View Full Version : T28 low volume on Mic
When I use my T28 mic the other people hear me very bad, the mic as a really low volume, I'm trying to fix this phone after is fall in the water. <br />The battery as been replaced and all is ok aparently (already update version) but the mic as a realy low volume. <br />Could it be only the mic that needs to be replaced or do I have to replace some other components??
I don't have many experience in repairs and I need to know if the phone as any chance.
Hi!<br />Mic 100%. You can test the cover from another phone...
I tested the phone with one "hands free kit" and thi Mic is also very low. So the problem is really not the Mic from the Phone. <br />Can someone give me some help how to fix the problem in the phone board (what components should I change) please...thanks
Anyway, try with cover from another phone. If result will be the same, try to rehot lower chip...
Of course check the lines on PCB. If there is no any other solution try to clean PCB with alcohol and dry it with hot air.<br />Good luck
