| As In Sony Ericsson Sets There Are Many Problem Of No ***** Speech Generally On Older Set These Problem Are Due To Mic But In Newer Sets There Is One Special Interface Ic For Mic That Is Would Damage
But I Found That Generally That Ic Dosen't Damage And We Dont Need To Change 70%
It Is How That In A Mic Point There Are Two Connections When We Put The Positive Probe To A Ground And Negative Probe To The Mic Position Than We Found The Value Shown In A Ohms Range Approx. 900 Ohms And Another One Approx. 1400 Ohms In That Case I Usually Clean Very Nicely Mic Ic Than I Dried It Up And Finally I Put The Switch Oil (generaally Avaliavle In The Radio Tv Spares Shop) Over The Mic Ic That Can Go Below The Ic And Keep It For About Ten To Fif**** Minute The Switch Oil Can Remove The Rust From Below The Ic Then I Heat It Up The Switch Oil Burnt It Up And The Rust Come It Out From The Ic And Little Bit Of Short Between The Legs Of The Ic Usuallu Removes.
Now Time To Clean And Dried It Up And Test It 70% Success On This Proccess. |
