turned up. It may be working only to record, not to hearback without recording...so you may have to actually be recording or talking to someone to know if its workings.
To check the sound, check to see if your audio device is selected under "sound playback" section...and make sure that all channels are unmuted and turned up. you may also have to check the volume control on the laptop (actual buttons on the pc) if there are any, and make sure that the volume is up and unmuted there also.
Hope this helps.

yeppers you have a common problem of the audio output IC being bad or a defective speaker. If there is an external speaker jack, try another speaker just to make sure. Good Luck
