Need Help on TDI Volume

[ahmedjust]

Hi All,

My TDI volume was loud and working fine , few days back the volume came very low , you can't even hear something with the speaker , then test with the headset I can hear very low sound and the detector work fine with put metal near the coil
I don't have away to send to whites for repair ,
Need some one to show the audio components on the pcb so I can check and replace them.


Thanks

Most components are SMD, so it is very difficult to repair it. If you have the accoutrements to repair a smd pcb, then it is easy to locate the fault component. Anyway.... check where the speaker is connected so to see who is the audio stage.
Good luck
