    Tình trạng ban đầu:


    Nhận lại từ thợ, máy chỉ chạy từ Adapter, một số linh kiện như xung quanh IC sạc và fet sạc bị tháo bỏ.

    Tiến hành kiếm tra và sửa chữa:
    Thay thế các linh kiện thiếu máy đã nhận pin và báo charging nhưng lại không lên %. 1.jpg

    Kiểm tra điện trở gánh sạc pin PR156 có hai đường về chân 17 và 18 IC sạc pin thấy hai điện trở PR146 và PR150 tăng trị số từ 10 ohm lên hơn 500 ohm. Thay xong máy sạc pin bình thường.

    2.jpg

    Tra datasheet của IC sạc pin ISL88731c thấy hai đường CSOP và CSOP là hai đường kiểm tra dòng điện sạc vào pin bằng cách thức như sau:

    Giả sử dòng đổ sạc pin lúc pin 1% khoảng 2A, thì theo công thức U=IR với PR156 có giá trị 0,01 ohm sẽ là 0,01*2A. Vậy áp chênh lệch giữa hai đầu điện trở PR 156 là 0,02v cũng là chênh lệch giữa hai chân CSOP và CSON của IC 88731 được nhân lên x20 lần.

    Qua cơ chế như vậy khi nào chênh lệch giữa hai đầu điện trở PR156 = 0v báo về IO qua hai chân Data và CLK của IC Sạc làm IO hiểu là pin đã đầy, báo charging nhưng % không tăng.

    Còn khi quá dòng làm áp chênh lệch giữa hay đầu điện trở tăng cao khi X20 sẽ lớn hơn 3,3v và máy hiểu là quá dòng sạc ngắt sạc pin.


    Mong các bạn góp ý thêm. Thanks!

    Con sony svf14 mã main DA0GD5MB8E0 của em nó bị lỗi y chang như anh nói. Mở máy lên báo charging nhưng ko lên pin. Tháo ra tiến hành đo đạc thì thấy tại cuộn dây PL12 khi cắm pin và sạc vào thì có 12v tầm 6s thì điện áp tụt dần về 0v. trị số điện trở tại pr239, 241 ,242, 243. pr230 và 231 đều đúng. Đã tiến hành thay thử tụ lọc nguồn sạc, cặp mosfet sạc và cả IC 88731c nhưng không có kết quả. [​IMG]
    Tại jack pin thì chân số 1 - 2 có nguồn 12v và sụt áp về 0v sau tầm 6s. Chân 3 -4 có 3v3. Chân 5 6 đều không có nguồn. Đã thay thử IO NPCE985L luôn rồi. Anh em có thể giúp em phân tích pan này với

    Máy chạy riêng pin có được không bạn!
    Khả năng máy bạn lỗi mạch nhận dạng Pin!
    Bạn KT mạch đưa lệnh "-SYS_PRS" về mức thấp cho điện áp BAT+ vào main ổn định kn máy sẽ sạc OK!
