Ajutor cu TMP47P860F

Recommended Posts

Salut,Am o statie CB care are incorporat in ea radio si casetofon.Statia respectiva are un TMP47P860F care cred ca e defect.Pe display nu afiseaza nimic si uneori cand ating cu degetul unul dintre rezonatoare(cel conectat intre pinii 44-45) afiseaza ceva dar numai segmente sau unele functii care ar trebui sa le faca aparatul.Oare cum as putea sa-mi dau seama daca e defect, sau nu, microcontrolerul sau defectul e din alta parte?Eu nu stiu absolut nimic despre microcontrolere asa ca orice sugestie e binevenita. Va multumesc anticipat.

Din pacate n-am idee cum ai putea sa te prinzi daca merge sau nu daca nu stii ce trebuie sa faca, sau daca nu are un fel de built-in test. Ai putea sa incerci sa te uiti cu un osciloscop pe pinii de la display, sa vezi daca arata la fel de fiecare data sau e aleator semnalul.
