mạch đồng hồ bị hiện tượng lạ

[anhhuycan83]

các bác chuẩn bệnh e cái mạch đồng hồ này sao nó bị hiện tượng lạ quá. khi cắm điện vào thì các Led bảy đoạn nó sáng loạn xạ.
cụ thể 2 led chớp chớp theo mỗi giây thì nó sáng hoài. các led khác hiển thị sai hết. có đoạn thì sáng mạch, có đoạn thì sáng yếu, có đoạn thì ko sáng. chả hiểu luôn

[chung1608]

mạch này nếu là chip cấy thì "bótayDOTcôm" chụp lại mặt sau đi bạn

[anhhuycan83]

đúng là chíp cấy đó bác. hình nó đây:

[chung1608]

đúng là chíp cấy đó bác. hình nó đây:

dùng VOM thang đo x1 kiểm tra độ sáng của led 7 đoạn có sáng đều hay ko. Sau đó thay thạch anh khác thử xem (thạch anh 32768 Hz)

[pvc28]

Bạn thay thử thạch anh xem sao, lấy xăng đánh sạch mạch, trước tôi cũng gặp trường hợp như bạn ....

[fireman]

Mấy bệnh này thường là do các chân xung ra của con VXL có vấn đề, hoặc các trans kích dòng cho các số, điện trở từ chân VXL tới các nét bị hỏng chứ thạch anh thì hiếm lắm.

made in china hả bạn
vậy sao thay ic

Mạch đòng hồ bị chớp khi làm thức tế cảm thấy như bị rung giật

khi cấp nguồn thì ở số giây đếm lại từ đầu 00 phút vẫn đúng ,Mạch đòng hồ bị chớp khi làm thức tế cảm thấy như bị rung giật, cấp điện 4 đến 4 lần thì mạch mới bắt đầu hoạt đọng bình thường , cấp lần đầu nhảy lạn xạ hết
các bác xem mạch giúp với
