Member: 14004 Status: Offline Thanks Meter: 6 | T230 MIC problem Sony Ericsson T230 was dropped on the floor, and somebody was trying to repair it after that. Microphone doesn’t work, one of the little BGA chips near bottom connector is missing. As you can see on attached picture, one of the contacts for this BGA is broken. I was trying to get full schematics of T230 but without any luck. Please help me: which contacts of this BGA I must connect with shortcut wire? (I know that this IC is only some kind of electrostatic protection). I don’t have this IC, so I cannot check it’s connections with multimeter. If you have one, please check which pads are connected to which ones. If you have full or partial schematics, please send it to me (or give me link to download them). This phone is important to me, please help me. BR, johny3310 |

Member: 110512 Status: Offline Thanks Meter: 0 | When you look as on the picture and counting from left to right. Pins 3 and 4 in the first row and pins 3 and 4 in the last (4) row. Connect 3 with 3 and 4 with 4 you will have mic connection. Good luck |
